1) describe how the line of best fit and the correlation coefficient can be used to determine the correlation between the two variables in this graph. 2) calculate the residuals for this scatterplot.

Step-by-step explanation:

The closer the line of best fit is to the points the more accurate it is.  The correlation coefficient gives a numerical rank, where 1 is a perfect fit and the closer to 0 it is the less accurate it is.

I need the values of the line at the same x values as the scatterplot points.  After you have that take the difference of the value of the line of best fit and the corresponding scatterpoint.  if the point is higher than the line then the resiual will be negative and if the point is lower the residual will be positive.  Do you have the equation of the line of best fit?

we'll this would mean that the dunk tank and the bounce house are the same for 20 hours because the 2 represents that the two activities, and the 20 represents the amount of hours they both are. so with this said, it means that the answer is c. the costs for a dunk tank and bounce house are the same for 20 hours.

c.the costs for a dunk tank and bounce house are the same for 20 hours.

hope this .
