An equation was used to predict the number of possible enrollments in an afterschool program for the first 6 months of the year. The actual enrollments are also listed.

Actual enrollment 55 80 95 100 115 90
Predicted enrollment 75 80 85 90 95 100

The sum of the residuals is

Addition is an important concept of Mathematics. When we add two or more numbers, the result or the answer we get can be defined as the SUM.

Here, we know that;

Residual value = Actual result - Predicted result,

Actual enrollments are 55, 80, 95, 100, 115 and 90,

While, predicted enrollments are 75, 80, 85, 90 and 95,

Now,

the sum of the residuals = the sum of actual enrollments - the sum of predicted enrollments

= (55+80+95+100+115+90) - (75+80+85+90+95+100)

= 535 - 525

= 10

Thus, The sum of the residuals is 10.
