Help pls I need to study for a quiz

it's a because 120 is the sample size and that's almost 1/3 of the school so you time 36 by 3 it's close to a

-7/8

step-by-step explanation:

instead of subtracting you add the -6/8 and -1/8

set each factor equal to 0

4x-3 = 0

2x-1 = 0

solve for x.

4x-3=0

4x=3

x= 3/4

solve for x. 

2x-1= 0

2x= 1

x= 1/2

eventually after a few more steps, your answer should be 1/2 is less than or equal to x and 3/4 is greater than or equal to x
