Education System in India Free Essays

Education in India is seen as one of the ways to upward social mobility. Good education is seen as a stepping stone to a high flying career. Education System in India currently represents a great paradox. We will write a custom essay sample on Education System in India or any similar topic only for you Order Now On the one hand we have IIMs amp; IITs that rank among the best institutes in the world and on the other hand there are number of schools in the country that don’t even have the basic infrastructure. Even after more than 50 years after independence we are far away from the goal of universal literacy. But on a positive note, Indian professionals are considered among the best in the world are in great demand.This signifies the inherent strength of Indian education system. The Educational structure in India which operates at all conceivable levels from pre-school to post doctoral is of monumental proportions. According to a World Bank report there are more than 7,40,000 formal schools; more than 3. 6 million teachers are working on full time basis; there are more than 175 Universities offering under graduate and post graduate courses and about 6000 colleges affiliated to these universities. The educational structure in India is generally referred to as the Ten + Two + Three (10+2+3) pattern. The first ten years provide undifferentiated general education for all students. The +2 stage, also known as the higher secondary or senior secondary, provides for differentiation into academic and vocational streams and marks the end of school education. In +3 stage, which involves college education, the student goes for higher studies in his chosen field of subject. This is a comprehensive website on education in India. It gives detailed information on education and career options in India. Vision and Mission of educational system in IndiaThe vision of any institution should be to inculcate knowledge and power to the younger generation. Vision/ Mission has a great impact on learning. The mission of educational system in India should be the all-round development of children. The Indian education system comprises pre-school, primary school, secondary school , higher secondary school, and higher education (graduation and post-graduation). Although primary school is compulsory, this has been difficult to achieve in practice and India is still struggling to raise its literacy rates.Through school, students are taught a uniform set of subjects including languages, math, sciences, and social sciences. Higher education in India provides an opportunity to specialize in a field and includes technical schools (such as the Indian Institutes of Technology), colleges, and universities. Higher education in India has evolved in distinct and divergent streams with each stream monitored by an apex body, indirectly controlled by the Ministry of Human Resource Development and funded by the state governments.The important universities are called Central Universities and these are ma intained by the Union Government. The private sector also has a strong presence in Indian higher education. The Indian Institutes of Technology (IIT), National Law School, Bangalore; All India Institute of Medical Sciences; Indian School of Business , Hyderabad; and the Indian Institutes of Management (IIMs) are renowned for their superior standards of education and compete with the best in the world. Primary and Secondary Education Several factors work against universal education in India.Although Indian law prohibits the employment of children in factories, the law allows them to work in cottage industries, family households, restaurants, or in agriculture. Primary and middle school education is compulsory. However, only slightly more than 50 percent of children between the ages of six and fourteen actually attend school, although a far higher percentage is enrolled. School attendance patterns for children vary from region to region and according to gender. But it is noteworthy that national literacy rates increased from 43. 7 percent in 1981 to 52. percent in 1991 (male 63. 9 percent, female 39. 4 percent), passing the 50 percent mark for the first time.There are wide regional and gender variations in the literacy rates, however; for example, the southern state of Kerala, with a 1991 literacy rate of about 89. 8 percent, ranked first in India in terms of both male and female literacy. Bihar, a northern state, ranked lowest with a literacy rate of only 39 percent (53 percent for males and 23 percent for females). School enrollment rates also vary greatly according to age (see table 9, Appendix). How to cite Education System in India, Papers

Challenges Faced by the Business from Cyber Security-Free-Samples

Question: Discuss about the Challenges in Cyber Security for Business. Answer: Introduction The following report is based on the determination of the challenges faced by the business organizations from cyber security. The use of internet by the different business organizations has changed the way business is done in the modern world. The use of this ultra modern technology has no doubt changed the approach of the business organizations towards its customers. Cyber Security consists of different technologies, processes and controls that are designed to protect the systems and network data from any kinds of cyber attacks. Nowadays most of the organizations implement technological tools to carry on different business operations (Cherdantseva et al., 2016). The advent of the computer technologies and internet has both been a blessing as well as a doom for the operations of the organization. Therefore the main challenge of the management of the business organizations is to protect their systems from being harmed from any types of potential online threats. The report gives a clea r idea on the kind of threats being faced by the organizations and the measures that the business organizations implement to counter such threats. Project Objective The topic of the report clearly indicates the objective which is to determine the different types of security measures implemented by the organizations to counter the threats posed by the different cyber attacks. The report has been a great source of knowledge on how the organizations implement cyber security techniques and what the ways by which these threats are handled. The report has also the objective of providing insight into the world of cyber security and the harassment that the business organizations face as a result of such harassment. The successful completion of the following assignment will help to provide a transparent picture on the learning outcomes of the business. This includes the definition of cyber security, the ways by which cyber security is arranged in the business organizations and last but not the least the ways in which it is implemented within the organization. Project Scope The topic that has been selected for discussion is itself one of the trendiest topics. This is because cyber security is now a household name for the business organizations. Almost all the business houses that implements computing technologies and uses internet to operate in the modern market faces issues with cyber security. The project thus takes a large number of different information into consideration. The consideration of such varied information helps to make