Problem 8-34A Accounting for depletion LO 8-7, 8-9

Flannery Company engages in the exploration and development of many types of natural resources. In the last two years, the company has engaged in the following activities:

**Prepare the portion of the December 31, Year 2, balance sheet that reports natural resources. Assume that in Year 3 the estimates changed to reflect only 60,680 tons of gold ore remaining. Prepare the depletion journal entry in Year 3 to account for the extraction of 42,476 tons of gold ore.** I completed part A

a. Prepare the journal entries to account for the following:

1. (1) The Year 1 purchases.
2. (2) Depletion on the Year 1 purchases, assuming that 73,000 tons of silver were mined and 989,000 board feet of lumber were cut.
3. (3) The Year 2 purchases.
4. (4) Depletion on the four natural resource assets, assuming that 60,000 tons of silver ore, 1,176,000 board feet of lumber, 8,900 tons of gold ore, and 80,000 barrels of oil were extracted.

repare the journal entries to account for the following:

1. (1) The Year 1 purchases.
2. (2) Depletion on the Year 1 purchases, assuming that 73,000 tons of silver were mined and 989,000 board feet of lumber were cut.
3. (3) The Year 2 purchases.
4. (4) Depletion on the four natural resource assets, assuming that 60,000 tons of silver ore, 1,176,000 board feet of lumber, 8,900 tons of gold ore, and 80,000 barrels of oil were extracted. (Round all cost estimated to 2 decimal places and final answers to the nearest dollar amount. Enter depletion expenses in the given order. If no entry is required for a transaction/event, select "No journal entry required" in the first account field.)

At the significance level of 0.05, are the drug concentrations in Group A and Group B different? Using the most appropriate t test.

You purchase 50 shares for $50 a share ($2,500), and after a year the price falls to $40. Calculate the percentage return on your investment if you bought the stock on margin and the margin requirement was (ignore commissions, dividends, and interest expense):

1. 25 percent. Use a minus sign to enter the amount as a negative value. Round your answer to one decimal place.

     %

2. 65 percent. Use a minus sign to enter the amount as a negative value. Round your answer to one decimal place.

     %

3. 80 percent. Use a minus sign to enter the amount as a negative value. Round your answer to one decimal place.

A researcher believes that 8% of pet dogs in Europe are Labradors. If the researcher is right, what is the probability that the proportion of Labradors in a sample of 630 pet dogs would be greater than 7%? Round your answer to four decimal places.

My question is since the z table is 0.925 would I add up both scores and then divide by two? Or would I just round up?

The following is a set of data from a sample of n = 11 items: X 8 6 9 4 7 11 13 5 10 16 19 Y 22 15 25 10 19 31 37 13 27 45 54 a. Calculate the covariance. b. Calculate the coefficient of correlation. c. Describe the relation between the two variables X and Y.

Based on the data shown below, calculate the regression line (each value to two decimal places)

y =  x +

Problem #3

Company needs to decide between two machines.

Machine C costs 10,000 and produce after tax cash flows of 4,000 per year for 3 years. No salvage.

Machine D costs 14,000 and produce after tax cash flows of 3,000 per year for 7 years. No salvage.

Discount rate is 8%

Which machine would you recommend?

Consider the following bond: Face value = 1000; coupon rate = 8%; maturity = 5 years; ytm = 7%

A) What is the value of the bond today and in 2 years?

b) what are the current yield and capital gains yield for this bond this year and in two years?

c) Assuming interest rates remain the same over this bond's lifetime, what is going to happen to the value of this bond as time goes by?

The reservation office for Central Airlines has two agents answering incoming phone calls for flight reservations. A caller can be put on hold until one of the agents is available to take the call. If all three phone lines (both agent lines and the hold line) are busy, a potential customer gets a busy signal, in which case the call is lost. All calls occur randomly (i.e., according to a Poisson process) at a mean rate of 15 per hour. The length of a telephone conversation has an exponential distribution with a mean of 4 minutes.

(a)Construct the rate diagram for this queueing system.

(b) Find the steady-state probability that:

(i) A caller will get to talk to an agent immediately.

(ii) The caller will be put on hold, and

(iii) The caller will get a busy signal.
