A bank's loan officer rates applicants for credit. The ratings are normally distributed with a mean of 200 and a standard deviation of 50. If an applicant is randomly selected, find the probability of a rating that is between 170 and 220. Your answer should be a decimal rounded to the fourth decimal place.

0.3811 is the probability that a randomly selected applicant will have a rating between 170 and 220.

Step-by-step explanation:

We are given the following information in the question:

Mean, μ = 200

Standard Deviation, σ = 50

We are given that the distribution of ratings is a bell shaped distribution that is a normal distribution.

Formula:

P(rating is between 170 and 220)

0.3811 is the probability that a randomly selected applicant will have a rating between 170 and 220.

heyyy

step-by-step explanation:

the given 6 = w/p is equivalent to 6p = w, where w is the total area of the walls and p is the area covered by a single can of paint.

knowing that 6 cans of paint will be needed, 6p = w becomes 6(6) = w = 36.   this tells us that the total area to be painted is 36 square units.
