The formula for volume always involves three dimensions.

In this case, the volume of a cube is $V=s^3$ , where $s$ is the side length of the cube.

To solve for that side length, you'd need to use a cube root.

Answer:

- 7

Step-by-step explanation:

The average rate of change of f(x) in the closed interval [ a, b ] is

$\frac{f(b)-f(a)}{b-a}$

Here [ a, b ] = [ - 5, - 2 ]

f(b) = f(- 2) = (- 2)² - 4 = 4 - 4 = 0

f(a) = f(- 5) = (- 5)² - 4 = 25 - 4 = 21, thus

average rate of change = $\frac{0-21}{-2-(-5)}$ = $\frac{-21}{3}$ = - 7

"More than 60% of the students scored below the mean on the last test." Can this statement be true? Why or why not?

Lelu [443]

The mean is the average of a set of numbers.

So if the remaining 40% of students score 100 points, and the 60% score like 50 points, then the mean would still be 70 points because of the 40% of students that scored super high.

So yes, it can be true.
