What is the probability that a cuatomer will not pick a drama

80%

Step-by-step explanation:

add all number and you get 125

divide drama 25 by 125

you get 1/5

so 4/5 of the people will not pick drama

4/5 = .80

10

step-by-step explanation:

7+3=10

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.
