Problem 2.7.31

Automotive Engineering The fuel efficiency, in miles per gallon, for a certain midsize car at various speeds, in miles per hour, is given in the table below. Fuel Efficiency of a Midsize Car mph mpg25 2930 3235 3340 3545 3450 33a. Find a quadratic model for these data. b. Use the model to predict the fuel efficiency of this car when it is traveling at a speed of 50 mph. Round to the nearest tenth miles per gallon.

Step-by-Step Solution:
Step 1 of 3

.Let's begin with the first question. What was the prediction given in the article in 1990 The wording in the book is somewhat vague. Specifically, the question is asking what the quadratic model predicted for the year 2035. So, since t=0 represents 1960, and we want to represent 2035, we will take the difference. That gives us: .Now we will look at the second question. Does this prediction for the year 2035 seem accurate The question is asking how the prediction given by the quadratic model (which uses data from 1960‐1990) compares with the prediction given by the linear model (which uses data from 1980‐2010) .Therefore, the prediction given by quadratic model is too high (when compared to the linear model). These models were developed using a procedure cal
