In a class of 30 students, there are 18 boys and 12 girls. What is the ratio of girls to boys?

3:2

Step-by-step explanation

18:12, divide both by 6, 18/6=3, 12/6=2, ratio simplified is 3:2

Step-by-step explanation:

12:18

2:3

  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).

step-by-step explanation:

compare
