James, a buyer at EZ Tech, a Alaska-based purveyor of generators for people in remote areas, was doing some number crunching. EZ Tech was reevaluating its suppliers for a key component of the generator, the generator frame. After some extensive evaluation, James had narrowed it down to two suppliers and he would source from the one with the lowest total cost, everything else held equal. Given the following information, use total cost analysis to determine which supplier, is more cost-effective for EZ Tech. Late delivery of the generator frame results in either a lost sale (thus lost profit) or a customer backorder (each time there is a backorder, it costs $195). Assume for the cost comparison that order quantity is 2,800 units and that the annual requirement (forecast) is 74,000 units. For purposes of calculating quality problems, James uses the expected invoice amount as a base. What should James do? Enter as ###,###. Enter negative numbers as -###,###.

You have entered a model rocket contest with your friend, Tiffany. You have been working on a pressurized rocket filled with nitrous oxide. Tiffany has determined the minimum atmospheric pressure at which the rocket fuel is stable. Based not hat value, and the equations given below, your task is to determine the optimum launch angle and initial velocity to maximize flight time. The goal is to re-use your rocket capsule, so you really want to avoid a fuel explosion.

The atmospheric pressure varies with elevation according to the equation: P(h)= 14.7e−h/10. where p is the pressure in psi and h, is an elevation in miles above sea levels. The height (in feet) of a rocket launched at an angle α degrees with the horizontal and an initial velocity, vo in feet/second, t seconds after launch is given by the equation h(t)=-16t^2+vo*t*sin(α).

1) If Tiffany has determined that the minimum safe pressure is 11 pounds per square inch, at what altitude will the rocket explode? Report your result in feet. Round to the nearest foot.

2) If the angle of launch is33o, with an initial velocity of 1,648 what is the minimum atmospheric pressure exerted on the rocket during its flight? Report your answer to one decimal place. Under these conditions, will the rocket explode during its flight?

3) If the angle of launch is32o, with an initial velocity of 1,908 what is the minimum atmospheric pressure exerted on the rocket during its flight? Report your answer to one decimal place. Under these conditions, will the rocket explode during its flight?

4) Tiffany has revisited her calculation and has now concluded that the minimum safe pressure for the fuel is 9 psi. What is the maximum height your rocket can achieve without exploding in flight? Report your answer in feet to the nearest foot.

5) Tiffany has (once again) checked her calculations, and you have verified with her that the safe pressure for your fuel is 9 and the fuel capsule holds enough fuel to produce an initial velocity of 2,169 feet per second. What launch angle will you use so that your rocket achieves the maximum safe altitude? Round your answer to the nearest tenth of a degree.

42.A rail road is being proposed by the government to join two neighboring cities. The rail road will significantly reduce the travel time between the two cities. The only concern is that to set up the infrastructure for the rail road, approximately ten square miles of forests will need to be cleared. The forest is known for its flora and fauna and regularly attracts people from all over the country. Any construction activity in the forest would deprive future generations of this rich heritage. Thus the plan for the proposed rail road has been shelved because of the idea that the environment should be protected so that future generations may live in it, and have the choices as individuals have today. The above is an example of:

Select one:

a. social fairness.

b. an aesthetic argument.

c. an environmental impact statement.

d. incentives.

e. externalities.

43.Which of the following statements holds true for the concept of “fairness”?

Select one:

a. It refers to the duty to treat equals equally and unequals unequally.

b. It refers to the duty to compensate others when we harm them.

c. It refers to the duty to keep our promises and hold up our end of bargains.

d. It refers to the duty to thank and remember those who help us.

e. It refers to the idea that when you set up rules for resolving dilemmas, you don’t get to know beforehand which side of the rules you will fall on.

c. reporting.

d. a bribe.

e. whistleblowing.

45._____ refers to the argument that discrimination is wrong because it treats people unequally for reasons not involving merit.

Select one:

a. The fairness argument

Using the following case, describe how you would set up a program for young boy Jonathon who is watching too much T.V. and not getting his homework done, by using principles from operant conditioning (behavior modification). Be sure to include all of he tasks you would use before getting started. Determine the target behavior you would seek to change. include techniques that both increase and decrease the target behavior and those behaviors closely associated with the target behavior.

Jonathon is an eight-year-old boy. He is in the third grade and Bonneville Elementary School in Salt Lake County. He is the middle of three children. His older brother is age l l and his younger sister is age four. All three children live with their biological mother. Their parents divorced a year ago.

The children's father, Marquis, has a new partner and they live in an apartment approximately 15 miles from Jonathon, his mom, and his siblings. His mother is not seeing anyone at this time, so her evenings are spent at home with the children. She is, however, employed outside of the home and works as a clerk at a local convenience store.

Once a week, and every other weekend, the kids go to their father's house. Jonathon has begun complaining about being there as he reports it is not much fun because his father is "never there". He indicated that his dad's girlfriend isn't very friendly and that she orders Jonathon and siblings around all of the time.    

Jonathon did well is school, until his parents began to have relationship problems. His mom especially noticed a change in his grades after his father moved out of the house, just over a year ago. Prior to that, he was earning A and B grades and seemed to enjoy his teachers and classmates.

