Assignment Purpose

The purpose of this lab is to write a well commented java program that demonstrates the use and re-use of methods with input validation.

Instructions

1. It is quite interesting that most of us are likely to be able to read and comprehend words, even if the alphabets of these words are scrambled (two of them) given the fact that the first and last alphabets remain the same. For example,

“I dn'ot gvie a dman for a man taht can olny sepll a wrod one way.” (Mrak Taiwn)

“We aer all moratls, Hamrbee is an immoratl, and tehre is no question abuot it.” (Kevin Unknown)

2. Write a method named scramble that returns a String and takes a String as an argument.
   1. The argument is actually a word (of length 6 or more).
   2. It then constructs a scrambled version of that word, randomly flipping two characters other than the first and last one.
3. Then write the main method in which you would read the word from the user, send it to scramble, and print the scrambled word.
   1. You can use a loop to read multiple words if you like but it is not necessary.
   2. If the length of the entered word is less than 6, you should keep prompting the user to enter a valid word.
4. After writing all the comments, generate a Javadoc and submit it with the java file.

Hint: First generate two random integers in range of the length of the string. Then use substring method to access characters at those locations. Rest is left to your imagination.

Two hundred kg of liquid contains 40% pentane, and rest hexane. Pentane MW is 72.15 g/ gmol and SG (20C/4C) is 0.17. Hexane MW is 86.17 g/ gmol and SG (20C/4C) is 0.659. Determine a) the total number of moles, b) the mole fraction composition of the liquid, c) the average molecular weight and d) the average density of the solution.

Springfield Corporation, whose tax rate is 40%, has two sources of funds: long-term debt with a market value of $10,000,000 and an interest rate of 8%, and equity capital with a market value of $10,000,000 and a cost of equity of 13.2%. Springfield uses its weighted average cost of capital to calculate the EVA for its Dallas division. For the latest year, the Dallas division had a NOPAT of $250,000, total assets of $1,000,000 and current liabilities of $200,000. The division’s EVA is:

Excel Hydro took a loan contract which requires a payment of $40 million plus interest two years after the contract's date of issue. The interest rate on the $40 million face value is 9.6% compounded quarterly. Before the maturity date, the original lender sold the contract to a pension fund for $43 million. The sale price was based on a discount rate of 8.5% compounded semi-annually from the date of sale.

Excel Hydro is also considering building a nuclear power plant, which will be ready for production in 2030. The country's governing body is also considering a decommissioning liability law for the operator to put aside $1 million every month towards decommissioning cost. If the production life of the plant is 60 years and the operator puts the money at the end of the month in a savings account, earning 7.25% compounded monthly.

During the 60 years of production life of the plant, the operator will put $1 million at the end of the month in a savings account, earning 7.25% compounded monthly. At the end of the production life of the plant, there are no more contributions and the money is expected to grow at the rate of 6% compounded quarterly for the next 30 years.

Explain what the Vice President can legitimately do now to help accomplish this goal. Provide specific examples in your answer.

1) A book manufacturing company has two different production plants, plant A and plant B. 40% of books come from plant A. Of the books that come from plant A 30% are defective and 70% work as intended. Of the books from plant B 10% are defective and 90% work as intended. On top of this 10% of the defective books from plant A explode.

A) Draw a tree diagram of this data.

B) What is the probability of randomly selecting

C) What is the probability of randomly selecting adefective book which doesn’t explode?

3.5.12 Suppose there are two urns. Urn I contains 100 chips: 30 are labelled 1, 40 are labelled 2, and 30 are labelled 3. Urn 2 contains 100 chips: 20 are labelled 1, 50 are labelled 2, and 30 are labelled 3. A coin is tossed and if a head is observed, then a chip is randomly drawn from urn 1, otherwise a chip is randomly drawn from urn 2. The value Y on the chip is recorded. If an occurrence of a head on the coin is denoted by X = 1, a tail by X = 0, and X ∼ Bernoulli(3/4), then determine E(X | Y), E(Y | X), E(Y), and E(X)

your firm is considering two financing plans. The key information follows: use a 40% tax rate
