Directions:
Answer the following questions.
1. What type of relationship is displayed on the scatter plot? Based on that relationship, would you expect the fuel efficiency to increase or decrease as displacement increases. | |
2. You interested in purchasing a vehicle with a displacement of 289 cubic inches (CID). What is the car’s expected fuel efficiency. | |
3. You must decide whether to keep your vehicle or trade it in for the one with a displacement of 289 CID. Fuel cost is rising. You are on a budget. After all of your bills are paid, you have purchased food and taken care of your necessities, you save $20 a month. Your note will remain the same. Your current vehicle has a fuel efficiency of 22 miles per gallon (mpg). Would you trade in your vehicle for the one above or keep your vehicle? Why or why not? |
