The box plot represents the amount of time 15 pet owners spend exercising their pets each day.

Answer: False

Step-by-step explanation: To find the mean time add all the times and divide by the amount of times you have, which is 9.

0 + 15 + 30 + 90 + 105 + 120 + 45 + 60 + 75 = 540 total minutes spent.

Now divide 540 by 9 to get the mean time. 540 divided by 9 = 60.

So the mean is 60 minutes, not 75 minutes.

Therefore the statement below is False.

If AX) = x2 + 2x + 3, what is the average rate of change of AX) over the interval (-4, 6]? OA 51 B. 40 OC. 31 OD 20 OE 4

Yuki888 [10]

Answer:

Step-by-step explanation:

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

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

Here [ a, b ] = [ - 4, 6 ] , then

f(b) = f(6) = 6² + 2(6) + 3 = 36 + 12 + 3 = 51

f(a) = f(- 4) = (- 4)² + 2(- 4) + 3 = 16 - 8 + 3 = 11 , thus

average rate of change = $\frac{51-11}{6-(-4)}$ = $\frac{40}{10}$ = 4 → E
