Answer:
C. FE and ED
Step-by-step explanation:
The question is asking what are the sides of angle E. I've marked angle E along with its sides in the attached picture.
One side of the angle E has to be ED.
However we have multiple options for the other side. It can be called FE, CE or BE.
So the answers could be any of:
- ED and FE
- ED and CE
- ED and BE
The option that has one of the possible answers is option C: FE and ED.
Answer:
48.48%
Step-by-step explanation:
Let's assume that there is a number N of women.
32% of these are smokers, then there are 0.32*N smokers
then 68% of these are non-smokers, then there are 0.68*N non-smokers.
Let's assume that the probability of having a ectopic pregnancy for a non-smoker is p (and the probability for a smoker will be 2*p)
Then the number of women with an ectopic pregnancy that are non-smokers is:
p*0.68*N
The number of women with an ectopic pregnancy that are smokers is:
2*p*0.32*N
Then the total number of women with an ectopic pregnancy will be:
p*0.68*N + 2*p*0.32*N
The percentage of women having an ectopic pregnancy that are smokers is equal to the quotient between the number of women with an ectopic pregnancy that are smokers and the total number of women with an ectopic pregnancy, all that times 100%.
The percentage is:
Taking p and N as common factors, we get:
Then we get:
