The average employee in the u. s.a. spends μ = 23 minutes commuting to work each day. assume that the distribution of commute times is normal with a standard deviation of σ = 8 minutes.
(a) what proportion of u. s. employees spend less than 15 minutes a day commuting?
(b) what is the probability of randomly selecting an employee who spends more than 35 minutes commuting each day?

you probably already have the answer but anyways it's b. 15.0

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
