Answer:

Poisson, as we have the mean number and not a proportion.

Step-by-step explanation:

Answer:

About 11.299 hours.

Step-by-step explanation:

To solve this problem, you can set up an equation to model the decay of the medicine. Let's call the time that medicine has been in the body x.

(1-0.0595)^x=0.5

0.9405^x=0.5

Taking the log x of both sides, you get

x=\log_{0.9405} 0.5

x\approx 11.299 hours. Hope this helps!
