Write a Java program which reads a positive integer from the command line, then displays the sum of all even values up to and including the value provided, followed by the sum of all odd values up to and including the value provided.

• validate that the command line argument is an integer greater than 0
• to validate the type, you can use Integer.parseInt() with a try/catch for NumberFormatException
• use one or more for loops to perform the even and odd sum calculations

Expected console output follows. Command line argument shown in red. Output was generated by multiple runs of the program to test input validation.

D:\COP2800C> java Sums 0
Value entered is 0
0 is out of range.

D:\COP2800C> java Sums -1
Value entered is -1
-1 is out of range.

D:\COP2800C> java Sums 5.5
Value entered is 5.5
5.5 is not an integer.

D:\COP2800C> java Sums hello
Value entered is hello
hello is not an integer.

D:\COP2800C> java Sums 5
Value entered is 5
The sum of the even numbers up to 5 is 6
The sum of the odd numbers up to 5 is 9

5) Name the data model that is only used to document a database design.

6) State the most important characteristics regarding the output of any relational algebra operation.

7) Name the software system that permits the data in a distributed database to be transparent to others.

8) Use two words to distinguish a file based system and a database.

With C++,

1. Assume we use two linked lists that represent Set A and Set B respectively. Implement the
following function to calculate A = A U B. Note that a SET should not contain duplicated
elements (e.g., integers).

void unionLL (Node * LA, Node * LB);

2. There are two linked lists, LA and LB. Their elements are both in the non-descending order.
Implement the following function to merge LA and LB into a new linked list, LC. Make sure that
the elements in LC are still in the non-descending order. (50 Points)

void mergeLL (Node * LA, Node * LB, Node * LC);

Example:
LA = (3, 5, 8, 11)
LB = (2, 6, 8, 9, 22, 24)
Then:
LC = (2, 3, 5, 6, 8, 8, 9, 11, 22, 24)

Additional requirements:
1. Create a main function and print out the numbers in the linked lists before and after
executing each method above.

2. Assume Node is defined as follows:
struct Node{
int num;
Node * next;
};

Any help appreciated.

We assume that our wages will increase as we gain experience and become more valuable to our employers. Wages also increase because of inflation. By examining a sample of employees at a given point in time, we can look at part of the picture. How does length of service (LOS) relate to wages? The data here (data393.dat) is the LOS in months and wages for 60 women who work in Indiana banks. Wages are yearly total income divided by the number of weeks worked. We have multiplied wages by a constant for reasons of confidentiality.

(a) Plot wages versus LOS. Consider the relationship and whether or not linear regression might be appropriate. (Do this on paper. Your instructor may ask you to turn in this graph.)

(b) Find the least-squares line. Summarize the significance test for the slope. What do you conclude?

(c) State carefully what the slope tells you about the relationship between wages and length of service.


(d) Give a 95% confidence interval for the slope.

The comparative statements of financial position for 2023 and 2022 and the statement of profit or loss for 2023 are given below for Dux Company. Additional information from Dux's accounting records is also provided.

Additional information from the accounting records:

1. A building that originally cost $40,000, and which was three-fourths depreciated, was sold for $7,000.
2. The ordinary shares of Byrd Corporation were purchased for $5,000 as a long-term investment.
3. Property was acquired by issuing a 13%, seven-year, $30,000 note payable to the seller.
4. New equipment was purchased for $15,000 cash.
5. On January 1, 2023, bonds were sold at their $25,000 principal amount.
6. On January 19, Dux issued a 1-for-20 bonus issue (1,000 ordinary shares). Assume that the bonus issue was valued at the market price of $14 per share ($10 par value) at that time, and the corporation law requires a reclassification from retained earnings to issued capital.
7. Cash dividends of $13,000 were paid to shareholders.
8. On November 12, 500 ordinary shares were repurchased as treasury shares at a cost of $8,000.

Required:
Prepare the statement of cash flows for Dux Company using the indirect method, assuming Dux classifies dividend revenue and interest paid as operating activities and dividends paid as a financing activity. (Do not round intermediate calculations. Amounts to be deducted should be indicated with a minus sign. Enter your answers in thousands. (i.e., 10,000 should be entered as 10).)

7. A certain sports car model has a 0.07 probability of defective steering and a 0.11 probability of defective brakes. Erich S -E just purchased one of the models. If the two problems are statistically independent, determine the probability

a. Erich’s car has both defective steering and defective brakes.

b. Erich’s car has neither defective steering nor defective brakes.

c. Erich’s car has either defective steering only or defective brakes only (meaning exactly one of the two, but not both, defects).

A beaker with 130 mL of an acetic acid buffer with a pH of 5.00 is sitting on a benchtop. The total molarity of acid and conjugate base in this buffer is 0.100 M. A student adds 6.20 mL of a 0.490 M HCl solution to the beaker. How much will the pH change? The pKa of acetic acid is 4.760.

Express answer numerically to two decimal places. Use a minus (-) sign if the pH has decreased.

Given the year end prices of the following stocks, estimate the expected return of a portfolio of 30% AAA and 70% BBB. Enter your answer as a percent without the % sign. Round your final answer to two decimals.

Jeff and Sylvia Chan are now both 71 years of age and they have been retired for seven years. They have managed to remain debt free since their retirement seven years ago and their cash flow is now positive. Sylvia received a $1,000,000 inheritance shortly after their planned retirement and the funds were used exclusively to fund their retirement over the last six years. There is still $500,000 left from this amount and it is currently sitting in her bank account earning very little interest. Sylvia would like some recommendations on how to invest these funds. Her objective is to generate a 6% return on investments that are moderate risk and can provide a tax credit. She understands that 4% of this income will relate to dividend yield and 2% to deferred capital gains. Their RRSPs continued to grow since Jeff and Sylvia were age 65 and they have not taken any withdrawals. The plans were worth $600,000 and $700,000 respectively.

Since they are 71 years of age and must start withdrawing their RRSP funds as per the maturity rules they will be taking the minimum amount from their RRIF staring at age 72. In addition to this income they will have maximum CPP and maximum OAS, the amounts of which increased since they have deferred withdrawal. They also want to leave a significant estate for their two children. The current market value of the principal residence is $1,200,000. Jeff also has an investment property that transferred over to him at a fair market value of $400,000 when his dad died five years ago. The property is current valued at $500,000 and he expects that both the investment property and the principal residence will increase in value at 7% per year. The investment property generates $12,000 of additional rental income per year before deductions for property taxes which are $3,000, and property insurance of $1,200 per year. There is no mortgage on either property.

Their primary residence is held in joint tenancy and they have designated each other as beneficiary on their RRIF accounts. The inheritance account will be held solely in Sylvia’s name and the investment property solely in Jeff’s name.

REQUIRED –

How would you recommend Sylvia invest her remaining $500,000 inheritance given her objective for income with moderate risk and tax credits? (2) Recommend at least two different mutual funds and provide details on the mutual fund’s investment objective, performance, management fees and volatility.
