A copy machine makes 36 copies in a minute (1).
Multiply 36 copies by 3.75 (3 min and 45 sec) to find how many copies it can make within that time.
(36)(3.75) = 135
The copy machine can make 135 copies in 3 minutes and 45 seconds.
For calculating the mean, you want to add up all of the numbers then divide by how many numbers there are. So you'd do:
5+10+12+4+6+11+13+5 then divide that by 8
The answer to your question is: 8.25
