Long-Life Insurance has developed a linear model that it uses to determine the amount of term life Insurance a family of four should
have, based on the current age of the head of the household. The equation is:
y=150 -0.10x
where
y= Insurance needed ($000)
x = Current age of head of household
b. Use the equation to determine the amount of term life Insurance to recommend for a family of four of the head of the household is
40 years old. (Round your answer to 2 decimal places.)

Beeson Co. is experiencing a decrease in sales and operating income for the fiscal year ending December 31st. Julia Faure, controller of Beeson Co., has suggested that all orders received before the end of the fiscal year be shipped by midnight, December 31st even if shipping department must work overtime. Since Beeson Co. ships all merchandise FOB shipping point, it would record all such shipments as sales for the year ending December 31st, thereby offsetting some of the decreases in sales and operating income.Discuss whether Julia Faure is behaving in a professional manner and what are the implications of her actions?
Some citizens complained to city council members that there should be equal protection under the law against the occurrence of
crimes. The citizens argued that this equal protection should be interpreted as indicating that high-crime areas should have more
police protection than low-crime areas. Therefore, police patrols and other methods for preventing crime (such as street lighting or
cleaning up abandoned areas and buildings) should be used proportionately to crime occurrence.
The city has been broken down into 20 geographic areas, each containing 5,000 residences. The police recognize that not all crimes
and offenses are reported: people do not want to become involved, consider the offenses too small to report, are too embarrassed to
make a police report, or do not take the time, among other reasons. Every month, because of this, the police are contacting by phone
a random sample of 800 of the 5,000 residences for data on crime. (Respondents are guaranteed anonymity.) The 800…

- Seas Beginning sells clothing by mail order. An important question is when to strike a customer from the companys mailing list. At present, the company strikes a customer from its mailing list if a customer fails to order from six consecutive catalogs. The company wants to know whether striking a customer from its list after a customer fails to order from four consecutive catalogs results in a higher profit per customer. The following data are available: If a customer placed an order the last time she received a catalog, then there is a 20% chance she will order from the next catalog. If a customer last placed an order one catalog ago, there is a 16% chance she will order from the next catalog she receives. If a customer last placed an order two catalogs ago, there is a 12% chance she will order from the next catalog she receives. If a customer last placed an order three catalogs ago, there is an 8% chance she will order from the next catalog she receives. If a customer last placed an order four catalogs ago, there is a 4% chance she will order from the next catalog she receives. If a customer last placed an order five catalogs ago, there is a 2% chance she will order from the next catalog she receives. It costs 2 to send a catalog, and the average profit per order is 30. Assume a customer has just placed an order. To maximize expected profit per customer, would Seas Beginning make more money canceling such a customer after six nonorders or four nonorders?arrow_forwardDigital Controis, Inc. (DCI), manufactures two models of a radar gun used by police to monitor the speed of automobiles. Model A has an accuracy of plus or minus 1 mile per hour, whereas the smaller model B has an accuracy of plus or minus 3 miles per hour. For the next week, the company has orders for 100 units of model A and 150 units of model B. Although DCI purchases all the electronic components used in both models, the plastic cases for both models are manufactured at a DCI plant in Newark, New Jersey. Each model A case requires 4 minutes of injection-molding time and 6 minutes of assembly time. Each model B case requires 3 minutes of injection-molding time and 8 minutes of assembly time. For next week, the Newark plant has 600 minutes of injection-molding time avallable and 1,080 minutes of assembly time availab The manufacturing cost is $10 per case for model A and $6 per case for model B.

- There are two companies manufacturing drones. Company A manufactures mass market drones, while company B manufactures customised drones according to customers’ requirements. In 2020, company A produces 3,200 drones, 3% of which were found to be defective and cannot pass the quality check. Company A employs 5 workers working an average of 8 hours a day in the drone production, and they worked 200 working days in 2020.In contrast, company B produces 900 drones, 10% of which were found to be defective and cannot pass the quality check. Company B employs 3 workers working an average of 6 hours a day in the drone production, and they worked 170 days in 2020.

The collection point for both fuel companies is located at the same seaport. The general manager of Mansfield Energy Corp intends to hire a consultant to train Mansfield Energy Corp’s employees regarding the new procedures for affixing the fuel lines at the collection point to the high-capacity storage tanks and is debating whether the competitor should be invited to attend given that they use the same seaport. The general manager is mindful of the high cost of hiring the consultant and sourcing the equipment to train Mansfield Energy Corp’s employees and is therefore hesitant to invite his competitors. The manager is also aware that there have been no accidents at the port since operations started 10 years ago and might not invite the competitors to participate in the training.

- Author: Leo A. Ruggle, Professor, Department of Accounting, Mankato State University Arnie Armstrong has been with Pierce Auto Parts Manufacturing Company for 23 years. Recently, he was appointed Director of Manufacturing Computer Services. In just six weeks in this new position, [he] has moved to reduce the amount of information provided to manufacturing department managers by 60 percent. He argues that excess data is distracting, unused, and expensive to provide. Willy McClean has been department manager for 12 years. During a coffee break with some of his department production supervisors, Willy is quite vocal about the change. “Who’s this guy Armstrong to tell us what data we need? He needs to be out here for a few weeks to find out what it’s like. Keep it quiet, but I’ve got a contact in Computer Services who’ll get me all the data analyses I want for just a $20 bill each month. It’s a good deal, and Armstrong will never know.

The company recently developed an inventory control system for a national clothing manufacturer. The system gathers sales information on an hourly basis from clothing retailers nationwide. This information is then used by all departments (including the accounting, shipping, and ordering departments) to control the functions of the clothing manufacturer. Emily suspects that the inventory functions of the system are not sufficiently tested, although they have passed all their contracted (legal) tests. However, she is pressured by her employers to sign off on the software. Whilst she is only required to perform tests which have been agreed to in the original contract, her considerable experience in software testing has led her to be concerned over the quality of the system. Her employers say that they will go out of business if they do not deliver the software on time. Emily knows that if any section of…arrow_forward
