Exam Grade Calculation


Q. 22 Suppose a professor counts the final exam as being equal to each of the other tests in her course, and she will also change the lowest test score to match the final exam score if the final exam score is higher. If a student’s four test scores are 83, 67, 52, and 90, what is the lowest score the student can earn on the final exam and still obtain at least an 80 average for the course?

 
Sum of Scores including last score = 83 + 67 + x + 90 + x = 2x + 240

Equation will be

(2x + 240 ) / 5 = 80

 
2x + 240 = 400

2x = 400 – 240

2x = 160

X = 80

Student can earn a lowest score of 80 and to keep the average at 80.

Grade Calculation


Q. 21. To earn an A in a course, a student must get at least a 90 average on four tests and a final exam, with the final exam weighted twice that of any one test. If the four test scores are 93, 69, 89, and 97, what is the lowest score the student can earn on the final exam and still get an A in the course?

(93 + 69 + 89 + 97 + 2x ) / 6 = 90


348 + 2x = 90 * 6


Therefore x = 96

Student needs a lowest grade of 96 to get at least 90 average in all subjects

Calculating simple list price

A wholesaler wants to establish a list price for an item so that his selling price gives a trade discount of 10% for the list price. If he makes a mark up of 20% of this selling price and if his cost is $160 what list price should be established. 

Selling price = list price - list price * 10%

Cost = 160

Also selling price = 160 + 160 * 20%
SP = 192

So we can solve the first eq:

Sp = Lp - Lp * 10/100

Sp = Lp ( 1 - 1/10)

192 = Lp ( 9/10)

Lp = 1920/9 = 213.333

The End of Poverty - Must Watch

Global poverty did not just happen. It began with military conquest, slavery and colonization that resulted in the seizure of land, minerals and forced labor. Today, the problem persists because of unfair debt, trade and tax policies — in other words, wealthy countries taking advantage of poor, developing countries. Renowned actor and activist, Martin Sheen, narrates THE END OF POVERTY?, a feature-length documentary directed by award-winning director, Philippe Diaz, which explains how today's financial crisis is a direct consequence of these unchallenged policies that have lasted centuries. Consider that 20% of the planet's population uses 80% of its resources and consumes 30% more than the planet can regenerate. At this rate, to maintain our lifestyle means more and more people will sink below the poverty line. Filmed in the slums of Africa and the barrios of Latin America, THE END OF POVERTY? features expert insights from: Nobel prize winners in Economics, Amartya Sen and Joseph Stiglitz; acclaimed authors Susan George, Eric Toussaint, John Perkins, Chalmers Johnson; university professors William Easterly and Michael Watts; government ministers such as Bolivia's Vice President Alvaro Garcia Linera and the leaders of social movements in Brazil, Venezuela, Kenya and Tanzania. It is produced by Cinema Libre Studio in collaboration with the Robert Schalkenbach Foundation. Can we really end poverty within our current economic system? Think again.

Estoy estudiando español

I'm trying to learn some spanish using the Rosetta Stone software. It's pretty good and interactive. Software helps you learn the language very easily and it does not at all feel like work (trabajo).

It's going to help me in work and probably in other situations as well.

Facebook should have a 'Not Like' / 'Thumbs Down' Button too ..


  All popular websites have it. It's obvious if you can like stuff then you will dislike stuff as well. Every now and then people post stuff on facebook that you don't really like. I suppose their idea of not liking something is just not to click 'the like' button. But that is not enough, sometimes you want to express your feelings and a 'not like' or 'dislike' button would come in extra handy.

Wow! My Internet was down!

It's been down for almost two weeks. I just got it working today. I kept on complaining  and complaining and they never fixed it. Turns out that my cable wire was broken somewhere inside my home! *Dumb*
