The accompanying table shows a portion of a data set that refers to the property taxes owed by a homeowner (in $) and the size of the home (in square feet) in an affluent suburb 30 miles outside New York City.

a. Estimate the sample regression equation that enables us to predict property taxes on the basis of the size of the home. (Round your answers to 2 decimal places.)

TaxesˆTaxes^ =  +  Size.

b. Interpret the slope coefficient.

• As Property Taxes increase by 1 dollar, the size of the house increases by 6.85 ft.

• As Size increases by 1 square foot, the property taxes are predicted to increase by $6.85.

c. Predict the property taxes for a 1,300-square-foot home. (Round coefficient estimates to at least 4 decimal places and final answer to 2 decimal places.)

1. A new entrepreneur wants to estimate the costs of an offsite team-building event for her 14 employees. She was able to gather the following information on a 3-day program in which she is interested. Use the unit technique to estimate the cost per employee of this event. Assume there will 100% participation in all activities.

Hans is a body-builder who owns and operates a health club in Freedonia, where he teaches body-building, weight-lifting, and strength exercises. In 1995, Hans wrote and obtained a copyright for a body-building manual entitled Pump You Up. In 2019, Hans learned that Franz, who lives and works in Sylvania (a state located 1,500 miles from Freedonia), was selling photocopies of Pump You Up over a website for profit without permission. Franz sold several copies of Pump You Up to Freedonia residents, gross Freedonia sales only $500.00 from 2004 to 2019.

Hans sues Franz in Freedonia court for copyright infringement, claiming that Franz is subject to personal jurisdiction in Freedonia bassed on Freedonia’s long-arm statute, which reads:

“A court may exercise personal jurisdiction over any non-domiciliary, or his executor or administrator, who in person or through an agent, transacts any business within the state or contracts anywhere to supply goods or services in the state.”

Franz has no office, employees, property, or bank accounts in Freedonia.

Does the Freedonia court have personal jurisdiction over Franz, making him subject to the lawsuit?

You have been looking around for a nice car and have found the car you want for the right price. All along, you have told the dealer that you want to purchase the car. It will cost you $45,000 out the door. You will put 25% down and take out a 4-year car loan. The interest rate you got from a local bank is 2.99% for 48 months.

You made the deal and now you need to “finalize” the paperwork with the dealer’s finance officer. He offers you an opportunity to lease the car and save you money every month! What a deal!! Here are the terms:

• Capitalized cost $4,500
• Lease payments $399
• Security deposit = 2 lease payments
• Lease term: 48 months
• Mileage cap: 10,000
• Mileage charge if over the cap: $0.25/mile
• Residual value: $22,500

Your savings account pays you 0.80% per year. You typically drive 13,000 miles per year. You plan on bringing the car back in perfect condition and expect to get your deposit back.

1. Based on pure numbers, should you buy or lease? Why?

Assume there is a certain population of fish in a pond whose growth is described by the logistic equation. It is estimated that the carrying capacity for the pond is 1000 fish. Absent constraints, the population would grow by 240% per year. If the starting population is given by p 0 = 600 , then after one breeding season the population of the pond is given by p 1 = After two breeding seasons the population of the pond is given by p 2 =

A company's sales in Seattle were $410,000 in 2012, while their sales in Portland were $285,000 for the same year. Complete the following statements:

a. Seattle's sales were % larger than Portland's.
b. Portland sales were % smaller than Seattle's.
c. Portland sales were % of Seattle's.

Give answers accurate to at least one decimal place.

Sound travels about 750 miles per hour. If you stand in a canyon and sound a horn, you will hear an echo.

Suppose it takes about 2.5 seconds to hear the echo. How far away is the canyon wall, in feet?
feet

Now let's generalize that result. Suppose it takes n seconds to hear the echo. How far away is the canyon wall, in terms of n?
   feet

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

PLEASE SHOW ALL YOUR WORK!

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.
