2. Swallows
3. Breathes quietly
4. Says “Tubs” at 350 Hz. List each phoneme separately. Next to each phoneme, state the intrinsic laryngeal muscle(s) and laryngeal nerve(s) activated

Using the following unit data for a company that produces Product A and B, what is the breakeven point (round to nearest unit) when fixed costs total $175,000?
Product A Product B
Units sold last year 2,250 1,000
Sales price $200 $450
Cost of goods sold   145   350
Sales commission     15     37
Variable costs   160   387
Contribution margin $ 40 $ 63

Suppose we are asked to decide whether a new project should be launched. We expect that cash flows over the five-year life of the project will be $350 million in the first two years, $375 million in the next two years, and $385 million in the last year. The initial investment is expected to cost $995 million.   The firm’s required return is 10%. Using a financial calculator, compute the NPV and IRR of this project.

Consider the following dataset taken for a field experiment (meansure in meters)

120 230 220 305 410 250 290 300 200 210 210 200 210 210 300 400 200 210 350 3000

a. Describe the distribution by computing:

i. Skweness. Interpret your result

ii. Kurtoisis. Interpret your result

b. is there an observation that may be an outlier? Explain?

Draw a boxplot for the distribution

Assume a bank with the following balance sheet at the end of the financial year.

Assets Amount Avg Duration (in years) Liabilities Amount Avg Duration (in years)

Reserves $100 0 Deposits $2000 1.5

T-notes $350 3 L T Debt $1000 15

Loans $1725 6 Equity $500 0

Mortgages $1325 12

Calculate the duration of assets and liabilities and the duration gap.

Air enters the turbine of a gas turbine at 1400 kPa, 1400 K, and expands to 100 kPa in two stages. Between the stages, the air is reheated at a constant pressure of 350 kPa to 1400 K. The expansion through each turbine stage is isentropic.

Determine:

(b) the heat transfer for the reheat process, in kJ/kg of air flowing.

(c) the increase in net work as compared to a single stage of expansion with no reheat.

Through the years criminologists have developed theories as to why humans commit crimes. However, it was not until Adler & Simon that attention has been consistently given to females and crime. (a) Discuss in detail one early criminologist’s view (pre-1950s) and one modern day (post-1950s) researcher’s work/research on females and crime.
