LIFO Perpetual Inventory

The beginning inventory of merchandise at Rhodes Co. and data on purchases and sales for a three-month period ending June 30 are as follows:

Required:

1. Record the inventory, purchases, and cost of merchandise sold data in a perpetual inventory record similar to the one illustrated in Exhibit 4, using the last-in, first-out method. Under LIFO, if units are in inventory at two different costs, enter the units with the HIGHER unit cost first in the Cost of Merchandise Sold Unit Cost column and LOWER unit cost first in the Inventory Unit Cost column.

3. Determine the ending inventory cost on June 30.

In a study examining the survival of cancer patients, 100 patients were enrolled at baseline. After one year, 20 patients were known to have died. Assuming no patients were lost to follow-up, what was the probability of surviving one year? (OK to show numerator/denominator)What would be the one-year survival rate in the previous question if ten patients had been lost to follow-up during the first year? Use the life table method.

A 4.0-cm-diameter parallel-plate capacitor with a 1.0 mm spacing is charged to 1000 V. A switch closes at t =0s, and the capacitor is discharged through a wire with 0.20? resistance.

Part A

Find an expression for the magnetic field strength inside the capacitor at r =1.0cm as a function of time t (where t is in ps).

Part B

Draw a graph of B versus t.

Mark Ventura has just purchased an annuity to begin payment two years from today. The annuity is for $24,000 per year and is designed to last 7 years. If the interest rate for this problem calculation is 11 percent, what is the most he should have paid for the annuity? Use Appendix B and Appendix D for an approximate answer, but calculate your final answer using the formula and financial calculator methods. (Do not round intermediate calculations. Round your final answer to 2 decimal places.) Maximum Payment =

An insurance company divided its clients into two categories, amateur and professional. The last year accident report shows 10% of amateur drivers and 2.5% of professional drivers are involved in an accident. If 15% of drivers are amateur license and 85% are professional, find the following probabilities. For simplicity, assume year to year accident accidents for any driver are independent.

1. a) What is the probability of accident for a driver?
2. b) What is the probability that an amateur driver is involved in at least one accident during 3 years?
3. c) What is the probability of not having an accident for a professional driver during 3 years?
4. d) The annual insurance premium is computed according to being involved to at least one accident in 3 years. If a professional driver pay $1000 premium, how much the premium of amateur drivers should be?

An instructor who taught two sections of engineering statistics last term, the first with 25 students and the second with 30, decided to assign a term project. After all projects had been turned in, the instructor randomly ordered them before grading. Consider the first 15 graded projects.

(b) What is the probability that at least 10 of these are from the second section? (Round your answer to four decimal places.)


(c) What is the probability that at least 10 of these are from the same section? (Round your answer to four decimal places.)


(d) What are the mean value and standard deviation of the number among these 15 that are from the second section? (Round your mean to the nearest whole number and your standard deviation to three decimal places.)

(e) What are the mean value and standard deviation of the number of projects not among these first 15 that are from the second section? (Round your mean to the nearest whole number and your standard deviation to three decimal places.)
