The distribution of cholesterol levels in teenage boys is approximately normal with and (source: u. s. national center for health statistics). levels above 200 warrant attention. find the probability that a teenage boy has a cholesterol level greater than 225.

0.033 is the probability that a teenage boy has a cholesterol level greater than 225.

Step-by-step explanation:

The following information is missing in the question:

Mean, μ = 170

Standard Deviation, σ = 30

Using the given information, we may solve the question as:

We are given that the distribution of distribution of cholesterol levels in teenage boys is a bell shaped distribution that is a normal distribution.

Formula:

a) P( cholesterol level greater than 225)

P(x > 225)

Calculation the value from standard normal z table, we have,  

0.033 is the probability that a teenage boy has a cholesterol level greater than 225.

the smallest possible measurement of the width is 14 feet

step-by-step explanation:

let's assume length of parallelogram is 'l'

width of parallelogram is 'w'

the perimeter of a parallelogram must be no less than 40 feet

so, we get

we are given

length of parallelogram is 6 feet

so,

l=6

we can plug it

now, we can solve for w

subtract both sides by 12

divide both sides by 2

and we get

so,

the smallest possible measurement of the width is 14 feet

idk lol xd
