2/9 of the students in a school are in sixth grade. a. How many sixth graders are there if the school has
90 students?

b. How many sixth graders are there if the school has
27 students?

a=20

b=6

Step-by-step explanation:

you divide the number of students by 9 then add that number to itself and there's your answer

A. 20

B. 6

C.189

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).

good luck on your studies! : )
