7m - 3m + 5 = 45
4m + 5 = 45
45-5 = 40
4m = 40
40/4
m = 10 minutes

Answer:
The probability of selecting a class that runs between 50.2550.25 and 51.2551.25 minutes is 0.10
Step-by-step explanation:
The Uniform Distribution, also known as Rectangular Distribution, is a type of Continuous Probability Distribution. It has a continuous random variable restricted to a finite interval and its probability function has a constant density during this interval.
The formula of probability if given by:
f(x)=

In this exercise a= 46.0 and b= 56.0
The probability of selecting a class that runs between 50.2550.25 and 51.2551.25 minutes is:

3 and 2/3 hours.
Multiply the number of hours Dominic spent by the scale factor.
