Abag of marbles is full with 20 marbles, 12 of which are yellow. how many are not yellow? a. the number of yellow marbles b. the total number of marbles c. the number of marbles that are not yellow

12 yellow marbles of 20 marbles total leaves 20-12 = 8 non-yellow marbles.

C. If there are 20 marbles and 12 are yellow, then the number of non-yellow marbles is:

20 - 12 = 8

There are 8 non-yellow marbles.

Hope it helped,

Happy homework/ study/ exam!

  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).
