Zack is taking a test in which he answers questions at a rate of 1/3 question per minute. How many questions can he answer in 6 minutes? 6
2 3
18

He can answer 2 questions in 6 minutes.

Step-by-step explanation:

This question can be solved by proportions, using a rule of three.

Each minute, Zack solves 1/3 of a question. How many questions can he solve in 6 minutes?

1 minute - 1/3 questions

6 minutes - x questions

He can answer 2 questions in 6 minutes.

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).
