A spinner contains the numbers 1 through 60. What is the probability that the spinner will land on a number that is not a multiple of 13? Give your answer as a fraction.

56/60 or 14/15

Step-by-step explanation:

The only multiples of 13 between 1 and 60 are:

13, 26, 39, and 52.

Excluding those numbers from the list leaves us with 56 numbers. Therefore, the probability of landing on a number that is not a multiple of 13 is 56/60 or 14/15 if reduced.

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13
