Answer:So, since it is continuously, we need to think of PERT
A=P\times e^{rt}
So, we just plug our numbers in to solve for T
8000=4000e^{.07t}\\\ln(8000)=\ln(4000e^{.07t})\\\ln(8000) = \ln(4000) + \ln(e^{.07t})\\\ln(8000)=\ln(4000)+.07t\ln(e)\\\ln(8000)=\ln(4000)+.07t\\\frac{\ln(8000)}{\ln(4000)}=.07t\\\frac{\ln(8000)}{.07\ln(4000)}=t\\ 15.479=t
It will take 15.479 years

Answer:
the probability of having sickle cell anemia given that you are African-American is P( B|A) =0.288
Step-by-step explanation:
Using Bayes's theorem
P( B|A) = P( A∩B)/P(A)
where P( B|A) = probability of the event B knowing that A happened , P( A∩B) = probability that A and B happen (joint probability of A and B) , P(A) = probability of event A
if B= probability of having sickle cell anemia and A= probability of being African-American
then
P( A∩B) = 0.13
P(A) = 0.45
then
P( B|A) = P( A∩B)/P(A) = 0.13/0.45 = 0.288
P( B|A) =0.288
