Installation of some software package requires downloading 82 files. On average, it takes 15 seconds todownload one file, with a variance of 16 sec2. What is the (approximate) probability that the softwareis installed in less than than 20 minutes? (Use the Central Limit Theorem)

step-by-step explanation:

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)

no i do not : ( what is it?
