At American High School, there is a 25.5% probability a randomly selected student is an honor roll student, while there is a 37%
probability that a randomly selected student is a varsity athlete.
The probability that a student is an honor roll student and a
varsity athlete is 6%.

step-by-step explanation:

the original amount doesn't ''re just looking for the time it takes for 1/2 of the substance to we have

(1/2) =)     take the ln   of both sides

ln (1/2)   = )   and we can write

ln(1/2) = ) lne     and lne   = 1     so we have

ln(1/2) = -.1092t     divide both sides by -.1092

t = ln(1/2)/-.1092 = about 6.347 days = about 6.3 days (rounded)

i believe the correct answer is b.

mean, 40.6
