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.

Are cigarettes bad for people? Cigarette smoking involves tar, carbon monoxide, and nicotine (measured in milligrams). The first two are definitely not good for a person's health, and the last ingredient can cause addiction.

Suppose you took a survey designed to assess criminal justice students and their attitudes towards ending cash bail in California. You ask 100 students (randomly sampled) how much they'd be willing to pay to fund community supervision programs over the current cash bail system. There is another question that asks students if they believe reforming cash bail is a serious issue. Select all correct answers. The response variable is a student's belief that cash bail needs to be reformed. The reponse variable is the amount of tax a student is willing to pay to cover community supervision costs. Students answer yes or no to the question of whether they believe cash bail reform should occur. This means the samples are independent. Students answer yes or no to the question of whether they believe cash bail reform should occur. This means the samples are dependent.

Multiple choice Mid-West Publishing Company publishes college textbooks. The company operates an 800-telephone number whereby potential adopters can ask questions about forthcoming texts, request examination copies of texts, and place orders. Currently, two extension lines are used, with two representatives handling the telephone inquiries. Calls occurring when both extension lines are being used receive a busy signal; no waiting is allowed. Each representative can accommodate an average of 12 calls per hour. The arrival rate is 20 calls per hour. What percentage of calls receive a busy signal for the current telephone system with two extension lines? 34% 65% 16% 84% What percentage of calls are handled by the representative if the company has a telephone system with three extension lines? 34% 65% 16% 84% What is the average number of extension lines that will be busy if the company wants to handle 90% of the calls immediately? 2.5128 1.5626 3.1312 2.7126 What percentage of calls…
