Are you a university or school looking for an online tutoring partnership ?

s ago. The reduced book value now stands at $60,000. A new model of the machine is currently available for $139,350. The new machine has a useful life of five years, at which time it will be sold for $20,000. Using the new machine, the expected unit sales of the car jacks would be 6,000 car jacks per annum. The estimated unit selling price is $35 for the first year. As a result of the COVID-19 pandemic in Singapore, JJ is experiencing labour shortage. JJ will have to transfer workers from another department to the new project. These workers earn a contribution of $2 per direct labour hour in their original department. The fixed overhead cost would be $2.20 per hour and this is expected to remain unchanged. JJ’s products are being sold to a distributor. The sales agreement allows the selling price to rise at the rate of 10 percent per year after the first year. The unit cost price, except for fixed costs, is expected to increase at the same rate as the selling price. Working capital requirements are expected to be $15,000 in the first and second years, increasing to $18,000 in the third year and is expected to remain at this level till the end of the project. All the amounts of working capital will be recovered at the time of project termination. The new project uses cutting-edge technology and so enjoys a tax holiday from the authorities. The drawback of using this high-risk approach is that the new project requires a minimum return of 27 percent per annum. Required: Identify the relevant cash flows for the decision as to whether JJ should proceed to purchase the new machine. Note: To show all workings with accompanying explanations. Word count requirement: 800

8.Hi, i have a task where i need to calculate the 3 months weighted moving average for May 2021, The ...

eight should be based on the count of sales for the previous period, the actual period and the next period.
In the excel you can see the housing data:
period(month)
sum of prices(K)
sum of the asses value(T)
K/T value (sum of prices/sum of the asses value)
The answer i'm looking for is that for May 2021 the price development in percentage should be 9.5% compared to three month back. To calculate the price development you just divide the K/T value, for example:
period 1 K/T value = 1.4
period 4 K/T value = 1.9
Price development = (1.9/1.4)-1 = 35.7% increase.
So i want to see 9.5% increase on May 2021 compared to 3 months earlier.

a one million square foot warehouse that they have recently developed. In typical Wal-Mart fashion, they have given you a “take it, or leave it” final offer. The terms are:
Purchase Price: $165 million
Facility Size 1,000,000 SF
Lease Term 7 years
Rent $7 PSF NNN
Operating Expenses Wal-Mart (tenant) pays all operating expenses, utilities, and property taxes (owner pays none)
Renewal Options 7-year extension at $8 per ft2; a second 7 year extension at $9.50 per ft 2; a third 7 year extension at $11.50 per ft.2. All at Wal-Mart’s choice (i.e. it’s Wal-Mart’s option). Wal-Mart pays all operating expenses, utilities, property taxes, and capital expenditures undertaken during all lease renewal periods.
You know the market and feel that the location is good, and that the warehouse market is in good supply/demand balance. Vacancy rates are 4% - 5% in quality facilities, while net rents in the market are running about $7.50 - $8 PSF (i.e. a slight premium to the Wal-Mart lease). You have recently seen comparable sales that have traded in the range of $160 - $200 PSF. You also know that implied discount rates are currently at about a 3% premium to implied cap rates and capital costs are running at $0.50 PSF per annum.
You know from your Real Estate Finance & Investments classes that you can value a building using a direct capitalization approach, a comps analysis and a DCF analysis. You also have a handy template that you’ve been using for these analyses which you will need to complete in order to come to a view on value.
It’s decision time…would you agree to pay the $165 million that Wal-Mart is asking? Why or why not?

