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:

Answer:
15h
Step-by-step explanation
-5g plus 15h is 10 h minus 25 is 15h
Ok so the equation would be
amount = number of bacteria originaly *optional* × 2^(number of minutes divided by 10)
It's the number of minutes divided by 10 because it doubles every 10 minutes.
So if it took two hours for all of it to fill, it would've been 120 minutes so 12 10 minutes.
2^12
So half of that would be 60
I think it takes an hour if you divide it --- the rest is just extra calculation
Take the totally needed to buy it, put the amount you have and then add but substitute for a variable the amount needed.
