Nine owners of Honda Civics in Richmond want to know if they get different gas mileage with their cars than what the Honda Corporation reports. Honda of America states that all Honda Civics sold in America get an average of 33 MPG (miles per gallon). The nine Honda owners drive their cars and record the MPG listed below. Use a single-sample t-test to determine the outcome (alpha = .05, two-tailed).

Owner 1: 29 MPG
Owner 2: 32 MPG
Owner 3: 31 MPG
Owner 4: 30 MPG
Owner 5: 30 MPG
Owner 6: 29 MPG
Owner 7: 28 MPG
Owner 8: 31 MPG
Owner 9: 30 MPG
M = 30

Dillard Company starts the year with $10,000 in its cash account, $10,000 in its equipment account, $2,000 in accumulated depreciation and $18,000 in its retained earnings account. During the year Dillard sells the equipment for $8,570. After the sale of equipment is recorded, the retained earnings account will have a balance of $________.

18000-1430 (which was from 10000 of equip minus 8570)-2000 is 14570 = wrong

=======================================

Uber Inc purchased a car for $43,100. The car has a salvage value of $2,800 and is estimated to be in use for 150,000 miles. What is the accumulated depreciation at the end of Year 2 assuming mileage used in year 1 was 13,310, year 2 was 16,670, and year 3 was 18,040? $_______

43100-2800/150000=0.26866666, 13310*0.269 is 3576 and 16670*0.269 is 4479 then add 3576+4479 for final answer of 8055 = wrong

===========================================

On January 1, Year 1, Randall Moving Company paid $27,600 cash to purchase a truck. The truck was expected to have a five year useful life and an $4,900 salvage value. If Randall uses the straight-line method, thebook value at the end of Year 2 is $______

27600-4900 / 5 * 3 = 9080 then 27600-9080 is final answer of 18520 = wrong

Using a Java.

2. Write a Java program calculate_fare.java to take the input for number of miles, and the class of journey (1,2, or 3, for first, second, and third class respectively), for a train journey.

The program should then calculate and display the fare of journey based on the following criteria:
Note: Use Switch...case and if...else construct

Rubric:
- Input, usage of appropriate data types - 2 points
- Appropriate usage of if...else in each case of switch construct for each class of journey : 4 points
- Documentation and appropriate variable names- 2 points

The layout of  switch case should be as follows:

switch(cls)//class

{

     case 1: if construct for calculating fare for class 1

     case 2: if construct for calculating fare for class 2

     case 3: if construct for calculating fare for class 3

     default: Display it is an invalid class

Land footprint of solar energy:

(a) In 2016, Arizona’s total annual electricity consumption was 78.05 million MWh. What is this in terms of kWh per day?

(b) Land footprint: The average daily insolation in Phoenix is 5.38 kWh/m2/day. Given this daily energy input, how much land area would you need (in square miles) to generate all of Arizona’s daily electricity from the following types of PV panels:

i. Mono-crystalline Si panels with an efficiency of 22 %?

ii. Thin film CdTe with an efficiency of 12%?

(c) Translate to rooftops: Assuming we use 22% efficient mono-crystalline Si panels, how many rooftops would that take if we put the panels on:

i. Wal-Mart stores with an average size of 102,000 square feet?

ii. Household rooftops with an average size of 2,000 square feet?

(d) Reflection: These types of crude statistics get used all the time in public debates about solar energy. Do you think they’re useful? Why or why not? Take about 3-4 sentences to explain what we learn from this exercise and whether you think it’s useful for talking about solar energy.

For a summer job you take a position as an accident investigator for your local police force. On your first day you are called to the scene of a possibly minor accident at a large intersection with a 4-way stop. From the positions of the cars you can see that driver A was traveling northward in a small car and driver B was traveling eastward in a car that looks like it has approximately twice the mass of car A. The debris from their collision is in the center of the intersection. You can see the 5 m long marks left by the skidding tires that lead from the impact point to where the cars now rest, stuck together. The skid marks point in a direction 18.4˚east of north. From your measurements of the marks and from knowing something about the frictional force of asphalt on tires, you estimate that the cars were moving about 20 miles per hour immediately after the collision. Driver A says that driver B ran through a stop sign. Driver B says the opposite. You determine the speeds that each driver was traveling to help determine who is at fault. Make sure that y explain clearly how you determined the speeds of each car.

