Asked by mary

the average annual rainfall for a town is 43.2 inches. I know the monthly rainfall has to be 3.6 inches. the difference of a given month's rainfall from the average monthly rainfall is called the deviation. what is the deviation for each month shown? may 2 3/5 inches, june 7/8 inches, and july 4 1/4 inches. I'm not sure but I subtracted each month from the monthly rainfall. is that correct. then another part to this question is: the average monthly rainfall for the previous 9 months was 4 inches. did the town exceed its average annual rainfall, if so by how much? I'm don't know how to figure this question out

everything appears ok down to the last part.

4"/mo for 9 months is 36". Since the average annual amount is 43.2", those 9 months did not exceed the annual average.

This is to be expected, since the monthly amount was only a little bit more than the usual monthly average.
