Dimethylhydrazine is a carbon-hydrogen-nitrogen compound used in rocket fuels. When burned in an excess of oxygen, a 0.312 g sample yields 0.458 gCO2 and 0.374 g H2O.
The nitrogen content of a 0.486 g sample is converted to 0.226 g N2.

The organic solvent thiophene is a carbon–hydrogen–sulfur compound that yields CO2, H2O, and SO2 on complete combustion. When subjected to combustion analysis, a 1.3020−gsample of thiophene produces 2.7224 g CO2, 0.5575 g H2O, and 0.9915 g SO2.

What is the empirical formula of thiophene?

A. Caspian Sea Drinks is considering the purchase of a new water filtration system produced by Rube Goldberg Machines. This new equipment, the RGM-7000, will allow Caspian Sea Drinks to expand production. It will cost $12.00 million fully installed and will be fully depreciated over a 20 year life, then removed for no cost. The RGM-7000 will result in additional revenues of $2.72 million per year and increased operating costs of $644,288.00 per year. Caspian Sea Drinks' marginal tax rate is 32.00%. If Caspian Sea Drinks uses a 9.00% discount rate, then the net present value of the RGM-7000 is _____.

B. Caspian Sea Drinks is considering buying the J-Mix 2000. It will allow them to make and sell more product. The machine cost $1.66 million and create incremental cash flows of $532,580.00 each year for the next five years. The cost of capital is 11.13%. What is the internal rate of return for the J-Mix 2000?

C. Caspian Sea Drinks is considering buying the J-Mix 2000. It will allow them to make and sell more product. The machine cost $1.90 million and create incremental cash flows of $642,799.00 each year for the next five years. The cost of capital is 11.97%. What is the profitability index for the J-Mix 2000?

1.) Company Zeta bought new office furniture in the year 2000. The purchase cost was 62426 dollars and in addition it had to spend 14941 dollars for installation. The furniture has been in use since April 21st, 2000. Zeta forecasted that in 2015 the office furniture would have a net salvage value of $1000. Using the US Accelerated Depreciation Schedule, estimate the value of depreciation recorded in the accounting books in the year 2004 if the company decided to sell the furniture on June 5th (of 2004). (note: round your answer to the nearest cent and do not include spaces, currency signs, or commas)

ANSWER: 3454.44

2.) Company Omega bought new petroleum refining equipment in the year 2000. The purchase cost was 174324 dollars and in addition it had to spend 14582 dollars for installation. The refining equipment has been in use since February 1st, 2000. Omega forecasted that in 2030 the equipment would have a net salvage value of $10,000. Using the US Straight Line Depreciation Schedule, estimate the value of depreciation recorded in the accounting books in the year 2004 if the company decided to sell the equipment on August 5th (of 2004).

ANSWER: 9445.3

1. Consider each of the following scenarios for profit maximizing firms operating in perfectly competitive markets. For each firm, state whether the firm should produce nothing, or increase, decrease, or maintain its output level.
   1. XYZ Corp. has output of 2000 units, market price = $64, average total cost = $62, average variable cost = $48, and marginal cost = $67.
   2. XYZ Corp. has output of 2000 units, market price = $64, average total cost = $70, average variable cost = $66, and marginal cost = $64.
   3. XYZ Corp. has output of 2000 units, market price = $64, average total cost = $64, average variable cost = $62, and marginal cost = $64.
   4. XYZ Corp. has output of 2000 units, market price = $64, average total cost = $62, average variable cost = $48, and marginal cost = $67.
   5. UVW Corp. has output of 6000 units, market price = $10, total costs = $72 000, total variable costs = $66 000, and marginal cost = $9.
   6. UVW Corp. has output of 10 000 units, market price = $4, total costs = $50 000, total variable costs = $30 000, and marginal cost = $4.

Select two data values from your raw data – one that is inside of the confidence interval and one that is outside – one must be at the high end of the data and one at the low end – and construct two hypothesis tests, one for each value. One of the tests should be a “less than”, the other should be a “greater than”, depending on the value being tested. Use a 95% level of confidence.
