There are various depreciation methods that require an adjustment to Cost for the asset's estimated residual value. These are 1) Straight-line, 2) Units-of-Production, and 3) Sum-of-the-years-digits.

For Double-Declining, no adjustment to cost is made. The residual value is left un-depreciated at the end.

A New Truck had a cost of $35,000 and was expected to operate for five years. It is estimated to be worth $3,000 at the end of it's useful life of 100,000 miles. The truck was used 25,000 miles in year one and 20,000 in year two.

A) Under each of these methods what will be the book value of the truck at the end of it's useful life?
B) How much is year one's depreciation using sum-of-the year digits, unit-of-production and double-declining balance.

1.)Do heavier cars really use more gasoline? Suppose a car is chosen at random. Let x be the weight of the car (in hundreds of pounds), and let y be the miles per gallon (mpg). Write out the least-squares line y=a+bx

2.)Do heavier cars really use more gasoline? Suppose a car is chosen at random. Let x be the weight of the car (in hundreds of pounds), and let y be the miles per gallon (mpg). The estimate y value found in the previous question is _____ (answers are either: an extrapolation, an interpolation, an error, or a residual)

George and June are active volunteers in their local church. George serves as an usher one Sunday morning a month. June sings in the church choir every Sunday morning and attends choir practice each Wednesday evening. Based on the distance from their home to church, June drives 500 miles a year to attend choir practice and sing on Sunday. George leaves home by himself to arrive at church early on the mornings he serves as an usher and put 120 miles on his car this year on these trips. June paid $1,000 for singing lessons to improve her voice so that she might be chosen to sing a solo at church. Are any of these expenses related to serving as an usher or singing in the church choir deductible by George or June?

A researcher is interested in evaluating a certain brand of radial auto tire. Twenty tires are randomly selected from retail outlets throughout the country, and each is placed on a special machine which rotates the tires at a constant speed (equivalent to 55 miles per hour) against the friction equivalent of a 4000 pound auto being driven on a smooth highway. Each tire is run until there is no tread left. The number of miles (in thousands) were as follows: 40, 30, 32, 35, 39, 35, 31, 36, 37, 35, 34, 35, 37, 34, 36, 38, 35, 36, 35, 36.

Setting alpha at .01, test the hypothesis that this sample of tires could represent a population whose mean was 36.50.

A tire manufacturer claims that the life span of its tires is 52,000 miles. Assume the life spans of the tire are normally distributed. You selected 16 tires at random and tested them. The mean life span of the sample is 50,802 miles. The tires had a population standard deviation, σ = 800. Use the .05 level of significance. a) Which distribution would be indicated? b) Explain why you chose that distribution. c) Construct a confidence interval for the mean using the above data. Use the .05 level of significance. d) Re-compute the confidence interval if “n” is increased to 125 with the same mean and standard deviation. e) Re-compute the confidence interval if level of significance .01 with the same mean and standard deviation with the original n.

Ilya and Anya each can run at a speed of 8.30mph and walk at a speed of 3.90mph . They set off together on a route of length 5.00miles . Anya walks half of the distance and runs the other half, while Ilya walks half of the time and runs the other half.

How long does it take Anya to cover the distance of 5.00miles ?

Express your answer numerically, in minutes.

Find Anya's average speed.

Express Anya's average speed save,Anya numerically, in miles per hour.

How long does it take Ilya to cover the distance?

Express the time tIlya taken by Ilya numerically, in minutes.

Now find Ilya's average speed.

Express Ilya's average speed save,Ilya numerically, in miles per hour.

Suppose you observe the following information: The stock of Besl Baseball Statistics has a beta of 0.3, and an expected return of 5.25%. The stock of Bannon Buybacks has a beta of 1.2, and an expected return of 16.5%. Based on the Capital Asset Pricing Model, what is the market risk premium?

Determine the entrance conditions at the hub of an axial flow stator-rotor compressor. The mean-velocity diagram has a flow coefficient of 0.3 and work coefficient of 0.446. The exit flow is at axial direction. The hub diameter is 0.75 of the mean diameter. The axial flow velocity has a relationship
