Periodic Inventory by Three Methods

Dymac Appliances uses the periodic inventory system. Details regarding the inventory of appliances at January 1, purchases invoices during the next 12 months, and the inventory count at December 31 are summarized as follows:

Required:

1. Determine the cost of the inventory on December 31 by the first-in, first-out method.

If the inventory of a particular model comprises one entire purchase plus a portion of another purchase acquired at a different unit cost, use a separate line for each purchase. If units are in inventory at two different costs, enter the units PURCHASED MOST RECENTLY first.

2. Determine the cost of the inventory on December 31 by the last-in, first-out method.

If the inventory of a particular model comprises one entire purchase plus a portion of another purchase acquired at a different unit cost, use a separate line for each purchase. If units are in inventory at two different costs, enter the OLDEST units first.

3. Determine the cost of the inventory on December 31 by the weighted average cost method.

4. would be preferred for income tax purposes in periods of rising prices.

Write a pro-active password checker that checks to make sure that a user entered password meets certain requirements. You must implement a simple program that prompts the user for two String values, a password and the same password again for confirmation. For the purposes of this lab, a legal password must have all of the following properties:

▪ Length of at least 8 characters

▪ Starts with a lower case letter

▪ Ends with a numerical digit

▪ Has one Uppercase

▪ Is exactly equal to the repetition of the password typed for confirmation

Complete your program to prompt the user to enter a password and a confirmation as explained above. If the password is shorter than 8 characters, print Password is too short! Otherwise, if the password does not start with a lower case letter, print Password must start with a lower case letter! Otherwise, if the password does not end with a digit, print Password must end with a digit! Otherwise, if the password does not match the confirmation, print Passwords do not match! If there is no Uppercase letter in the password print Password must contain uppercase letter! Finally, if all the conditions are satisfied, print Password is valid!

A broker has decided to to build a portfolio of two stocks for a retired individual. The first stock "G" has an expected return of 10.25% with a variance of 73.96. The second stock "K" has an expected return of 7.75% with a variance of 18.49. The correlation between the two stocks is -0.58.

a) With the given information, what is the covariance between the two stocks, to two decimal places?

b) With the given information, what is the variance, to two decimal places, of a portfolio of the two stocks where seven times as much is invested in stock K compared to how much is invested in stock G?

c)  With the given information, what is the standard deviation, to two decimal places, of a portfolio of the two stocks where seven times as much is invested in stock K compared to how much is invested in stock G?

d) With the given information, what is the expected return, to two decimal places, of a portfolio of the two stocks where seven times as much is invested in stock K compared to how much is invested in stock G?

What is the amount of the business combination reserve (also known as revaluation surplus)?

Select one:

a. 20    CR

b. 0

c. 7    DR

d. 13    DR

e. 10    CR

f. 10 DR

g. 14    CR

Hi can you do me this 3 exercises? if you answer them all and are correct I will put thumbs up! thanks :)

7) Focus groups of 14 people are randomly selected to discuss products of the Famous Company. It is determined that the mean number (per group) who recognize the Famous brand name is 9, and the standard deviation is 0.79. Would it be unusual to randomly select 14 people and find that greater than 13 recognize the Famous brand name?

8) Assume that there is a 0.05 probability that a sports playoff series will last four games, a 0.45 probability that it will last five games, a 0.45 probability that it will last six games, and a 0.05 probability that it will last seven games. Is it unusual for a team to win a series in 4 games?

9) In a survey of 300 college graduates, 53% reported that they entered a profession closely related to their college major. If 9 of those survey subjects are randomly selected without replacement for a follow-up survey, what is the probability that 3 of them entered a profession closely related to their college major? In a sample of 9 persons, would it be unusual to for 8 persons sampled to have entered a profession closely related to their college major?

An outlet store is having a sale in their Cabin brand sweaters. There are two different pricing systems depending on if it is a Cabin brand or not. Tax must be added on after the sweater charge is computed.
You must have two classes using separate files.

