The Manx Company was recently formed to manufacture a new product. It has the following capital structure in market value terms:
Debentures: $6,000,000
Preferred Stock: $2,000,000
Common Stock: $8,000,000
The company has a marginal tax rate of 40 percent. A study of publicity held companies in this line of business suggests that the required rate of return on equity isabout 17 percent (The CAPM approach was used to determine the required rate of return.) The Manx Company's debt is currently yielding 13 percent, and its perferredstock is yielding 12 percent. Compute the firm's present weighted cost of capital.

The amount of lateral expansion (mils) was determined for a sample of n = 9
The amount of lateral expansion (mils) was determined for a sample of n = 9 pulsed-power gas metal arc welds used in LNG ship containment tanks. The resulting sample standard deviation was s = 2.84 mils. Assuming normality, derive a 95% CI for ?2 and for ?. (Round your answers to two decimal places.)

A scientist notices that an oil slick floating on water when viewed from above has many different rainbow colors reflecting off the surface.
A scientist notices that an oil slick floating on water when viewed from above has many different rainbow colors reflecting off the surface. She aims a spectrometer at a particular spot and measures the wavelength to be 750 nm (in air). The index of refraction of water is 1.33.
Part A: The index of refraction of the oil is 1.20. What is the minimum thickness of the oil slick at that spot? t= 313nm
Part B: Suppose the oil had an index of refraction of 1.50. What would the minimum thickness be now? t=125nm
Part C: Now assume that the oil had a thickness of 200 nm and an index of refraction of 1.5. A diver swimming underneath the oil slick is looking at the same spot as the scientist with the spectrometer. What is the longest wavelength of the light in water that is transmitted most easily to the diver?

1. Langston Labs has an overall (composite) WACC of 10%, which reflects the cost of capital for its average asset. Its assets vary widely in risk, and Langston evaluates low-risk projects with a WACC of 8%, average projects at 10%, and high-risk projects at 12%. The company is considering the following projects:
Risk Expected Return
High 15%
Average 12
High 11
Low 9
Low 6

Consider a file currently consisting of 200 blocks. Assume that the file control block (and the index block, in the case of indexed allocation) is already in memory. Calculate how many disk I/O operations are required for contiguous, linked, and indexed (single-level) allocation strategies, if the following conditions hold. In the contiguous allocation case, assume that there is no room to grow in the beginning, but there is room to grow in the end. Assume that the block information to be added is stored in memory. For linked allocation, there is a tail pointer pointing to the last node.
- The block is added at the beginning
- The block is added at the end
- The block is removed from the beginning
- The block is removed from the end
More Assumptions:
-
Read one whole block = one I/O operation
-
Write one whole block = one I/O operation
-
For linked allocation, a file allocation table (FAT) is not used, i.e., only the address of the starting block is in memory
-
All preparation of a block (including putting in the data and any link value) is done in main memory and then the block is written to disk with one write operation
-
The file control block does not have to be written to disk after a change (this is typical where many operations are performed on a file)
-
At most one index block is required per file and it does not have to be written to disk after a change.
-
For contiguous, linked and indexed allocations, assume that no I/O operations are necessary to add a freed block to the free list
Note that while calculating the total number of I/O operations for each, also indicate how many came from r(read) and w(write).

A large-scale bakery is laying out a new production process for its packaged bread, which it sells to several grocery chains. It takes 12 minutes to bake the bread. How large of an oven is required so that the company is able to produce 4200 units of bread per hour (measured in the number of units that can be baked simultaneously)?
Consider the baggage check-in process of a small airline. Check-in data indicate that from 9 a.m. to 10 a.m., 240 passengers checked in. Moreover, based on counting the number of passengers waiting in line, airport management found that the average number of passengers waiting for check-in was 30. How long did the average passenger have to wait in line?

A copy machine is available 24 hours a day. On a typical day, the machine produces 88 jobs. Each job takes about 3 minutes on the machine, 2 minutes of which is processing time and 1 minute is setup time (logging in, defining the job). About 23 Percent of the jobs need to be reworked, in which case the setup time and the processing time have to be repeated. The remainder of the time, the equipment is idle. What is the OEE of the equipment?

A company reports accounting data in its financial statements. This data is used for financial analyses that provide insights into a company’s strengths, weaknesses, performance in specific areas, and trends in performance.
A company reports accounting data in its financial statements. This data is used for financial analyses that provide insights into a company’s strengths, weaknesses, performance in specific areas, and trends in performance. These analyses are often used to compare a company’s performance to that of its competitors or to its past or expected future performance. Such insight helps managers and analysts improve their decision making.
Consider the following scenario:
You work as an analyst at a credit-rating agency, and you are comparing firms in the construction and engineering sector. One company in the portfolio of companies you are analyzing is a Chinese firm. This firm stands out in the ratio analysis, because the company’s financial ratios are substantially lower than identical financial ratios of the other firms in the sector. You do not dissect the results of the ratio analysis and report this firm as an under-performing company.
Which of the following statements about your analysis report is true?
The analysis likely includes incorrect and misleading conclusions.
The ratios provide an accurate and thorough representation of the Chinese company’s performance.
