Using the table below, indicate which scale of measurement (nominal, ordinal, interval/ratio) is most appropriate for the variable indicated.

A 4-year 12% coupon bond has a yield of 10%.

a) What are its Macaulay Duration, Modified duration, and convexity

b) What is the actual price change, Modified Duration predicted price change and Modified Duration + convexity predicted change in price for an increase of 50 basis point in the yield.

Assume a flat term structure before and after the increase and annual coupons.

Provide an example of how to REVISE straight line depreciation on an existing asset when there is a CHANGE in estimated useful life or salvage value by addressing the following points:

1.  How many years of depreciation have already been recorded?  

2.  What is the revision in useful life or salvage value?

3.  What was depreciation expense per year BEFORE AND AFTER the revision?

Outline the steps to calculate the initial pH in the titration of a strong acid with a strong base?

Outline the steps to calculate the pH before the equivalence point of the titration of a strong acid with a strong base?

Outline the steps to calculate the pH after the equivalence point of the titration of a strong acid with a strong base?

What is the pH halfway to the equivalence point of the titration of a weak base with a strong acid?

A rock is thrown with an initial velocity of 30 m/s at an angle of 60° above the horizontal from a height of 1.5 m toward a cliff. After 4 seconds, the rock lands on the top edge of the cliff.

(a) Calculate the height of the cliff.

(b) Calculate the maximum height reached by the rock along its trajectory

(c) Determine the speed of the rock just before hitting the cliff.

Governments are in the business of providing information to potential buyers. The first serious provision of information on the health consequences of tobacco use appeared in the United States Report of the Surgeon General in 1964. (a) How would you represent this intervention in a supply and demand for tobacco diagram? Draw a graph to compare the outcomes before and after the intervention. (b) Did this intervention correct a market failure? Briefly explain.

Identify a popular/common computer related product/solution that utilizes an interface that are not optimal for human interaction. It must clearly identify the original problem that lead to the development of the solution. Describe how the users resolve the problem before the solution was developed and after the development of the solution. Explain why you think the solution is not optimal and how to improve the solution to provide a better interface for human interaction.

A factory worker’s union is appealing to the factory management for more vacation time for its employees. The union claims that the workers are more productive when they come back from vacation than before (in other words, that production rate and vacation status are related). The following table contains the production rates, measured in units per hour, for a sample of employees. The union feels that it needs to be 90% confident (level of significance = 0.10) before going into talks with the employers. Does the union have strong enough evidence to support its claim?

Conclusion:

A child hits an ice cube with a mass of 10 grams on a table with a force of 10 N. The impact lasts 0.02 seconds. The ice cube flies off the table, which is 1 meter high and lands some distance away. Assume there is no friction between the ice cube and the table.

a. What is the velocity of the ice cube when it leaves the table?

b. What is the final velocity of the ice cube just before it hits the floor?

c. What is the momentum of the ice cube just before it hits the floor?

d. What distance will the ice cube land from the foot of the table?

e. Suppose the ice cube had broken into two pieces just after the child hit the ice and moved away from each other while falling to the floor. How would the total momentum of the two pieces just before they hit the floor compare to the momentum you found in part (c)?

Mongo Inc. needs someone to supply it with 200,000 cartons of machine screws per year to support its manufacturing needs over the next 5 years, and you've decided to bid on the contract. It will cost you $1,200,000 after-tax to install the equipment necessary to start production; you'll depreciate this cost straight-line to zero over the project's life. You estimate that in 5 years, this equipment can be salvaged for $75,000 before-tax. Your fixed production costs will be $350,000 before-tax per year, and your variable production costs should be $12.00 before-tax per carton. You also need an initial increase in account receivables of $100,000 and a decrease in account payable of $150,000, all of which will be recovered when the project ends. Your tax rate is 20 percent and you require a 10 percent return on your investment. What bid price per carton should you submit?
