create a diagram of the situation 81% of college students take online classes, 36% online students have gained more than 5 pounds in last 6 months 15% students did not take online gained 5 pounds in the last 6 months.
College students are graduating with the highest debt burden in history. The bar graph shows the mean, or average, student-loan debt in the United States for five selected graduating years from 2001 through 2013.
Here are two mathematical models for the data shown by the graph. In each formula, D represents mean student-loan debt, in dollars, x years after 2000. The Model 1 is, D = 1188x + 16,218 and the Model 2 is D = 46x2 + 541x + 17,650.
Solve, a. Which model better describes the data for 2001?b. Does the polynomial model of degree 2 underestimate or overestimate the mean student-loan debt for 2013? By how much?
A researcher surveyed 80 patients at a certain hospital. The histogram below gives the length of
time patients waited to see a doctor at the hospital. The classes, in minutes, are 0 - 1.9, 2 - 3.9,
etc., and the vertical axis represents the number of patients.

- 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.arrow_forwardSuppose a basketball player has made 70% of their foul shots this season.