He has been assessed and does not have any neurological problems or learning disorders. As the school social worker, you have been asked to help Jonathon by setting up a behavioral program that will improve his grades.   Your assignment is to set up a program that addresses his study habits. He has been watching TV excessively, according to his mother, and he his neglecting to do his homework. As a result, he is getting D and F grades in his classes

The plant asset and accumulated depreciation accounts of Pell Corporation had the following balances at December 31, 2020:

Transactions during 2021 were as follows:

1. On January 2, 2021, equipment were purchased at a total invoice cost of $230,000, which included a $4,900 charge for freight. Installation costs of $21,000 were incurred.
2. On March 31, 2021, a small storage building was donated to the company. The person donating the building originally purchased it three years ago for $19,000. The fair value of the building on the day of the donation was $14,000.
3. On May 1, 2021, expenditures of $44,000 were made to repave parking lots at Pell's plant location. The work was necessitated by damage caused by severe winter weather. The repair doesn't provide future benefits beyond those originally anticipated.
4. On November 1, 2021, Pell acquired a tract of land with an existing building in exchange for 10,000 shares of Pell’s common stock that had a market price of $32 per share. Pell paid legal fees and title insurance totaling $20,000. Shortly after acquisition, the building was razed at a cost of $29,000 in anticipation of new building construction in 2022.
5. On December 31, 2021, Pell purchased a small storage building by giving $13,750 cash and an old automobile purchased for $15,000 in 2014. Depreciation on the old automobile recorded through December 31, 2021, totaled $11,250. The fair value of the old automobile was $3,450.

Required:

For each asset classification, prepare a schedule showing depreciation for the year ended December 31, 2021, using the following depreciation methods and useful lives:

Land improvements—Straight line; 15 years.
Building—150% declining balance; 20 years.
Equipment—Straight line; 10 years.
Automobiles—Units-of-production; $0.50 per mile

Depreciation is computed to the nearest month and no residual values are used. Automobiles were driven 35,000 miles in 2021. (Do not round intermediate calculations and round your final answers to 2 decimal places.)

You work for a small advertising agency in Greengrass, N.Y. The agency’s principal
advertising clients are automobile dealers and automobile repair shops. The agency has a good
record of placing advertisements for its clients in both real-space and on the internet.
Last week, you were considering buying a used car, and you found a web-site called
“CarValues.com.” The web site contains a database of information about used vehicles on the
market. The (searchable) database contains dealer-written factual descriptions of the make,
model, color and condition of the vehicle; the number of miles on the vehicle; how long the
vehicle has been on the market; and the price history of the vehicle (what it was originally
offered for, and any subsequent price reductions).
The web site was very helpful to you as a consumer. The data base also contained
information about past used-car sales in the area for the prior 6 months. The formatting on
CarValues.com was not good, and the interface was not user-friendly. You are confident the
developers who work for your company would have created a more user-friendly website.
When you got to work on Monday, a light bulb went on in your head. Why don’t we
create a car-selling website for our advertising clients? They would love it. All we need is a
database to start with. And one is available – right there on the internet, at CarValues.com. So,
you go back and check. There was no Terms of Use Agreement!!! Their data is right there for the
taking. Once we have the data, our company can update the information on our own going
forward without having to copy it from CarValues. But being able to use the CarValues
information would help us get started right away.
Your technician says he can capture all the existing data in minutes. Then your
organization can do the updating going forward as new cars come on the market and existing
ones are sold.
You mention your idea to, Carla Speil, the head of the agency at lunch. She is intrigued.
But is it legal? What are the potential consequences if CarValues.com finds out? ...She sees the
rewards.... But what are the risks? “Should we do it?,” she asks. Unusual for an advertising
executive, she seemed concerned about the ethics.
Write a one-page memo, Ms. Speil says, answering her questions.

Lon Timur is an accounting major at a midwestern state university located approximately 60 miles from a major city. Many of the students attending the university are from the metropolitan area and visit their homes regularly on the weekends. Lon, an entrepreneur at heart, realizes that few good commuting alternatives are available for students doing weekend travel. He believes that a weekend commuting service could be organized and run profitably from several suburban and downtown shopping mall locations. Lon has gathered the following investment information.

1. Mean entry-level salaries for college graduates with mechanical engineering degrees and electrical engineering degrees are believed to be approximately the same. A recruiting office thinks that the mean mechanical engineering salary is actually lower than the mean electrical engineering salary. The recruiting office randomly surveys 44 entry level mechanical engineers and 58 entry level electrical engineers. Their mean salaries were $46,300 and $46,900, respectively. Their standard deviations were $3420 and $4230, respectively. Conduct a hypothesis test at the 5% level to determine if you agree that the mean entry- level mechanical engineering salary is lower than the mean entry-level electrical engineering salary. Let the subscript m = mechanical and e = electrical.
NOTE: If you are using a Student's t-distribution for the problem, including for paired data, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)

Part (d)State the distribution to use for the test. (Enter your answer in the form z or t_df where df is the degrees of freedom. Round your answer to two decimal places.)

Part (f)What is the p-value? (Round your answer to four decimal places.)

2.Some manufacturers claim that non-hybrid sedan cars have a lower mean miles-per-gallon (mpg) than hybrid ones. Suppose that consumers test 21 hybrid sedans and get a mean of 31 mpg with a standard deviation of 7 mpg. Thirty-one non-hybrid sedans get a mean of 20 mpg with a standard deviation of three mpg. Suppose that the population standard deviations are known to be six and three, respectively. Conduct a hypothesis test at the 5% level to evaluate the manufacturers claim.

Part (d)State the distribution to use for the test. (Round your answers to two decimal places.)

Part (e)What is the test statistic? (If using the z distribution round your answer to two decimal places, and if using the t distribution round your answer to three decimal places.)

Part (f)What is the p-value? (Round your answer to four decimal places.)

NOTE: If you are using a Student's t-distribution for the problem, including for paired data, you may assume that the underlying population is normally distributed. (In general, you must first prove that assumption, though.)