the scope of the project much larger. The report can act as a great help for the future researches on the same topic. Such researches can receive important information regarding cyber security from the current research. Literature Review Cyber Security Cyber Security means the different body of technologies, progress and different practices that are constructed to protect the different networks, programs and devices from different cyber attacks in the source of virus, spam and other kinds of online attacks (Fielder et al., 2016). The cyber security may also be termed as the security to information technology. Importance of Cyber Security in Business Cyber Security is one of the most important elements of a business organization as it is needed to store, collect process and analyze the large number of information on the computers and other computing devices. This information is always sensitive in nature and any forms of data leakage can harm the business operations as well as the reputation of the business. The management of the organizations transmits the secret data through a number of different networks and to other devices in the process of doing the different types of business. Therefore leakage of this kind of sensible data will seriously affect the management of the business organization (Graham, Olson Howard, 2016). The growth in the volume and sophistication of the cyber attacks is a great worry for the different business organizations as they become more vulnerable to different new attacks with the passage of time. Therefore it is utmost necessary for the business organizations to have a perfect defense in place to sa ve themselves from any kind of threats that have its source from the computer technologies like internet. Challenges of Cyber Security for the Business A study conducted by, Graham, Olson and Howard, (2016) cybercriminals are going to create 3.5 million new, unfilled cyber security jobs by the year 2020. If this is compared with the year opening of 2016 it will be seen that there has been an increase of 350% in just a span of 4 years. The alarming rate of such an increase will be a great source of problem for the business as because it directly implies the rate of increase in the crimes originating from the internet. The business organizations are the most vulnerable in the line as they are going on investing large sums of money to hire different IT professionals so that they can save their business from the hands of such crimes. The ultimate aims of the business are to secure and safeguard the interests of their customers and provide them the best products and services accordingly. A calculation in the year 2017 alone accounted for a huge sum of $86.4 billion on cyber security measures that were spend by the different business orga nizations alone. There are a number of different types of cyber security challenges and trends that will be the main challenge for 2018. They are as follows; Evolution of Ransom ware- Ransom ware is one of the biggest challenges to cyber security. The following tends to disrupt the operations of the business organizations in a very hard way. This type of viruses is spread with the intention of demanding different things from the victim. This type of viruses is very difficult to remove from the system and can only be removed by means of paying or meeting the demands of the attacker. Most of the demands are in the form of financial transactions where amounts can shoot up to some hundreds and thousands of dollars (Graham, Olson Howard, 2016). The ransom ware attacks are growing at the most alarming rate which has risen from the crimes of the earlier year. Over 77% of the malicious items in the internet are malwares and any mistake from the part of the business organizations can land them into serious issues and can totally damage the operating system of their servers. However most of the organizations fails to understand the necessity of cy ber security and does not implement the necessary tools to counter those threats. This makes the task of the hackers easy and they are able to spread the virus and demand ransoms. More than 40% of the business organizations of the globe either do not possess any forms of disaster recovery strategies or the disaster recovery systems of their organization are outdated and of no use from new forms of attacks. Al Expansion- Artificial intelligence has been in the news for quite some time as it is being termed as the next big thing to fight the cyber attacks of all kinds. Experts in the business predict a rise in the investment of artificial intelligence in the globe to measure the incoming range of cyber attacks within the business. An amount of about $2.5 billion will be invested by the different companies on artificial intelligence to prevent the different kinds of cyber attacks. The development of robotics brings with it a number of different advantages in the business sector (Fielder et al., 2016). The first and foremost benefit of the organization is that they dont have to pay the robots for their work and so the business does not have to incur any expense on them except for maintaining them accordingly. Secondly the robotic technology works round the clock and all the year which is one of the major benefits of the business organizations. Timing is one of the most important considerat ions in the sector of the business as because it will be much easier for the organizations to fight the malicious items once the attack is on. On the other hand it will be an uphill task for the It experts to repair the damage once it is already done. Therefore the robotic technology is a game changer in the following sector and is surely the future of the business organizations which will assist them on their growth. Traditionally It experts came up with the solutions or failed to repair the damage as because it was not possible for them to work overtime and wait for different kinds of malicious attacks. The developers have a great understanding of the different facts and the programs of the organization and thus both robotics and It experts have to work hand in hand to counter the threats posed by the different malicious software. IoT Threats- The majority of the business organizations are active in the internet round the clock just to reach out to a large number of people to market their products and services. The introduction of the Internet of Things has no doubt changed the future of the world but has also different threats that need to be countered. The high range of interconnections in the complex world of Internet makes the organizations vulnerable to different kinds of threats that are present within this area. Major studies in the following area showed that over 70% of the devices used by the business organizations are susceptible to threats (Fielder et al., 2016). This happens just because of the presence of insecure web interfaces, data transfers and insufficient methods of communication. It also happens due to the lack of knowledge from the part of the users about the proper security measures to be implemented when using such devices. This is the ultimate truth that is supported by the facts of int er device communication. Thus the fact that accessing one device lets the user to handle a number of different devices increases the risk of the organization. Therefore it can be said that more the interconnectivity