Question

This year has had a significant amount of rainfall, but not as much as last year, which had 31 inches and is measured from July 1 to June 30.

If it has already rained 26 inches this year (February 28th), what is the average monthly rainfall that will have to occur for the rest of the season in order to equal last year?

Round to the nearest hundredth.

Answer 1

Using the mean concept, it is found that the average monthly rainfall that will have to occur for the rest of the season in order to equal last year is of 1.25 inches per month.

What is the mean?

The mean of a data-set is given by the sum of all observations in the data-set divided by the number of observations.

In the four months from March 1 to June 30, 31 - 26 = 5 inches are needed to match last year's amount, hence the average is given by:

A = 5/4 = 1.25 inches per month.
