To find the constant of proportionality<span> here let's look at the </span>equation<span> of a line for a straight graph that passes through the origin. y is your vertical y-value for any given point on the line, x is your horizontal x-value for any given point on the line, and m is the slope.</span>
7/16 + 3/8 + Blank = 1
7/16 + 6/16 + 3/16 = 1
convert 3/8 to 6/16 then add 7+6 which = 13
that would be 13/16 then figure out that 13+3 =16 so 13/16+3/16= 16/16 or 1
Answer:
Step-by-step explanation:
r = Radius of semicircle = 
Area of semicircle is given by
The area of the semicircle is 
.
All the probabilities are given for the three different scenarios in men and women: people who smoke, people who develop lung cancer, and people who develop lung cancer who are also smokers. Then, these are even classified in terms of gender.
But the final question only has to do with men who are smokers that develop lung cancer. So, I think all the other data are only there for the purpose of red herring. The answer is already there, but you just have to find it among the others. First, you ignore all the probabilities involving women because we only want the men. Then, you find the probability of men that have lung cancer being smokers. The answer is 90%.
