What number represents the median? *

49
50
53
60

Median = 51.50

Step-by-step explanation:

By definition, the median is the middle number in a given set of listed numbers arranged in ascending or descending order.

There are a total of 4 numbers listed in ascending order.  Given that 4 is an even number, then it implies that there are two values in the middle, represented by 50 and 53. Therefore, we can take the average of those two numbers to get the median:

Median =

  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).