b) Calculate the final mass of the anhydrous cobalt (II) chloride remaining in the cruiio8icible. [T1]
c) Calculate the mass of water given off by the sample of hydrated cobalt (II) chloride. [T1]
Moles of Products:
a) Calculate the moles of anhydrous cobalt (II) chloride remaining in the crucible. [T1]
b) Calculate the moles of water released from the hydrate. {T1]
4. Mole Ratio
a) Create an experimental mole ratio between the b) and a). [T1]
5. Formula of Hydrate: State the chemical formula you have determined for this hydrate.
Round the formula to the closest whole number value for x. [T1]
Discussion/Conclusion Questions: [T6]
Based on the chemical formula of the hydrate, calculate the percentage composition (percent by mass) of the hydrated cobalt (II) chloride. Remember to determine the percentage of each element (Co, Cl, H, and O). [T2]
A possible source of systematic error in this experiment is insufficient heating. Suppose that the hydrate was not completely converted to the anhydrous form. Describe how this would affect: the calculated percent by mass of water and the experimental molecular formula (i.e. would x be higher, lower or the same).
Suppose a student spilled some of the hydrated cobalt (II) chloride. Describe how this would affect the calculated percent by mass of water (would it be higher, lower or the same) and the experimental chemical formula of the hydrate. [T2]

Needless to say, this sales strategy will be effective when the distribution channels for the product in question are well planned, when there is sufficient advertising to let the consumers know about the promotion, when the package clearly indicates the coupon redemption scheme with the expiration date, if any, and the packaging of the product is of the right size (neither too big nor too small to serve the needs of the consumer). Of course, all these factors will not help, unless there is an established frequent need for the product for consumers.
Develop a theoretical framework for the above mentioned scenario.

Ques. 14
Read the following information identify the concepts and develop a conceptual model for the scenario below.
Incidence of smoking in movies has started to increase again, after having declined for several decades. According to the National Cancer Institute smoking is seen in at least three out of four contemporary box office hits. What's more, identifiable cigarette brands appeared in about one-third of all movies in 2019. Exposure to smoking in movies is an important predictor of adolescent smoking initiation: smoking in movies has been shown to affect adolescents' intentions to start smoking. In turn, the intentions to start smoking are determined by a more positive attitude toward smoking after seeing a film character smoke. Recent research has revealed that the relationship between seeing a film character smoke and the attitude toward smoking is stronger when a person's identification with a film character increases. These findings are consistent with social learning theory, which predicts that attitudes and behaviors are modeled by observing the behaviors of others.

1)Dorothy Dunning , Chief Production Manager , was on top of the world just two years ago . In her nontraditional job , she was cited to be the real backbone of the company , and her performance was in no small measure responsible for the mergers the institution was contemplating with other well - known global corporations . Of late though , the products of the company had to be recalled several times owing to safety concerns . Quality glitches and production delays also plagued the company . To project a good image to consumers , Dunning developed a very reassuring web site and made sweeping changes in the manufacturing processes to enhance the quality of the product , minimize defects , and enhance the efficiency of the workers , A year after all these changes , the company continues to recall defective products !

