You’re a logistics engineer for a manufacturer of hard seltzer. You use three different shipping companies (?1, ?2, ?3) to distribute seltzers. You contract with ?1 50% of the time, ?2 40% of the time, and ?3 10% of the time. Of those sent by ?1, 2% arrive after the guaranteed delivery time (late delivery). Similarly, 1% of those handled by ?2 arrive late, and 5% of shipments by ?3 arrive late. a. What is the probability that a randomly selected shipment arrived late? b. What is the probability that a randomly selected shipment was sent via ?1 and was late? c. If a randomly selected shipment arrived on time, what is the probability that it was not sent via ?1?

A $150 eReader comes with a warranty from an electronics business that covers theft (T) and accidental damage (AD) . Due to the high expense of repairing an eReader, it is more cost-effective for the business to provide the customer a complete refund to go toward another one. There is a 5.1% possibility that an AD (Accidenal Claim) claim will be made in any given year. Assume there can only be one claim made (not one of each type).Customers who report an eReader as stolen will get a reimbursement for 80% of the item's full price. A Theft (T) claim is likely to be submitted 3.5% of the time in any given year.What is the anticipated financial benefit or loss for the firm on each contract if the warrantee costs $15.95 for a year?(NOTE: Keep in mind that regardless of whether a claim is made, the consumer will pay for the warranty upfront.)
2. Many municipalities offer a variety of fare options for public transportation. This allows high use travelers a choice to pay a lower fare as a benefit of being a high user. The Transit Co. of Blue City, TX has three separate monthly bus fare options to choose from. The first is a standard “per ride" fare of $1.25 per ride. The second allows the rider to purchase a discount card. The cardholder pays $21 at the start of the month plus a fee of S0.50 per ride. Option 3 is a flat fee option where the rider pays $40 for thee month and may ride any bus at no additional cost during the month. Define the variable x to be the number of rides you take each month. Express each option as a function of x. Graph all three functions on the same set of axes. What is the break even number of rides between the options? If you only take 10 rides a month what option should you choose? If you take 40 rides a month what option should you choose? Watch the video posted in the Capstone #1 area involving…

Suppose a certain manufacturing company produces connecting rods for 4- and 6-cylinder automobile engines using the same production line. The cost required to set up the production line to produce the 4-cylinder connecting rods is $2,400, and the cost required to set up the production line for the 6-cylinder connecting rods is $3,600. Manufacturing costs are $14 for each 4-cylinder connecting rod and $19 for each 6-cylinder connecting rod. Hawkins makes a decision at the end of each week as to which product will be manufactured the following week. If a production changeover is necessary from one week to the next, the weekend is used to reconfigure the production line. Once the line has been set up, the weekly production capacities are 5,000 6-cylinder connecting rods and 7,000 4-cylinder connecting rods. Let 56 = 1 if the production line is set up to produce the 6-cylinder connecting rods; 0 if otherwise (a) Using the decision variables x4 and s, write a constraint that limits next…
There are several risks and costs associated with the airline's decision to overbook flights. If too many passengers show up, the airline may need to offer incentives for customers to give up their seats, which can be costly. If too few passengers show up, the airline may be forced to fly with empty seats, resulting in lost revenue. Furthermore, overbooking can lead to negative publicity and damage to the airline's reputation if too many customers are bumped from their flights. In terms of strategy, the airline must weigh the potential benefits of overbooking (maximizing revenue by filling as many seats as possible) against the potential risks and costs. The airline may also consider adjusting its overbooking policy based on factors such as the route, time of day, and historical data on no-show rates for specific flights. Overall, effective demand forecasting and capacity planning are crucial for the airline to optimize its operations and profitability while minimizing negative…

Oxford University in England is one of the oldest and most prestigious universities in the world. In 1902, a trust was set up to provide academic awards to American college graduates so they could attend Oxford. The Rhodes Scholarship was named after the primary benefactor of the award, Cecil Rhodes, a British philanthropist who wished to bring students from throughout the world to study at Oxford. Along with an endowment from Rhodes's will, the scholarship continues to be funded by generous benefactors including Canadian businessman John MacBain, who donated almost $120 million dollars to expand the program. The first class of American Rhodes Scholars entered Oxford in 1904. Applying for the Rhodes Scholarship is a rigorous process. Students who wish to apply must first be endorsed by their university. In 2014, 1600 students asked for endorsement but only 877 received it. The strongest applicants are then invited to appear for an interview. Rhodes Scholars are selected based on…

Two students in a microeconomics class traveled to a football game just before the midterm and drank too much to be able to study. So they telephoned their professor and lied to him, saying that a flat tire had delayed them. "No problem," said the professor. "Take the test tomorrow." When they arrived, the professor put each student in a separate room for taking the test. The first question, worth 5 points, was easy. The second question was worth 95 points: "Which tire?" Calculate, for each student, the expected test score.
