The answers are:
C. If 5x + 10 =20 then x =2
D. If 6x-12=48, then x=10
F. If 8x(x-4)=32, then x=8

Answer:
10% probability that a given class period runs between 51.25 and 51.75 minutes.
Step-by-step explanation:
An uniform probability is a case of probability in which each outcome is equally as likely.
For this situation, we have a lower limit of the distribution that we call a and an upper limit that we call b.
The probability of finding a value X between c and d, d greater than c, is given by the following formula:

Uniformly distributed between 49 and 54 minutes
This means that 
Find the probability that a given class period runs between 51.25 and 51.75 minutes.

10% probability that a given class period runs between 51.25 and 51.75 minutes.
