6. Your client wants to determine the relationship between its annual Repairs \& Maintenance (R\&M) costs and a potential cost driver (number of machine hours worked). The output of a regression analysis showed the following information: Y-Intercept=126,078XVariable=122.12R-square=0.7852 Should your client use the equation (Y=$126,078+$122.12X) to predict next year's R \& M costs? A. Yes, because R-square is so high. B. No because R-square is so low. C. , because regression analysis cannot be relied upon. D. There is not enough information to make this prediction. 7. On a PV graph, break-even is located at what point? a. Where the profit line crosses the Y-axis. b. Where the profit line crosses the X-axis. c. Where the profit line intersects the total sales line d. Where the profit line intersects the total cost line