Requirements for Sweater Class
Fields
1. sweater price (in dollars)
2. Boolean to indicate if it is a Cabin brand or not
3. number of sweaters purchased
Methods
1.   One 3 parameter constructor- the constructor uses three parameters representing the sweater price, whether it is a Cabin Brand or not, and the number of sweaters purchased.
2.   Getter and setter for each field
3.   getTotalPurchase method
This method must call the appropriate getter member methods where necessary. Do not access the fields directly.
This method calculates and returns the total amount of the sweater.
If the sweater is Cabin brand, calculate the discount as follows;
-If the customer purchases 1 sweater the discount is 20% of the sweaters price.
-if the customer purchases 2 or more sweaters the discount is 30%
-the customer cannot purchase less than 1 sweater.
-compute the purchase subtotal by subtracting the appropriate discount from the sweaters price.
Use a tax rate of 7% of the purchase subtotal to compute the sales tax in dollars. Add the sales tax amount to the purchase subtotal to determine the total purchase amount.
Return the total purchase amount to the calling code.

Requirements for the SweaterDriver Class
Main method
1.   customer must be prompted appropriately
2.   All values related to money may include values after the decimal point. All values displayed to the screen must display with 2 places after the decimal.
3.   The customer must indicate whether the sweater is Cabin brand or not by typing a single character (y for yes, n for no) program must accept Upper and lower case, Y,y,N,n.
4.   If the sweater is Cabin brand, prompt the customer to enter the number of Cabin sweaters being purchased.
5.   Instantiate a Sweater object using a three parameter constructor.
Note that the parameter that indicates if the sweater is a Cabin brand is a Boolean data type.
The customer must type a single character. You will have to use selection to instantiate a Sweater object with the correct data type foe this parameter.
6.   Display the values in the output by calling the appropriate method of the Sweater object. The output must line up at the decimal point as in the sample runs.
Sample runs
1
Enter the price of the sweater: $50.00
Is the swear a Cabin(Y/N)? N

Price of sweater $50.00
Total purchase $53.50

Run 2
Enter the price of the sweater: $60.00
Is the sweater a Cabin(Y/N)? Y
Enter the number of sweaters being purchased: 2
Price of sweater $60.00
Total Purchase $89.88

Run 3

Enter price of sweater: $40.00
Is the sweater a Cabin(Y/N)? Y
Enter the number of sweaters being purchased: 1
Price of sweater $40.00
Total purchase $34.24

Waterways is considering the replacement of an antiquated machine that has been slowing down production because of breakdowns and added maintenance. The operations manager estimates that this machine still has 2 more years of possible use. The machine produces an average of 50 units per day at a cost of $6.10 per unit, whereas other similar machines are producing twice that much. The units sell for $8.80. Sales are equal to production on these units, and production runs for 260 days each year. The replacement machine would cost $73,000 and have a 2-year life.

Given the information above, what are the consequences of Waterways replacing the machine that is slowing down production because of breakdowns?

An educational psychologist has developed a mediation technique to reduce anxiety. The psychologist selected a sample of high anxiety students that are asked to do the mediation at two therapy sessions a week apart. The participants' anxiety is measured the week before the first session and at each subsequent session. Below are the anxiety scores for the participants. What can the psychologist conclude with α= 0.05?

a) What is the appropriate test statistic?
---Select--- na one-way ANOVA within-subjects ANOVA two-way ANOVA

b) Compute the appropriate test statistic(s) to make a decision about H₀.
critical value =  ; test statistic =  
Decision:  ---Select--- Reject H0 Fail to reject H0

c) Compute the corresponding effect size(s) and indicate magnitude(s).
η² =  ;  ---Select--- na trivial effect small effect medium effect large effect

d) Make an interpretation based on the results.

At least one of the sessions differ on anxiety.None of the sessions differ on anxiety.    

Ruby lives in the community. She is very independent at 89. Ruby has had a hip replacement, and has difficulties walking long distances, but she prefers to walk when she can. She is about a ten minute walk from the shops and often walks into town for a coffee, or to buy her groceries.

Walking home one day, Ruby trips on a broken paver and falls. She cannot get up. A neighbour runs to help and calls an ambulance. Ruby spends four nights in the hospital. She wants to go home, but the health professionals want to make sure Ruby is stable and safe before any decisions are made

1.You are providing support services to Ruby and have identified with her that her goal is to continue living independently in the community. When planning service delivery, what types of resources would you look at in order to deliver identified services that will allow her to do this?

2.Explain three ways in which you would support Ruby to access and negotiate resources

3.What are two actions that should be taken if one of the services Ruby requires is no longer able to provide the level of support required?

4. How could you ensure that the action you take to minimise disruption to service delivery if a service is no longer able to provide the level of support Ruby requires? Identify two methods you would use.

5.Who could you consult when making decisions about Ruby’s new service delivery plan? approx 25 words

6.
