An equation was created for the line of best fit from actual enrollment data. It was used to predict the dance studio enrollment values shown in the table below: Enrollment Month January February March April May June Actual 500 400 550 550 750 400 Predicted 410 450 650 650 600 450 Residual 90 −50 −100 −100 150 −50 Analyze the data. Determine whether the equation that produced the predicted values represents a good line of best fit. No, the equation is not a good fit because the sum of the residuals is a large number. No, the equation is not a good fit because the residuals ar

    Analyze the data. Determine whether the equation that produced the predicted values represents a good line of best fit. No, the equation is not a good fit because the sum of the residuals is a large number. No, the equation is not a good fit because the residuals are all far from zero. Yes, the equation is a good fit because the residuals are not all far from zero. Yes, the equation is a good fit because the sum of the residuals is a small number.

    i don't know sorry. i guess i've done this in the past but i can't remember the sum of the residuals is - 60 which does not seem too bad but the residuals themselves are all far from zero. i would guess that b is the correct option.

    I agree I hate mac lol... I just asked because I don't really understand the graph and I don't see the equation for the line of best fit...

    That's weird....There should be an equation for the line of best fit...Or many that may be because quite a bit of the answer is missing lol

    it says that the equation was used to predict the dance studio enrollment values shown (the table i gave you) I hope that this helps lol? @undeadknight26

    I think it would be no it's not a good fit mostly because all the residual is far from 0...Or B.
