Imagine a college where say 2000 students are taking an intro stat course. Imagine from historical data, that student scores of a final exam can be viewed as approximately normal with a mean of 70 and a sd of 10. Suppose an A grade is considered to be 90 or higher. Now imagine a SRS of 100 students is selected from the group of 2000 students, where we then compute the sample mean of these 100 students.

42 inches then 10 1/2 deep

1 number

if we use a graphing calculator, there is only one such number that satisfies the conclusion of the mean value theorem, that is, a number such that

where the right-hand side is the average rate of change of f on the interval [0.5,0.75], which is the slope of the secant line.

in the attached graph, the black line is the secant line which has its slope as the average rate of change of f on [0.5,0.75], while the orange line is the only tangent line to the graph of f in the interval that satisfies the mvt conclusion.

the answer is b: 18

step-by-step explanation:

use the pythagorean theorem to .

a^2+b^2=c^2

plug 18 for "r"

the 2 legs are 18 and 24

18^2+24^2=c^2

324+576=c^2

900=c^2

c=30

30-12=18

18 is the radius