on a subsample of weekly data from Randall’s Supermarket, one of the biggest in the UK. Randall’s marketing management team wishes to identify trends and patterns in a sample of weekly data collected for a number of their loyalty cardholders during a 26-week period. The data includes information on the customers’ gender, age, shopping frequency per week and shopping basket price. Randall’s operates two different types of stores (convenient stores and superstores) but they also sell to customers via an online shopping platform. The collected data are from all three different types of stores. Finally, the data provides information on the consistency of the customer’s shopping basket regarding the type of products purchased. These can vary from value products, to brand as well as the supermarket’s own high-quality product series Randall’s Top. As a business analyst you are required to analyse those data, make any necessary modifications in order to determine whether for any single customer it is possible to predict the value of their shopping basket.
Randall’s marketing management team is only interested in identifying whether the spending of the potential customer will fall in one of three possible groups including:
• Low spender (shopping basket value of £25 or less)
• Medium Spender (shopping basket value between £25.01 and £70) and
• High spenders (shopping basket greater than £70)
For the purpose of your analysis you are provided with the data set Randall’s.xls. You have to decide, which method is appropriate to apply for the problem under consideration and undertake the necessary analysis. Once you have completed this analysis, write a report for the Randall’s marketing management team summarising your findings but also describing all necessary steps undertaken in the analysis. The manager is a competent business analyst himself/herself so the report can include technical terms, although you should not exceed five pages. Screenshots and supporting materials can be included in the appendix.
Requirements
After completing your analysis, you should submit a report that consists of two parts. Part A being a non-technical summary of your findings and Part B a detailed report of the analysis undertaken with more details.
Part A: A short report for the Head of Randall’s Marketing Management (20 per cent). This should briefly explain the aim of the project, a clear summary and justification of the methods considered as well as an overview of the results.
Although, the Head of Randall’s Marketing Management team who will receive this summary is a competent business analytics practitioner, the majority of the other team members have little knowledge of statistical modelling and want to know nothing about the technical and statistical underpinning of the techniques used in this analysis. This report should be no more than two sides of A4 including graphs, tables, etc. In this report you should include all the objectives of this analysis, summary of data and results as well as your recommendations (if any).
Part B: A technical report on the various stages of the analysis (80 per cent).
The analysis should be carried out using the range of analytics tools discussed:
• SPSS Statistics
Ensure that the exercise references:
• Binary and multinomial logistic regression
• Linear vs Logistic regression
• Logit Model with odds Ratio
• Co-efficients and Chi Squared
• MLR co-efficients
• Assessing usefulness of MLR model
• Interpreting a model
• Assessing over-all model fit with Psuedo R-Squared measures
• Classification accuracy (Hit Ratio)
• Wald Statistic
• Odd ratio exp(B)
• Ratio of the probability of an event happening vs not happening
• Ratio of the odds after a unit change in the predictor to the original odds
• Assumptions
• Residuals analysis
• Cook’s distance
• DfBeta
• Adequacy (with variance inflation factor VIF and tolerance statistic)
• Outliers and influential points cannot just be removed. We need to check them (typo? – unusual data?)
• Check for multicollinearity
• Parsimony
Write a short and concise report to explain the technical detail of what you have done for each step of the analysis.
The report should also cover the following information:
• Any type of analysis that might be useful and check whether the main assumptions behind the analyses do not hold or cannot be
• Give evidence of the understanding of the statistical tools that you are using. For example, comment on the model selection procedure and the coefficient interpretation, e.g. comment on the interpretation of the logistic regression coefficients if such a method is used and provide an example of
• Conclusions and explanation, in non-technical terms, of the main points

Write the pseudocode needed to complete Chapter 5, number 9 – Pennies for Pay.
Implement Pennies for Pay in Java.
The Secondhand Rose Resale Shop is having a seven-day sale during which the price of any unsold item drops 10 percent each day. Design a class diagram showing the class, the application program, the relationship between the two, and multiplicity. Then write the Java code as described below. Be sure to follow the CSI 117 Style Criteria (Links to an external site.) for naming conventions, class diagrams, pseudocode, keywords, and operators.
An Inventory class that contains:
an item number and the original price of the item. Include the following:
A default constructor that initializes each attribute to some reasonable default value for a non-existent inventory item.
Another constructor method that has a parameter for each data member, called the overloaded constructor. This constructor initializes each attribute to the value provided when an object of this type is instantiated. Be sure to incorporate adequate error checking for all numeric attributes.
Accessor and mutator methods for each attribute. Be sure to incorporate adequate error checking for all numeric attributes.
Extra credit for including Javadoc comments.
An application program that contains two methods: the main() module and the printSaleData()module.
The main()module must do the following:
create an Inventory object using the default constructor
use a loop to get inventory items from the user. The user should enter the item number and the original price of the item. This loop should continue until the user indicates that they have no more items to enter. For each item entered by the user, the code inside the loop should do the following 2 items:
set the attributes of the Inventory object by calling the appropriate method in the Inventory class for each item entered by the user
send the Inventory items, one at a time, to the printSaleData() module for processing
Extra credit for including Javadoc comments.
The printSaleData()module must accept an Inventory object and produce a report that shows the item number and the price of an inventory item on each day of the sale, one through seven, using a loop. For example, an item with an original price of $10.00 costs 10 percent less, or $9.00, on the first day of the sale. On the second day of the sale, the same item is 10 percent less than $9.00, or $8.10.