of devices, the more is the risk possessed. Therefore it is important for the business organizations to keep proper security measures like secured password, user verification codes, two factor authentication and other kinds of more complex security measures to avoid any risks. Block chain Revolution- The emergence of different forms of crypto currencies in the internet has been a revolution. These kinds of crypto currencies like Bit coin are build upon different block chains, the technical innovation and a decentralized and secure record of different transactions. It is quite difficult to predict the offerings of the development in the block chains. The business enterprises are thus concentrating on a number of different used cases which the block chain helps to enable from different medical records and other forms of decentralized access control (Graham, Olson Howard, 2016). Vulnerability of server less applications- Server less applications can easily invite the cyber attacks. The information of the customers in a business organization is at huge risk when it is being accessed from outside the server like locally or other devices. The information nowadays is generally stored in the cloud servers which are generally accessible from all kinds of devices and even the security is accessible from any kinds of devices in such cases. Therefore the hackers are easily able to control the different kinds of security measures taken by a customer of the business organization. The presence of server fewer applications are thus vulnerable to different attacks. The vulnerability of these kinds of attacks does not help the cause of the business and thus makes them prone to different threats (Knowles et al., 2015). Drone jacking- Organizations and consumers are using drones in new and innovative ways and the cybercriminals are ready for utilizing the golden opportunity to hijack the drones by hacking the technology (Liu et al., 2015). Reports have claimed that it is very easy to hack a toy drone and use it for criminal purposes by landing them over the roofs of different buildings and hacking the networking system. Social Engineering- Cyber security technology is becoming more advanced and complex with each passing days. The hackers thus are finding it tough to match the system technologies and hack them. However the presence of social engineering has given them another option to counter such complex technologies and hack the systems easily enough. The most popular types of example includes the likes of phishing technology which involves deceiving important data and information from the different individuals and use them to hack the system more easily. The anti phishing technologies must be installed by the different business organizations to make the system secure and safe from the hands of the hackers. Insider Threats- Business organizations are obviously vulnerable to cyber attacks from external threat but internal threats which occur from within the business can be the most dangerous and have a much greater impact on the operations of the business organizations. The security issue that arises from within the inside of the organization is very much harmful for the business as because it is totally unpredictable in nature and is hard to solve (Liu et al., 2015). Sixty percent of the data breaches occur as a result of different internal threats. More than half of the workforce of the organization has malicious intent and aims to disturb the proper working of the organization. There are also people who are not aware of the intents of the hackers and provides them different types of information unintentionally which leads to the occurrence of different kinds of threats. Machine Learning- The machine learning algorithms have been constantly helping the business organizations perform different types of complicated data analysis tasks on huge quantities of data at a large speed with a minimum manual input. According to, Nielsen (2015) this type of technology is used to determine the different kinds of frauds and can also determine the success rate of the different kinds of marketing campaigns and automated consumer product suggestions and many other types of innovative applications. Mobile Malware- The use of mobile devices is on a rise with the business organizations as because they are easy to carry and have the same kind of applications that are performed in a computer. However the cyber criminals have also targeted such mobile devices by creating different virus that are spread with the use of different kinds of applications. Different kinds of business organizations thus take the help of antivirus software to fight against such kinds of mobile malwares (Ray et al., 2014). There are also Trojans and mobile ransom ware that have the capability to disrupt the services of the organization. False advertisements and different feedbacks- The presence of false advertisements in the social media sites has been a problem for the consumers of the business organization as because the customers often falls into such traps set by the hackers. Fake advertisements are creating enough tensions for the business organizations as because they tend to disrupt both the operations and the reputation of the company. Absence of Firewall- The absence of firewall in most of the servers of different business organizations or the presence of outdated ones are a threat to the organization and a boon for the hackers of the organization (Ray et al., 2014). The adaption of a new firewall system that can counter all the threats will be useful for the business organization. Monitoring Cloud Configuration and Security- The monitoring of the cloud based software and the regular update and checking of the security of the entire system on a regular basis is utmost important for the management of the business organization to ensure the safety and integrity of the business organization (Shackleford, 2015). The regular update is required just to ensure that the system stays protected from the different kinds of threats possessed by the cyber threats. The hackers are involved in the creation of new forms of hacking technologies with the passage of each and every day. Therefore it is necessary for the business organizations to make sure that they regularly update the security system and provide the best technologies to stay risk free. High Impact Attacks- The biggest challenge is faced by the organization when a high impact attack tends to disturb the total working of the business organization. Viruses such as Wannacry, Shamoon v2 are really harmful and can cause extensive damage to the proper working of the business organization. Thus it is necessary for the enterprises to stay updated and ensure a risk free environment (Ray et al., 2014). Conclusion The following paper has discussed all the different elements and terms related to cyber security. The discussion, explanation and the proper recommendations to counter the different cyber security threats has made the project compact and flawless in nature. The brief yet compact description of cyber security, the importance of cyber security and the different threats and the challenges it provides has been well explained in the project. The analysis of the total work will help the readers to have a clear understanding of Cyber security and its importance to business organizations in the modern world.

