Bruce is going to call one person from his contacts at random. he has 25 total contacts. 20 of those contacts are from his neighborhood. what is the chance he doesn't call someone from his neighborhood

1/5 is the chance to call from his neighborhood.

Step-by-step explanation:

Bruce is going to call a person from his contacts at random.

Out of 25 contacts 20 contacts were from his neighborhood.

Therefore chance to call someone from his neighborhood is 20/25 = 4/5

Now chance that he doesn't call from neighborhood will be = 1 - chance to call from his neighborhood = 1 - (4/5) = 1/5.

1/5 is the answer.

  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).

this is not the answer this is just a question. is this middle school math?
