Provide an appropriate response.Does it appear that a linear model or a power model is the best fit for the data given in the table below? Explain your choice.

What will be an ideal response?


Since the first differences are closer to being equal than the second differences, a linear model will be a better fit than a power model.

An engine on a test stand was operated at two fixed settings, each with an appropriate load. At the first setting, fuel consumption was 1 gal every 15 min. At the second setting, it was 1 gal every 20 min. The test took 10 h, and 37 gal of fuel were used. How long did the engine run at each setting? 

A. The engine ran for 7 h at the first setting, The engine ran for 3 h at the second setting.   B. The engine ran for 3 h at the first setting, The engine ran for 7 h at the second setting.   C. The engine ran for 7.5 h at the first setting, The engine ran for 2.5 h at the second setting.   D. The engine ran for 4 h at the first setting, The engine ran for 6 h at the second setting.   E. The engine ran for 6 h at the first setting, The engine ran for 4 h at the second setting.
