PLEASE HELP!! Given the mean of a normally distributed data set is 25, with a standard deviation of 5, what percent of the population falls between 15 and 30?

A) .5
B) 41.5
C) 61.5
D) 81.5

its B.) and how the heck do i have -156 points on

Step-by-step explanation:

(2,20) means that the 2 is 2 hours and 20 is 20$. so there both 20$ for 2 hours only the same price. like it says. so, the dunk tank and the bounce house are the same price (20$) for the same amount of time (2 hours).

hope i
