An оperаtiоns mаnаger fits a multiple linear regressiоn model to predict the annual maintenance cost of heavy machinery (Y, measured in dollars) using three independent variables: equipment age in months (X1), average weekly operating hours (X2), and the preventive maintenance rating score on a 1–10 scale (X3).
