Java

Write a valid Java method called printReverse that takes a String as a parameter and prints out the reverse of the String. Your method should not return anything. Make sure you use the appropriate return type.

Economic 315: Money, Banking and Financial Market

1. Is there any relationship between increase in corporate debt and corporate investing? Explain.

2. What is the alternative to investing that money in their corporations?

3. What is the purpose of stock buybacks?

4. Do you think stock buybacks are the good for the economy? Why or why not?

When discussing CFCs (chlorofluorocarbons), what are the properties of that chemical (such as water solubility, vapor pressure, etc.) that determines its migration in our environment?

The Path to Good Ethics Starts in Human Resources. Do you agree or disagree with this statement? Please explain in detail and provide examples.

1. Suppose that each day, Northern, Central, and Southern California each use 100 billion gallons of water. Also assume that Northern California and Central California have available 120 billion gallons of water, whereas Southern California has 40 billion gallons of water available. The cost of shipping 1 billion gallons of water between the three regions is as follows. Also, you will not be able to meet all the demand for water, so assume that each billion gallons of unmet demand incurs the following shortage costs:

How should California’s water be distributed to minimize the sum of shipping and shortage costs and what is the total cost?

1. You are to do a preliminary design study for a small demonstration steam turbine power plant.
- Steam will be provided by a small steam generator fired by natural gas.   - Your system will take in steam at 30 bar and 400 oC.
- The steam passes through a two stage turbine. At a pressure of 10 bars, the steam leaves the first stage of the turbine and will pass through a reheat loop in the steam generator which will boost the temperature back up to 400 oC at this pressure. The steam will then enter the second stage of the turbine.
- When the steam leaves the turbine, the quality should be at least 95% at the turbine exit / condenser inlet.
- The design condenser pressure is 0.70 bar.   
- Heat is removed from the condenser and rejected to the environment through a cooling tower.
a) Assuming isentropic expansion, what are the temperature, enthalpy, and entropy of the steam when it leaves the first stage of the turbine? (5 pts)

b) What are the enthalpy and the entropy of the steam as it leaves the reheater and enters the second stage of the turbine? How much heat (kJ/kg) goes into the steam in the reheat process? (10 pts)

c) Based on an isentropic expansion, what will the quality be at the exit? Will it meet this design limit? (10 pts)
For the following parts use the design turbine power output of 2.5 kW.
d) What mass flow rate is required? (10 pts)

e) At what rate must heat be produced by natural gas burners in the steam generator to produce the steam at the turbine inlet, and how much heat must be produced to reheat the steam between the stages? For a heating rate range of 950-1150 BTU/scf and a cost of $8 per 100 cubic feet, what is the fuel cost per hour to run this unit? (10 pts)

f) What is the feed water pump power demand, and what is the BWR? (10 pts)

For your string use the same format as below! 1: 1892 Traditional Bid: 14 by Juliet (female, 27) 2: Iceberg Lager No bid 3: Rhinegold Altbier Bid: 17 by William (male, 22).

Nickel metal will react with CO gas to form a compound called nickel tetracarbonyl (Ni(CO₄)) which is gas at temperatures above ~45C.

A 1.50 L glass bulb is filled with CO gas to a pressure of 1.20 atm at 73C and then 0.5869 g is pure Ni is added. If the reaction described above occurs and goes to completion at constant temperature, what will the final total pressure in the bulb be?

In what follows use any of the following tests/procedures: Regression, confidence intervals, one-sided t-test, or two-sided t-test. All the procedures should be done with 5% P-value or 95% confidence interval.

Use the Weight_vs_IQ data. SETUP: Common sense dictates that a person’s IQ and Weight should not be related. However, one never knows until one examines the data. Given the data (IQ and weight for 29 students) your job is to check if the common sense assumption is reasonable or maybe it is not.

13. What test/procedure did you perform?

• a. One-sided t-test
• b. Two-sided t-test
• c. Regression
• d. Confidence interval

14. What is the P-value/margin of error?

• a. 0.749971
• b. 8.2E-06
• c. 0.711936
• d. 0.355968

15. Statistical interpretation

• a. Since the P-value is very small, we can confirm the common sense assumption that IQ and Weight are not related.
• b. Since the P-value is large, we cannot claim that averages are different.
• c. Since the P-value is large, we cannot claim that IQ and Weight are related.
• d. None of these.

16. Conclusion

• a. I have no statistical evidence to claim that IQ and Weight are related.
• b. I am confident that IQ and Weight are related.
• c. I am confident that IQ and Weight are not related.

1. Consider the implications of two recent headlines: "Fiat Chrysler Shares Crash by a Fifth as it is Drawn into Emissions Scandal by US Regulators" and "FBI Arrests Volkswagen Executive emissions Scandal." it appears that Fiat Chrysler and Volkswagen not only failed to act responsibly to comply with emissions regulations but they also committed fraud to make government officials and the public believe they were in compliance. Do you think Fiat Chrysler and Volkswagen are regretting the decisions they made in the past to avoid compliance costs? What costs are they paying now?