Felix Baumgartner, an Austrian skydiver and daredevil, made history’s highest and fastest jump. After ascending to more than 128,000 feet in capsule tethered to a helium balloon, Baumgartner jumped and became the first human to break the sound barrier as he fell at a rate of 833 miles per hour and had a free-fall of more than 4 minutes.

The event was sponsored and funded by Red Bull – a company known for pushing the envelope of crazy and risky sports.The company doesn’t consider this a stunt though, preferring to characterize the program as a professional flight test program. Red Bull spent more than five years on the project with an expert staff of scientists, engineers, and physicians – many of whom had experience with NASA programs. The cost to Red Bull has not been disclosed, but estimates on the return to the company in regards to visibility, branding, and goodwill tops $8 billion.

Why do companies sponsor events – oftentimes events that seem to have little to do with their products?

What do companies gain? What do they risk?

How does the Stratos project fit with the Red Bull brand and target market? How does it fit with other promotional tools used by Red Bull?

1. Blue Spruce Corp. purchased a new machine on October 1, 2019, at a cost of $134,000. The company estimated that the machine will have a salvage value of $20,000. The machine is expected to be used for 10,000 working hours during its 5-year life.

2. Yello Bus Lines uses the units-of-activity method in depreciating its buses. One bus was purchased on January 1, 2019, at a cost of $227,125. Over its 4-year useful life, the bus is expected to be driven 132,500 miles. Salvage value is expected to be $8,500.

Compute the depreciable cost per unit. (Round answer to 2 decimal places, e.g. 0.50.)

3. In recent years, Sheffield Transportation purchased three used buses. Because of frequent turnover in the accounting department, a different accountant selected the depreciation method for each bus, and various methods were selected. Information concerning the buses is shown as follows.

For the declining-balance method, the company uses the double-declining rate. For the units-of-activity method, total miles are expected to be 124,000. Actual miles of use in the first 3 years were 2018, 26,000; 2019, 31,500; and 2020, 29,500.

For Bus #3, calculate depreciation expense per mile under units-of-activity method. (Round answer to 2 decimal places, e.g. 0.50.)

5. At December 31, 2019, Sheffield Corp. reported the following as plant assets.

During 2020, the following selected cash transactions occurred.

Journalize the above transactions. The company uses straight-line depreciation for buildings and equipment. The buildings are estimated to have a 50-year life and no salvage value. The equipment is estimated to have a 10-year useful life and no salvage value. Update depreciation on assets disposed of at the time of sale or retirement. (Credit account titles are automatically indented when amount is entered. Do not indent manually. Record journal entries in the order presented in the problem.

HW Problem 5: A 150 kW motor drives a hollow round shaft at 1,200 rpm. The outer diameter of the shaft is 100-mm and the inner diameter is 0.95*outer diameter. It is made of AISI 1050 WQ&T at 425- deg C.

(a) Look online or the book and explain briefly what “WQ&T” in the material designation stand for, and how it is different than OQ&T. Which is stronger at the specified temperature?

(b) Determine the maximum torsional shear stress (Tau max) in the hollow shaft. Write the units. Hint: Use the kW power equation, find torque, and find J to find Tau max. Use N, mm, MPa.

(c) Determine the safety or no safety factor for static loading (ns) according to (i) Tresca theory, and (ii) von-Mises theory. Hint: Read Sy from table and then calculate Ssy by Tresca and von-Mises. Then use (ns,Tresca) = (Ssy,Tresca) / (Tau max); (ns,von) = (Ssy,von) / (Taumax).

(d) If the calculated safety factor is more than 4.0, what parameters would you change to bring it down below 4.0 (and of course, above 1.0)?
