Textbook Question
Chapter 3.1, Problem 45E
Protein Supplements Exercises 45-48 are based on the following data on three popular protein supplements. (Figures shown correspond to a single serving)5
Protein (g) | Carbohydrates (g) | Sodium (mg) | Cost ($) | |
Designer Whey (Next) | 18 | 2 | 80 | 0.50 |
Muscle Milk (Cytosport) | 32 | 16 | 240 | 1.60 |
Pure Whey Protein Stack (Champion) | 24 | 3 | 100 | 0.60 |
You are thinking of combining Designer Whey and Muscle Milk to obtain a 7-day supply that provides exactly 280 grams of protein and 56 grams of carbohydrates. How many servings of each supplement should you combine in order to meet your requirements? What will it cost?

a) Explain why you cannot use that model to estimate the fat content of a burger with 600 calories.
Choose the correct answer below.
A. The regression model was for predicting calories from fat, not the other way around.
B. The regression model cannot extrapolate to the prediction value.
C. The regression model was for predicting fat from calories, not the other way around.
b) Using an appropriate model, estimate the fat content of a burger with 600 calories.

There are three main types of cholesterol: HDL (high-density lipoproteins), LDL (low-density lipoproteins), and VLDL (very low-density lipoproteins). HDL is considered “good” cholesterol; LDL and VLDL are considered “bad” cholesterol. A standard fasting cholesterol blood test measures total cholesterol, HDL cholesterol, and triglycerides. These numbers are used to estimate LDL and VLDL, which are difficult to measure directly. Your doctor recommends that your combined LDL/VLDL cholesterol level be less than 130 milligrams per deciliter, your HDL cholesterol level be at least 60 milligrams per deciliter, and your total cholesterol level be no more than 200 milligrams per deciliter. (a) Write a system of linear inequalities for the recommended cholesterol levels. Let x represent the HDL cholesterol level, and let y represent the combined LDL VLDL cholesterol level. (b) Graph the system of inequalities from part (a). Label any vertices of the solution region. (c) Is the following set of cholesterol levels within the recommendations? Explain. LDL/VLDL: 120 milligrams per deciliter HDL: 90 milligrams per deciliter Total: 210 milligrams per deciliter (d) Give an example of cholesterol levels in which the LDL/VLDL cholesterol level is too high but the HDL cholesterol level is acceptable. (e) Another recommendation is that the ratio of total cholesterol to HDL cholesterol be less than 4 (that is, less than 4 to 1). Identify a point in the solution region from part (b) that meets this recommendation, and explain why it meets the recommendation.arrow_forwardGrade Point Average In many universities students are given grade points for each credit unit according to the following scale: A 4 points B 3 points C 2 points D 1 point F 0 point For example, a grade of A in a 3-unit course earns 43=12 grade points and a grade of B in a 5-unit course earns 35=15 grade points.
