Step-by-step explanation:

The percentages total 100%, so the missing percentage is

  100% - 60% = 40%

The numbers on the number lines are proportional, so now you can write ...

  ?/100% = 28/40% . . . . . . ? total students

Multiplying by 100% gives ...

 ? = 28/0.4 = 70 . . . . . total students

Then the 60% portion of students can be found two ways:

  60% × 70 = 42 students . . . . 60% of students

  70 -28 = 42 students

  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).
