An equation was created for the line of best fit from the 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
acutal 120 140 150 140 150 130
predicted 80 150 110 150 110 150
residual 40 β10 40 β10 40 β20
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 residuals are all far from zero.
no, the equation is not a good fit because the sum of the residuals is a large number.
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.

Harold wrote this equation to model the level of water in a pool over time. the variable x represents time in hours. f(x) = 3,500 - 225x which statements about the situation are true? check all that apply. the water level is rising. the water level is falling. the initial level of water in the pool was 3,500 units. the initial level of water in the pool was 225 units. the pool was empty after 14 hours. the water was 2,600 units high after 4 hours.