Personal Statement from an Exchange Student free essay sample

With confused eyes and an empty stomach, I was to tell the lady in the cafeteria that I wanted a taco. It was a challenge for a student who just came to America three days ago, knowing limited English and nothing about American foodincluding â€Å"taco†. I told her I wanted the thing with meat and cheese, and some vegetables on top. She quickly gave me a cheeseburger and was ready to serve the next one. â€Å"SorryI don’t want this one† I blurted out before she moved her eyes away from me. She put her scoop down and removed the burger. †What do you want?† My face blushed like a guilty child, a quick glance of the waiting line made me sweat. I wished the school could assign the same food to everyone like schools in China so I would not have to suffer the embarrassment everyday. To try again, I held my hands like a cone, put it next to my mouth and pretended I was chewing on it. We will write a custom essay sample on Personal Statement from an Exchange Student or any similar topic specifically for you Do Not WasteYour Time HIRE WRITER Only 13.90 / page An †ah ha† smile suddenly brightened her face. â€Å"I got you!† She handed me a burrito. This was my first lunch at school, with all the frustration and an unwanted burrito. Living in the United States was completely new for me. The first obstacle in front of me was how to catch up with the curriculum. AP Chemistry, for example, made me really frustrated. I was totally lost in the different teaching style and the technical terms. After many tries, I found that an effective way to understand the curriculum was to interact with the class as much as possible. Sometimes I do make mistakes while speaking in front of class, but the key point is not to be afraid to express thoughts. Over time, I not only survived, but excelled. I ended up with all A’s on my grade report. Besides the curriculum, I also felt lost in the American students’ social life when I first came here. I had a hard time understanding my classmates’ conversations because they use a lot of slang, which I knew nothing about it. It took me a while to figure out what they were saying when I heard people sayâ€Å"Hey wazzup!†to me. So I tried to join as many extra-curricular activities as possible in order to learn how Americans socialize with each other. At the same time, I also shared Chinese culture with them, for example, participating in Girl Scouts and singing Beijing opera at the World Thinking Day in our town. Sharing and making friends brought me great happiness and a sense of self-actualization; I would like to carry on my passion to make my campus more diversified. Many people asked me why I chose to study in America. I told them because I want my life to be different and I have no fear to challenge. My determination has been developed from childhood when I traveled a lot to many countries in Europe, Southeast Asia with my parents. When most of my peers in China limit themselves to academics and let their parents make most decisions for them, I have already come across the ocean on my own and made great headway towards my future. America gives me greater expectations by showing me what I can really do. Before coming to America, I could never imagine myself writing a 10 page scientific paper in English; I would not believe my art work could be displayed and sold; and I would not even dream of standing on the stage for National Honor Society ceremonies to get the certificates of excellence. America makes these opportunities available to me! I think I have learned something important here about life. It is during the times you are far outside you r element that you experience yourself the most.

