### Probability

(a) Proportion of students that got a B or higher. Add the percentages or decimals for X=3, 3.3, 3.7, 4: 16+6+7+19=48% or 0.48. (b) Grade poorer than B- is when X<2.7,  P(X<2.7). Add the percentages or decimals for X=0.0, 0.7, 1.0, ...  2.3: 3+4+5+3+5+15+5=40% or 0.40. The 4-point scale is just a convenient way of converting the grade letters into numbers. This means that results are easier to computerise, because computers are better working with numbers than letters; whereas most humans find the grade letters have more meaning to them. The other thing students may find confusing is the function P, but it's only shorthand for using the words "the probability of" then parenthesising the particulars, X is equal to, greater than, less than, etc., where X is the numerical value associated with the grade. This question is testing your understanding of how to convert ordinary words into mathematical terms, and vice versa. So don't let this sort of question put you off. It's really simpler than you think! For example, P(X<2.7)=0.40 is so much shorter than using a lot of words, and yet it means the same thing.

### 30 questions worth 3 points i got 2.4 percent correct whats my grade

### average of the class grades is 87% on 60 questions what is the average of right questions?

quesshuns mae all be rite...yu want % av ansers that R rite 87% av 60 =0.87*60=52

In words the question is: what is five sixths plus three sixths? If I ask you: what is five apples plus three apples you'd answer: eight apples. So 5/6 + 3/6 is 8/6. But 8 and 6 have a common factor 2, 4*2/3*2. 2/2=1 so we're left with 4/3. If you want to, you can divide 3 into 4 to give you 1 and 1/3.

### which one is better to measure the center of a data, the mean or median?

"Better" is a funny word because, by itself, it doesn't tell us anything.  The problem is "better" depends on the goal you're trying to achieve and, without knowing that goal, we can't say which is better. Let's say you have a jet and you want to calculate how much the passengers are going to weigh, in order to know how much fuel you need.  In that case the average weight of the passengers would be more useful. Let's say you have a tutoring service and you want to help students with grades in the bottom 50%.  It doesn't matter what the actual grades are.  You're just making a list of students, sorted by grade, then helping the bottom half of that list.  In that case the median grade would be more useful. . Note:  This is why arguing about which thing (ex: a sports team) is "better" is meaningless.  One could argue about which team has a better winning percentage, but without an actual numerical comparison, each person is really arguing about which team they themselves like better.  The "better" team is different for each person and each person is making a true statement, so the question of which is right and which is wrong has no meaning.  The question of which food, or which dress, or which political candidate is better is meaningless unless a particular goal or criteria with a testable number is identified first.

### the professor breaks 25 students up into five (5) study groups and graded on a bell-shaped curve.

There's many things to ask concerning your problem like "What's your question?" Other important questions include "are the groups even?"  "Is the bell curve lopsided?"  "Did each student in a group recieve the same grade?"  "What is the standard deviation for the bell curve?" At first glance, I'd say one group failed, three passed, and one group aced the test.

### Can you show me how to solve these?

1) -3.66x = -20.52x - 1.7  to nearest tenth add 20.52x to both sides: 20.52x - 3.66x = -1.7 16.86x = -1.7 divide both sides by 16.86: x = -1.7/16.86 = -0.1  to nearest tenth   2) 17x - 19 = 106  to nearest hundredth add 19 to both sides: 17x = 125 divide both sides by 17: x = 125/17 = 7.35 to nearest hundredth   3) -36 - 19x = 14  to nearest tenth add 36 to both sides: -19x = 50 divide both sides by -19: x = 50/-19 = -2.6 to nearest tenth   4) 14x - 8 = -33 + 2x   to nearest hundredth add 8 to both sides: 14x = -25 + 2x subtract 2x from both sides: 12x = -25 divide both sides by 12: x = -25/12 = -2.08 to nearest hundredth   5) -12.6 + 10.5x = 8x - 7.2  to nearest tenth add 12.6 to both sides: 10.5x = 8x + 5.4 subtract 8x from both sides: 2.5x = 5.4 divide both sides by 2.5: x = 5.4/2.5 = 2.2 to nearest tenth
