What is the mean and MAD of 12,16,15,11,31

The mean is 17.

Step-by-step explanation:

The mean is 17

and the MAD is 5.6

Step-by-step explanation:

  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).

x> 6

step-by-step explanation:

8x+8> 7x+14

8x-7x> 14-8

x> 6