A Look At St Michael The Archangel Religion Essay Essays

A Look At St Michael The Archangel Religion Essay Essays A Look At St Michael The Archangel Religion Essay Essay A Look At St Michael The Archangel Religion Essay Essay The Holy Scriptures frequently speak of created intelligences, other than worlds, who worship God in Eden and act as His couriers and agents on Earth ( The Vatican ) . These existences are known as angels. Angels are mentioned in the Bible when they deliver messages, or appear in worlds dreams. Gabriel is the angel who appears most to worlds. Michael is called an archangel and a spirit prince. ( Student s Life Application Bible, Daniel 10:13, 31 ) . The archangel Michael is besides a saint and is revered global. What is an angel? The Vatican describes them as religious, non-corporeal existences ( The Vatican ) . This implies that angels are something wholly separate from human existences. But, angels are besides blessed with free will. Angels have a pick whether to follow God or non. God at the beginning of clip created from nil both animals together, the religious and the corporeal, that is, the angelic and the earthly, and therefore He created human nature as holding both, since it is made up of spirit and of organic structure ( The Vatican ) . Angels so, do non hold organic structures and are merely liquors. They can take the signifier of a human, as they frequently do when they are mentioned in the Bible. But it is non a true organic structure like ours. Worlds are both religious and material. We have a organic structure and we have a psyche. Angels live in Eden with God and harmonizing to St. Augustine, ever lay eyes on the face of my Father who is in Eden. St. Michael is called a n archangel, where does this topographic point him? There are categories of angels, harmonizing to Pope Gregory 1. This is the order he believed was to be the order of angels from highest rank to lowest: Seraphim, Cherubim, Thrones, Dominions, Principalities, Powers, Virtues, Archangels and Angels. This points out that angels are really are on the lowest graduated table of the heavenly hierarchy. Even Michael, who is an archangel, is non one of the higher ranks of angels. But, we do non hear of any types of angels specifically except for the four, or sometimes seven archangels. The four archangels are Michael, Gabriel, Raphael, and Uriel. ( Michael and All Angels ) Harmonizing to the Bible, an angel radius, I am Raphael, one of the seven angels who stand ready and enter before the glorification of the Lord. In Enoch: 20, the seven archangels are listed. And these are the names of the holy angels who watch: 1. Uriel, one of the sanctum angels, who is over the universe and over Tart arus. 2. Raphael, one of the sanctum angels, who is over the liquors of work forces. 3. Raguel, one of the holy angels who takes retribution on the universe of the leading lights. 4. Michael, one of the sanctum angels, to humor, he that is set over the best portion of world and over pandemonium. 5. Saraqael, one of the sanctum angels, who is set over the liquors, who sin in the spirit. 6. Gabriel, one of the sanctum angels, who is over Paradise and the snakes and the Cherubim. 7. Remiel, one of the sanctum angels, whom God set over those who rise. It is frequently said that these angels are associated with planets of the Solar system and specifically, Michael is paired with Saturn. ( Michael and all Angels ) . Michael the Archangel is mentioned merely four times in the Bible. He is mentioned in Revelations Then there was war in Eden. Michael and his angels fought against the firedrake and his angels. And the firedrake lost the conflict and he and his angels were forced out of Eden. This gives us the image that Michael is the 1 who physically throws Satan out of Eden, though it was God who banished him. Daniel provinces, But the prince of the land of Persia opposed me 21 yearss. So Michael, one of the main princes, came to assist me, and I left him there with the prince of the land of PersiaaˆÂ ¦.There is no 1 with me who contends against these princes except Michael, your prince ( Daniel 21:13,21 ) . Michael is twice called a prince in these Bible poetries. This gives us an image of Michael being exulted over others in Eden and on Earth. This is true, he is one of the darling angels and he is worshipped on Earth every bit good. Harmonizing to research, Michael is besides mentioned once more in Daniel At that clip Michael, the great prince, the defender of your people, shall originate. ( Daniel 12:1 ) . As you can see, in many of these Bible poetries Michael is called a spirit prince, prince, defender of the people. Michael, in a manner, is a prince. He fights for the protection of the reign of God, and he helps worlds in their times of demand. I admire St. Michael the Archangel because he is willing to put on the line everything for his Lord. Even though God does non like killing and war, he has a celestial ground forces and Michael is it s commanding officer. Michael battles for the one true thing he believes in. He is person I would draw a bead on to be like.

7 Most Common SAT Math Mistakes and How to Avoid Them

