17. A home theater in a box is the easiest and cheapest way to provide surround sound for ahome entertainment center. A sample of prices is shown here (Consumer Reports BuyingGuide, 2004). The prices are for models with a DVD player and for models without aDVD player.Models with DVD PlayerPriceModels without DVD PlayerPrice$450300400500400Pioneer HTP-230Sony HT-DDW750Kenwood HTB-306RCA RT-2600Kenwood HTB-206$300300360290300Sony HT-1800DPPioneer HTD-330DVSony HT-C80ODPPanasonic SC-HT900Panasonie SC-MTICompute the mean price for models with a DVD player and the mean price for mod-els without a DVD player.

Cholesterol Cholesterol in human blood is necessary, but too much can lead to health problems. 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.
