Chapter 8, Problem 9SE
Refer to Exercise 2 in Section 8.2.
- a. Using each of the three models in turn, predict the NOx emission when Speed = 1500, Torque = 400, and HP = 150.
- b. Using each of the three models in turn, predict the NOx emission when Speed = 1600, Torque = 300, and HP = 100.
- c. Using each of the three models in turn, predict the NOx emission when Speed = 1400, Torque = 200, and HP = 75.
- d. Which model or models appear to be the best? Choose one of the answers, and explain.
- i. The model with Speed and Torque as independent variables is the best.
- ii. The model with Speed and HP as independent variables is the best.
- iii. The model with Speed, Torque, and HP as independent variables is the best.
- iv. The model with Speed and Torque and the model with Speed and HP are about equally good: both are better than the model with Speed, Torque, and HP.
- v. The model with Speed and Torque and the model with Speed, Torque, and HP are about equally good; both are better than the model with Speed and HP.
- vi. The model with Speed and HP and the model with Speed, Torque, and HP are about equally good; both are better than the model with Speed and Torque.
- vii. All three models are about equally good.

Your personal trainer suggests that you supplement with at least 10 grams of creatine, 39 grams of L-glutamine, and 90 grams of BCAAs each week. You are thinking of combining Xtend and Gainz to provide you with the required nutrients. How many servings of each should you combine to obtain a week's supply that meets your trainer's specifications at the least cost? (If an answer does not exist, enter DNE.)