7 Most Common SAT Math Mistakes and How to Avoid Them SAT / ACT Prep Online Guides and Tips I spent several years tutoring students in SAT Math, and many found the section frustrating. The first test-takers for the new SAT in March felt the same. Some struggled because they felt their strong suit was English and were irkedby the content, mental math, and the pacing of SAT Math. Others found that although they considered themselvesexcellent math students, they struggled to finish and get the score they want. No matter what group theyfell into, students tended to make the same seven mistakes on the SAT Math section. In this guide, I’ll tell you what those mistakes are, give you examples, and let you know to avoid making these mistakes in the future. Mistake 1: You Didn’t Write Out All of the Steps Some students hate writing out their work for math problems.I know; I'mone of them.Trust me, while SAT Math problems may look simple since they only require you to know basic math topics (i.e. no advanced calculus), these problems are actually quite intricate, requiring you to go through many steps to get the correct answer. If you don’t write out all of these steps, you can accidentally end up with the wrong answer.This is especially important in the non-calculator section where you’re not able to rely on a calculator to help you find the correct answer. Together, we’ll work through this no-calculator SAT Math question and write out all of the steps: To determine what the price per pound of beef was when it was equal to the price per pound of chicken, you need to first find the value of $x$ (the number of weeks after July 1) when the two prices were equal.The prices were equal when $b=c$; that is, when $2.35+0.25x=1.75+0.40x$. $$2.35+0.25x=1.75+0.40x$$ You can find the value of x by reducing. $$2.35(−1.75)+0.25x=1.75(−1.75)+0.40x$$ $$0.6+0.25x=0.40x$$ $$0.6+0.25x(−0.25x)=0.40x(−0.25x)$$ $$0.60=0.15x$$ $$x={0.60}/{0.15}=4$$ Then, to determine b, the price per pound of beef, substitute 4 for $x$ in b=$2.35+0.25x$, which gives $b=2.35+0.25(4)=3.35$ dollars per pound. Therefore, D is the correct answer. When I initially attempted this problem, I didn't write anything down, and I accidentally added 1.75 to 2.35 instead of subtracting 1.75 from 2.35. Therefore, I got the wrong value for $x$, 27.33. Thankfully, when I plugged that into $b=2.35+0.25x$, I found thatmy answer wasn't one of the answer choices, so I caught my mistake. However, I'm lucky because I would have answered incorrectly otherwise. You don't want to miss questions because you didn’t write out all of the steps.This is arguably the easiest mistake to fix.Write out all your steps, and you’ll never accidentally get a question wrong because you skipped a step! Mistake 2: You Forgot Formulas The SAT gives you some formulas at the start of each Math section.However, the College Board doesn’t provide you with all of the formulas you need to know to answer every question in the SAT Math section. Luckily, here at PrepScholar, we’ve created a complete list of all the formulas you need to know for SAT Math.Create flashcards to help you memorize these formulas.However, memorizing alone is not enough.If you have the formulas memorized, but don’t know how to use the formulas, they’re useless to you. The best way to practice using formulas is to do as many SAT Math problems as you can. Let's work through this SAT Math question that you couldn’t answer without knowing formulas and how to apply them: If you didn't have your trigonometry formulas memorized (SOHCAHTOA), you would have no idea how to answer this question. It's impossible to answer this question without at least knowing the formulas for the sine and cosineof an angle. Memorizing formulas is not only necessary to answer certain questions correctly, but it can also be a time-saving shortcut. If you were a formula whiz and knewthe complementary angle relationship for sine and cosine, which is $sin(x °)=cos(90 °Ã¢Ë†â€™x °)$, you'd know immediately that the answer is $cos(90 °Ã¢Ë†â€™x °)={4}/{5}$ or $0.8$. However, if you didn't know that formula, but knew the sine and cosine formulas, you could stillsolve this problem by constructing a diagram using the given information.It’s a right triangle (which it has to be to use sine/cosine), and the sine of angle x is ${4}/{5}$. If $sin(x)={opposite side}/{hypotenuse}$,then the opposite side is 4 long and the hypotenuse is 5 long: Since two of the angles of the triangle are of measure $x$ and 90, the third angle must have the measure $180 °Ã¢Ë†â€™90 °Ã¢Ë†â€™x °=90 °Ã¢Ë†â€™x °$. If we know that $cosine={adjacent side}/{hypotenuse}$, then,using the figure, $cos(90 °Ã¢Ë†â€™x °)={4}/{5}$or $0.8$. SAT Math may make your brain hurt! Mistake 3: You Didn'tKnow Functions Functions are one of the trickiest topics in SAT Math.This is not because they'remore difficult than other topics, but rather students are simplyless familiar with functions than they are with other math concepts.The good news is that you'll easily master functions withpractice and familiarization. Let's work through thisSAT quadratic function question together: To figure outwhich answer choiceis the equation of the graph,you shouldstart by finding the y-intercept. Youcan see in this graph that the y-intercept is 2, which means you can eliminate C and E since C had a y-intercept of -2, and E has no y-intercept. The vertex of the graph is at $x=0$, so the function is not shifted to the right or left of the y-axis. This means that, in your quadratic equation $ax^2+bx+c$, your b value has to be 0. If it were anything other than 0, the graph would be shifted left or right of the y-axis. Let's look at the remaining answer choices, A, B, and D, to see which one had a b=0. A does so that might be the correct answer, but let's rule out B and D. Answer choices B and D are squaring expressions, so let's FOIL them in order to see the equation properly. Answer choice B gives us: $$y=(x+2)^2$$ $$y=(x+2)(x+2)$$ $$y=x^2+2x+2x+4$$ $$y=x^2+4x+4$$ This equation has b=4, not b=0, so it can't be the answer. You can also eliminate D; when foiled, it gives us: $$y=(x−2)^2$$ $$y=(x−2)(x−2)$$ $$y=x^2−4x+4, so b=-4$$ Therefore, A is the correct answer. If you're still struggling, check out our full guide to functions. Remember, you'll master functions with practice, so take as many SAT math practice tests as you can.

