There are 5 people sitting at a table and they have no known ages, what we do know is that they have a mean of 22 in age

it is also known that the mean is bigger then the median,

what could each of there ages be?

2 2/3 hours duhh silly

step-by-step explanation:

5/20 so 25%

step-by-step explanation:

ending amount = beginning amount / (2^n)

where "n" = number of half-lives (or elapsed time / half-life)

ending amount = 50 mg / (2 ^10 / 5.3)

ending amount = 50 mg / (2 ^ 1.8867924528)

ending amount = 50 m / 3.6981210597

ending amount = 13.5203794557 mg

or about 13.5 mg remain
