Johnny has his own company doing yard work. His sales are normally distributed with a mean of $450 a day with a standard deviation of $110. What is the probability that he will make greater than $230?

step-by-step explanation:

rectangles are made up of 4 right angles, which means that a side and a base meet perpendicular to one another.   their slopes then have to reflect perpendicular slopes.   perpendicular slopes are opposite reciprocals of one another.   for example, if the slope of one line is +2/3, then the perpendicular slope to that would be -3/2.   so we look for that combination in our choices.

all of them satisfy that condition (so what's the question, i guess? )

i don't think there is enough

to be honest i don't know but i need points so

oh

nu stiu chiar nu stiu sa o fac