Mistake 4: You Panicked atan Unfamiliar Question Format SAT Math problems are often asked in strange waysthat you've never seen in math class. When confronted with these unfamiliar question formats, many students rush to move on to the next question thinking they'll come back to it, or they'll just try to guess the answer.Even though you’ve reviewed all of the math content areas and knew your stuff, you don't think you know how to answer the question. There is no easy solution to this issue.The only way to learn how to approach SAT Math questions is with practice. SAT Math questions are unlike the math questions you’re used to seeingin your math class, so to get familiar with the SAT Math question style, you should take as many practice SAT tests as you can. Let’s work through this convolutedSAT Math problem together: At first glance, this question looks overwhelming with a chart and a large paragraph. Don't let that scare you. Read carefully, and try to identify the important information as you read the question by circling or underling.Ask yourself: What am I solving for? What information am I given? How can I use this given information to find the solution? We're trying to find the probability that a right-handed student selected at random is female. We're told that there are 5 times as many right-handed females as there are left-handed females, and there are 9 times as many right-handed males as there are left-handed males. Also, we know the total number of left-handed students is 18, and the total number of right-handed students is 122. To solve this problem, you need to create a system of equations using two variables ($x$ and $y$) and the information you’re given in the question.Let $x$ be the number of left-handed female students and let $y$ be the number of left-handed male students. Using the information in the question, the number of right-handed female students will be $5x$ (since there are 5 times as many right-hand females as there are left-handed females) and the number of right-handed male students will be $9y$ (since there are 9 times as many right-hand males as there are left-handed males) . Since the total number of left-handed students is 18 and the total number of right-handed students is 122, the system of equations below must be true: $$x+y=18$$ $$5x+9y=122$$ When you solve this system of equations, you get $x=10$ and $y=8$.Thus, 50 of the 122 right-handed students are female.Therefore, the probability that a right-handed student selected at random is female is ${50}/{122}$, which to the nearest thousandth is $0.410$.The final answer is A. Don't run away from a weird question! Mistake 5: You Solved for the Wrong Value Because SAT Math questions can be convoluted, it's sometimes difficult to figure out what the question is asking you, which leads some students to solvefor the wrong value.Take for example this SAT Math question: This question throws a lot of numbers and letters at you. It gives you angle and side measures and mentions a similar triangle. Some students might accidentally solve forthe measure of the sides of DEF. Don't let the numbers and letters distract you. Make sure to identify what you're being asked: what is the valueof$sin F$? To find$sin F$, we need to start with thegiven information: Triangle ABC is a right triangle with right angle B.Therefore, AC is the hypotenuse of right triangle ABC, and AB and BC are the legs of right triangle ABC. According to the Pythagorean theorem, $$AB=√{(20^2)-(16^2)}=√{(400)-(256)}=√{144}=12$$ Since triangle DEF is similar to triangle ABC, with vertex F corresponding to vertex C, the measure of angle F equals the measure of angle C. Therefore, $sinF=sin C$, and $sinF={3}/{5}$.The final answer is ${3}/{5}$or $.6$. This problem has an easy fix: take the time to read the question fully, circle the important information, and make sure you know what you’rebeing asked before you start doing any work. I know you don’t have a lot of time on the SAT Math section (that was one of the chief complaints from the new SAT test-takers), but you need to read each question completely and make sure that you know what you’re being asked.You’ll get better at this with practice. Most SAT Math questions will have an answer choice that will seem correct if you misread the question.I know it’s rude and sneaky; the SAT is trying to tempt you to answer incorrectly.Don’t fall prey to the tricks! Read the question correctly, and you’ll be on the track to get the right answer! Mistake 6: You Used Your Calculator Incorrectly Calculators are both wonderful and horrible.You only get to use your calculator on one part of the SAT Math section, but for that part, you need to use your calculator carefully.When you’re rushing to answer SAT Math problems, you might accidentallytype the wrong number(s) into your calculator, leading you to the wrong answer. This isone of the better mistakes to make. Because if you type the wrong number(s) into your calculator, you’ll likely find no matching answer in the SAT answer choices, andyou’ll realize you made an error.However, even if you catch the error, you’ve still wasted valuable time that you could have been using to answer more SAT Math questions. Moral of the story: take the time to check that you’ve copied the numbers into your calculator correctly before running the calculation. Don't let your calculator become your enemy! Mistake 7: You Didn’t Pace Yourself With only 25 minutes to answer 20 questions in the no-calculator section and only 55 minutes to answer 30 questions in the calculator section, you need to learn to pace yourself.However, not every student should attempt the same pacing. You should plan your pacing based on your target SAT score. In both math sections, the questions progress from easy to hard and then re-set on the grid-in portion from easy to hard. No matter what your target score is, you should always attempt the easier questions: the first half of the multiple choice and grid-ins. If you're aiming for a Math section score above 700,then you're going to need to answer all or almost all of the 58 Math questions. That means you will need to get your pacing under oneminute per question for the easier questions to conserve time for the harder questions. If you're aiming for a Math section score below 700, then you can skip some questions.Focusyour time on trying to answer the easier questions correctly (the beginning questions of the multiple-choice and grid-ins).Consider bubbling in a random letterfor the harder questions since there is nopenalty for guessing. Note: if you use this strategy, make sure that you’re answering enough questions to reachyour target score.No one is perfect, so count on answering a few questions incorrectly. For example, if you’re aiming for 600 in Math, then you shouldattempt at least 45 questions before bubblingin random answers for the other 13 questions. That way, if you answer five of the 45 incorrectly, you can still get 600. Give yourself acushion. To really master yourpacing on the SAT Math section, you need to take a lot of practice tests under realistic testing conditions.For a more in-depth explanation on pacing, check out our guide to help you beat the clock and maximize your SAT math score.

