Answer:
Step-by-step explanation:
The question above is answered below.
Rewriting the expression above without parentheses is done by simply removing the parentheses using the negative sign. Note that the signs of the constant (5) and term (8m) in the expression are positive (+). Thus, using the negative sign to remove the parentheses will be done using the arithmetic signs rule: - × + = -, that is, minus times plus equals minus; such that - × +5 = -5 and - × +8m = -8m. Therefore,
In case the expression is to be evaluated, the result will be:
14m - 5 - 8m
Rearrange the terms
14m - 8m - 5
6m - 5

Using the uniform distribution, it is found that there is a 0.3 = 30% probability that Samantha has to wait less than 4.5 minutes to catch the bus.
<h3>What is the uniform probability distribution?</h3>It is a distribution with two bounds, a and b, in which each outcome is equally as likely.
The probability of finding a value of at lower than x is:
In this problem, the time is uniformly distributed between 0 and 15 minutes, hence the bounds are a = 0 and b = 15.
