Cholesterol levels for women aged 20 to 34 follow an approximately normal distribution
with mean 185 milligrams per deciliter (mg/dl). Women with cholesterol levels above 220 mg/dl are con-
sidered to have high cholesterol and about 18.5% of women fall into this category. What is the standard
deviation of the distribution of cholesterol levels for women aged 20 to 34?

the temperature will be -18 just do 62 + (-40) + (-40)

step-by-step explanation:

the correct option is 2.

step-by-step explanation:

according to the given information triangle abc is a right angle triangle with right angle at a. segment ab is 5 and segment ac is 7. point d is on segment bc and angles adb and adc are right angles.

it is given that triangles abd, cad, and cba are similar.

two triangles are similar if their corresponding sides are proportional.

in triangle cba, using pythagoras theorem

                      )

triangle abd and cba are similar,

                            (2)

triangle cad and cba are similar,

                      )

using (1), (2) and (3), we get

hence proved.

therefore option 2 is correct.

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
