11.) The physics class took two tests. On the first test, the mean score was 72 with a standard deviation of 5. On the second test, the mean score was 80 with a standard deviation of 6. Cindy made an 82 on the first test and an 87 on the second. On which test did she do better relative to the rest of the class?

step-by-step explanation:

(f - g)(x) = 5x^3 - 3

step-by-step explanation:

rearrange these functions vertically, with like terms in separate columns:

f(x) = 5x^3 - 2

g(x) =         +1

now subtract, column by column:

(f - g)(x) = 5x^3 - 3

the simplified form is

step-by-step explanation:

we want to simplify the expression,

let us change the middle bar to a normal division sign to obtain,

we multiply the first fraction by the reciprocal of the second fraction to obtain,

we factor to obtain,

we cancel the common factors to get,

we simplify to get,

the correct answer is b
