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.

x= -3 and

step-by-step explanation:

to find the roots of a cubic, use division or factoring to find the factors then set equal to 0. as this is a difference of cubes, it factors into

where a is the cube root of .

here   this is 27 and the cube root of 27 is 3. so we write using the form:

.

set each factor to 0 and solve for x.

x-3=0

x=3

the quadratic expression does not factor and must be solved using the quadratic formula.

where a = 1, b=3, and c=9

this cubic has two complex roots.

c

step-by-step explanation:

it would be see because your formula is f(x)=6x, so 6 times 1 is 6 and you go on and the best answer is c.
