I NEED HELP FAST The number of milligrams of an antibiotic in a person’s bloodstream, A(h), is dependent on the number of hours elapsed since taking the antibiotic, h. George took a 50-milligram dose of the antibiotic. One hour after taking the medicine, he had 25 milligrams of the antibiotic in his bloodstream. Two hours after taking the medicine, he had 12.5 milligrams of the antibiotic in his bloodstream. Which function can be used to find the number of milligrams of antibiotic in George's bloodstream after h hours?

A. A(h) = 25(0.5)h

B. A(h) = 0.5h + 50

C. A(h) = 50(0.5)h

D. A(h) = 50h2 + 25h + 12.5

hi! i think the answer is 1/2 : )

i think it might be a but you might want a second opinion

85.560%

step-by-step explanation:

conditional probability is defined as:

p(a|b) = p(a∩b) / p(b)

in other words, the probability that a occurs, given that b has occurred = the probability that both a and b occur / the probability that b occurs.

in this example:

p(turns 64 | turns 44) = p(turns 64 & turns 44) / p(turns 44).

if someone turns 64, they must have already turned 44, so:

p(turns 64 | turns 44) = p(turns 64) / p(turns 44)

on page 42, we see that of the original 100,000, 94944 turn 44, and 81234 turn 64.   therefore:

p(turns 64 | turns 44) = 81234 / 94944

p(turns 64 | turns 44) = 0.85560

table a is wierd
