Discuss the structure of a Java™ program including files and arrays with GUI.

How do iterative structures differ from conditional structures in OOP?

Provide an example.

The following data were taken from the balance sheet of Nilo Company at the end of two recent fiscal years:

a. Determine for each year (1) the working capital, (2) the current ratio, and (3) the quick ratio. Round ratios to one decimal place.

b. The liquidity of Nilo has   from the preceding year to the current year. The working capital, current ratio, and quick ratio have all  . Most of these changes are the result of an   in current assets relative to current liabilities.

(1) name a branded example, then (2) hypothesize about how you might categorize customers by their different needs, and (3) how the company offers values/benefits to meet those needs for each categorized customers.

• Air travel transportation (B2C) (20 points)
• Computer software (B2C) (20 points)

1-Give a BNF grammar (do not use EBNF) for the language that generates the set of all strings consisting of the keyword begin, followed by zero or more statements with a semicolon after each one, followed by the keyword end. Use the non-terminal for statements, and do not give productions for it.

2-Give a BNF grammar (do not use EBNF) for the language that generates the set of all strings consisting of the keyword begin, followed by one or more statements with a semicolon after each one, followed by the keyword end. Use the non-terminal for statements, and do not give productions for it.

3-Give a BNF grammar (do not use EBNF) for the set of all strings consisting of zero or more as, with a comma between each a and the next. (There should be no comma before the first or after the last.)

4-Give a BNF grammar (do not use EBNF) for the set of all strings consisting of an open bracket (the symbol [) followed by a list of zero or more digits separated by commas, followed by a closing bracket (the symbol ]).

Execusmart Consultants has provided business consulting services for several years. The company has been using the percentage of credit sales method to estimate bad debts but switched at the end of the first quarter this year to the aging of accounts receivable method. The company entered into the following partial list of transactions.

1. During January, the company provided services for $350,000 on credit.
2. On January 31, the company estimated bad debts using 1 percent of credit sales.
3. On February 4, the company collected $175,000 of accounts receivable.
4. On February 15, the company wrote off a $450 account receivable.
5. During February, the company provided services for $300,000 on credit.
6. On February 28, the company estimated bad debts using 1 percent of credit sales.
7. On March 1, the company loaned $16,000 to an employee, who signed a 9% note due in 3 months.
8. On March 15, the company collected $450 on the account written off one month earlier.
9. On March 31, the company accrued interest earned on the note.
10. On March 31, the company adjusted for uncollectible accounts, based on the following aging analysis, which includes the preceding transactions (as well as others not listed). Prior to the adjustment, Allowance for Doubtful Accounts had an unadjusted credit balance of $9,000.

Required:

1. For items (a)–(j), analyze the amount and direction (+ or –) of effects on specific financial statement accounts and the overall accounting equation. TIP: In item (j), you must first calculate the desired ending balance before adjusting the Allowance for Doubtful Accounts. (Do not round intermediate calculations. Enter any decreases to Assets, Liabilities, or Stockholders Equity with a minus sign.)

Why does titrimetric end-group analysis become impractical for determining the M_n of polymers whose average molecular weight exceeds about 25000?

A power network involves three substations A, B, and C. Overloads at any of these substations might result in a blackout of the entire network. Past history has shown that if substation A alone experiences an overload, then there is a 1% chance of a network blackout. For stations B and C alone these percentages are 2% and 3%, respectively. Overloads at two or more substations simultaneously result in a blackout 5% of the time. During a heat wave there is a 64% chance that substation A will experience an overload, a 24% chance that substation B will experience an overload, and a 19% chance that substation C will experience an overload. There is a 3% chance that exactly two of the substations will simultaneously experience overload, and it is equally likely to be any two of the three. Finally, there is a 2% chance that all three substations experience an overload.

a) What is the probability that a blackout due to an overload occurs during a heat wave?

b) If a blackout occurred during a particular heat wave, what is the probability that the substation A alone experienced an overload?

c) If a blackout occurred during a particular heat wave, what is the probability that an overload occurred at two or more substations simultaneously?

Thank you!

Using a text editor or IDE, copy the following list of names and grade scores and save it as a text file named scores.txt:
Name, Score
Joe Besser,70
Curly Joe DeRita,0
Larry Fine,80
Curly Howard,65
Moe Howard,100
Shemp Howard,85
Create a JavaScript program of the files that display high, low, and average scores based on input from scores.txt. Verify that the file exists and then use string functions/methods to parse the file content and add each score to an array. Display the array contents and then calculate and display the high, low, and average score. Format the average to two decimal places. Note that the program must work for any given number of scores in the file. Do not assume there will always be six scores and use Node Js as IDE.

Identified demand and supply shifters for your product. Choose one demand and one supply factor. Sketch two SD diagrams to illustrate how an increase in this factor will shift D or S curves, and what happens to the market P and Q in each case. Explain briefly.

The table below provides several temperature values taken at various altitudes

Altitude(in the thousands of feet) 3 10 14 22 28 31 33

Temperature                           57 37 24 -5 -30 -41 -54

Determine if there is linear correlation between altitude and temperature. Give the appropriate r-value(do not calculate this value by hand) and what values you used to determine if there was or was not correlation. Conduct a hypothesis test at the 0.05 level of significance and List the equation of best fit(found via technology) and use this equation to find the predicted temperature at 6327 feet(show the calculation).

1. Give several examples of cogeneration and heat pumps. Describe how they work and why they save energy.
2. Can the waste heat from nuclear plants do useful work? What happens to the wasteheat from power plants? How do the First and Second Laws of Thermodynamics apply to these processes?
3. Find numerical examples of energy usage and thermodynamic computations of efficiency. Use the web to compare the efficiencies of several power production processes. Which are in use and which are planned?

Imagine a set Implementation which uses heaps, instead of binary search trees. How would performance of such a data structure differ from a set Implementation using Balanced Trees(AVL or Red/Black Trees)? Performance meaning RunTime(Time complexity) of the methods in the data structure ex. add()

Organic food is grown without synthetic pesticides, chemical fertilizers or genetically modified seeds. In recent decades, the demand for organic products has increased dramatically. The Organic Trade Association reported sales increased from $1 billion in 1990 to $31.5 billion in 2011, more than 90% of which were sales of food products.

Why, then, are organic foods more expensive than their conventional counterparts? The answer could be an application of the supply and demand model. Describe in your own words what factors have affected and will continue to affect the demand and supply for organic foods? Describe any shifts, and make any predictions of what might happen to the prices of organic foods in the future.