Economic Factors Assignment Example | Topics and Well Written Essays - 1000 words

Economic Factors - Assignment Example Industry A: 20 firms and a Concentration Ratio (CR) of 30% Name and some of the industry's characteristics An industry with 20 firms and a CR of 30% is called a low concentration industry. This is a type of industry in which its four largest firms control less than 50% of its market. According to Ruffinand Gregory (2000), this type of industry is monopolistically competitive and the market control gained by its four largest firms/industries is moderate. There are many firms producing a similar product. Prices are set through a contestable market model hence the decisions of one firm are not influenced by the decisions of another firm. The above is supported by the fact that in this industry, the key to success is the ability to offer products at a lower price (Weiss, 1989). Even of the sellers were few or even one, they would act as if they were many. Entry and exit from the industry is costless and new entrants are mainly attracted into the industry if a possession of market power i f profitable. The pressures of competition help to prevent monopoly and keep the industry operating at a prices and outputs that are competitive. Expected long-run adjustments in case there was an increased demand for a product that pushed up the price of goods When there is an increase in demand of a product that in turn leads to an increase in its price, all the 20 firms in the industry are going to make positive profits and prosper. In the short-run, marginal costs and marginal revenue will be equal indicating an equilibrium or profit maximization. In the long-run, firms will alter the scale of product and leave or enter the industry. Other firms who want to take advantage of the profit will enter the industry leading to a rise in supply of the product. This will push the market prices of the product down to the long-run equilibrium. What the anticipated adjustment process imply about the CR for the industry The above-mentioned anticipated adjustments imply that there is a relati onship between the CR of the industry and the properties of the industry. For example, when the CR is low as in this case, monopolistic competition takes place resulting to the market exhibiting elements of both monopoly and perfect competition. The reason behind this is that since the industry is monopolistically competitive, each of its existing firms has the power to set prices. They will compete for a control of the market share by lowering their prices and in the end, many of them will charge the long-equilibrium price. This establishes an equilibrium and eliminates incentives for entry. In other words, a low CR eliminates temporary rise in prices and restores the economy to a long-run equilibrium level, a characteristic of a competitive market. Therefore, it is true to say that the lower the CR, the higher the level of competition of the market. Industry B: 20 firms and a Concentration Ratio (CR) of 80% Name and some of the industry's characteristics An industry having 20 firm s and a CR of 80% is called a high concentration industry. 20 firms and a CR of 80% indicate a highly oligopolistic industry. In this type of industry, a significant level of market control is under the power of four of its largest firms (Ruffinand, 2000). The market is dominated by few firms who sell slightly differentiated

Social issues in canada Essay Example | Topics and Well Written Essays - 500 words - 1

Social issues in canada - Essay Example As the nation has a lot of Catholic individuals, any kind of abortion was not tolerated. From 1969, abortion was permitted in the event when the life of a mother is said to be at risk. Illegal abortions were still done and in 1988, Dr. Henry Morgentaler, an abortionist was faced with abortion charges. Finally, the court ruled that the present abortion regulations in Canada epitomized an unconstitutional burden on women rights. This made the law to be upended (McCullough, 2014). Even though the Canadian Supreme Court allowed for other limits on abortion, the government of Canada has never approved any of the limits. Women in Canada are at liberty to abort and it is seen to be a degree of laxity that has not been seen in any part of the western world. The Canadian health care system is seen to be functioning properly and liked by most individuals for the services they provide. Since 1960s, the Canadian government started a slow process of removing out the profit making health clinics, hospitals and insurance. They were later replaced with universal, new and health care system funded by the government. Currently, every individual in Canada is offered comprehensive health insurance without requesting. This is done by the use of public health coverage plans that different provincial governments run (McCullough, 2014). It means that every Canadian individual does not need to pay for his/her medical bills or depend on their employers for any health insurance. A small amount on monthly premiums is charged by the government while it steps in to clear the majority of the bill for operations, check-ups and exams. It is not easy to maintain a health care system. Currently, many Canadian individuals need to purchase supplementary private health insurance required in paying for eye examinations, operations termed as non-essential by the government and dentist examinations. Likewise, hospitals in Canada mostly have a lot of patients because they are accessed easily. This
