This table gives information from a survey about cholesterol levels in men and women over 40 years old. high cholesterol normal cholesterol men 27 23 women 21 29 the relative frequency of people with high cholesterol who are women is 0.420.440.530.56. the relative frequency of men who have normal cholesterol levels is

a) The table shows 27+21 = 48 people with high cholesterol. Of those, 21 are women, so the relative frequence is 21/48 = 0.4375 ≈ 0.44

b) This question is ambiguous. If we assume it is asking the relative frequency of normal cholesterol among people who are men, that is 23 men out of 27+23 = 50 men surveyed. The relative frequency is 23/50 = 0.46

the answer is a

step-by-step explanation:

step-by-step explanation:

i think something is missing in your question because y-1=(x-12) would not pass through the point (-4,-3). because if you replace x by -4 your are supposed to find y=-3 which is not the case her. if you replace x by -4 you find =-15.

i assume the right equation is y-1=1/4*(x-12) because this one is passing through both your points (if you are interested to know how i found that out i can tell you).

in this equation if i replace x by -4 i find y=-3 and if i replace x by 12, i find y=1 so the line representing this equation is passing through those 2 points.

then the standard form of the equation is finding an expression of y in function of x

y-1=1/4*(x-12)

y=x/4-3+1

y=x/4-2

hope that .

do you confirm there was a mistake in the question?
