Here is a list of numbers:
-20, -6, -12, 18, 14, 18, -15,-9,-4,-10
State the median.

-7.5

Step-by-step explanation:

Put all the numbers in order (least to greatest)

-20, -15, -12, -10, -9, -6, -4, 14, 18, 18

Find the number in the middle

-9 and -6

Add -9 and -6 together and divide by 2 to get median.

-7.5

  b.   the average rate of change of f(x) is less than the average rate of change of g(x).

step-by-step explanation:

since the length of the interval is the same in each case, we only need to compare the change in y-value to see which is greater.

so the change in y-value for function f is (6 )) = 9.

the table tells us

so the change in y-value for function g is (31 -1) = 30.

the change in y-value of f(x) on the interval is less than the change in y-value of g(x) on the same interval, so the average rate of change of f(x) is less than the average rate of change of g(x).
