Help solve Otitis media, or middle ear infection, is initially treated with an antibiotic.Researchers have compared two antibiotics, A and B, for their costeffectiveness. A is inexpensive, safe, and effective. B is also safe. However,it is considerably more expensive and it is generally more effective. Use thetree diagram to the right (where the costs are estimated as the total costof medication, office visit, ear check, and hours of lost work) to answer thefollowing.a. Find the expected cost of using each antibiotic to treat a middle earinfection.b. To minimize the total expected cost, which antibiotic should be chosen?a. The expected cost of using antibiotic A is $(Round to the nearest cent as needed.)The expected cost of using antibiotic B is $(Round to the nearest cent as needed.)b. To minimize the total expected cost, which antibiotic should be chosen?0.60 Cure $59.30A0.40 No cure $96.150.85, Cure $69.15B0.15No cure $106.00A. Antibiotic B minimizes the total expected cost. Therefore, antibiotic B should be chosen.B. Antibiotic A minimizes the total expected cost. Therefore, antibiotic A should be chosen.

If you are performing a break-even analysis for a business and their cost and revenue equations are dependent, explain what this means for the company's profit margins.
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.

You manage a systems engineering firm, and you often get projects by bidding on them. Animportant aspect of bidding on such projects is estimating the amount to bid: a bid that’s toohigh may mean your firm isn’t awarded the project, but a bid that’s too low may mean you areawarded the project and lose money in the process. You have two cost engineers that estimateproject costs. Engineer 1 estimates about 70% of bids while Engineer 2 estimates the rest. It isknown that the error rate for Engineer 1 is such that 0.02 is the probability of an error occurswhen she does the cost estimation, whereas the probability of an error in the estimate ofEngineer 2 is 0.04. Suppose a bid arrives and a serious error occurs in estimating cost. Whichengineer would you guess did the work?

Accounting procedures allow a business to evaluate their inventory costs based on two methods: LIFO (last in first out) or FIFO (first in first out). A manufacturer evaluated its finished goods inventory (in $000s) for five products with the LIFO and FIFO methods. To analyze the difference, they computed FIFO − LIFO for each product. We would like to determine if the LIFO method results in a lower cost of inventory than the FIFO method.
