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 ______. Numerical Answers Expected!

Respuesta :

I believe the answer is 10

Answer:

The sum of the residuals is 10.

Step-by-step explanation:

Since,

Residual value = Actual result - Predicted result,

Here,

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

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

Hence, 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