a tilebased game,
2D rectangle tiles with a size of 5000X5000 pixels per rectangle.
I make every rectangle know the 4 neighbouring rectangles in the map so starting from one you can generate an essentially infinite map.
I want to move this map around instead of moving the player around, the player stays centered on screen and since the map moves under him it looks like he's the one doing the moving.
So I know the following things:
Width and height of a single section:
5000X5000 pixels
the x and y location of the center section can be a value anywhere from -5000,-5000 to 5000,5000
The visible screen real estate is 1920 X 1080 pixels big
0X,0Y always stars top left, bottom right is 5000X5000
What I need to end up with:
A percentage value of howmuch this specific section is visible on screen, "inside the rectangle that is the scfeen)

at her at speed of 40m/s. She shouts, “Youch!’ because the fast-moving ball hurts her hands. She quickly learns how to move her arms and hands along with the ball as she catches it to reduce the magnitude of the impulse force. If the contact time of the collision is increased from the original value of 3.5ms with no arm or hand movement, to 8.5ms in the manner described, how do the magnitudes of the average impulse forces compare? Calculate both of these average forces.

You will use a single backing array(instead of two) and two hash functions (both MultiplicativeHashFunction objects), h1 and h2.
The z values for your hash functions (and all subsequent hash functions needed when resizing or rehashing) will be taken from an array of integers passed to the CuckooHashTable constructor. The first value in the array will be used for the first incarnation of h1, the second value for the first incarnation of h2, the next two values will be used for the next incarnations of h1 and h2, etc.
Note: be careful to follow this. We will be checking your array (via toString()) and correctness will depend on using the same values of z as we do when generating the test code. The MultiplicativeHashFunction objects you will use also have a getParams() method to show the value of z,w,d when that hash function is used.
When adding an item, x, that is not in the hash table already, always add it to t[h1(x)] (even if t[h1(x)] is already taken and t[h2(x)] is available).
The load factor must always satisfy α=n/t.length≤1/2. If adding an item will violate this then resize the table (doubling its size) and rehash everything (before doing the add).
After removing an item, if the load factor satisfies α=n/t.length<1/8 AND the dimension satisfies d≥5 then resize by reducing the size of the bucket table by a factor 2 and rehash everything.
Each time you resize you will create two new hash functions using the next two z values (that were initially passed to the constructor).
Your constructor should initialize an empty bucket array of size 16 (i.e., d=4). This is the minimum size your bucket array should ever be. Never let the dimension be smaller then 4.

onnect a line between every two consecutive points (xi, yi) and (xi+1, yi+1), where 0 <= i <= n.
xi = s * ((a + b) * cos (i * PI) - b * cos ((a + b) / b * i * PI))
yi = s * ((a + b) * sin (i * PI) - b * sin ((a + b) / b * i * PI))
Verify with s = 10, a = 19, b = 5, n = 1000 to get this displayed result.
Note that the sin and cos trigonometry functions accept a radiant value not angle. For example, 30 degree should be replaced with PI/180*30 instead. Moreover, the divisions inside the functions need to be kept in double not int precision in order to render a correct result.

117.Let's say that I have a data set of every time a certain person has coughed since the beginning of ...

his year. I'm looking for a formula that will tell me the probability that a person will cough x number of times in a given week.
I started with the Poisson Distribution, but Poisson doesn't seem to take into account standard deviation. To calculate the probability with Poisson, only the mean, expected value, and test value are needed, meaning the variance/standard deviation of the data could vary widely, and you'd still get the same probability distribution. For example, if someone coughed exactly 5 times everyday, you'd get the same probability distribution if this person alternated coughing 0 times one day, 10 times the next, 0 times the next day, 10 times the next, and so on.
Does my question make sense? Thanks for your help.

s, you run the following re- gression on a sample of 65 countries for the year 2012:
books = 8.2314 + (1.0329)
+ 0.3149 age (0.4111)
8.1391 (0.5812)
?
income
4.8121 (0.3543)
+
ereaders,
3.4125 educ (0.7314)
where books is the number of paperback novels purchased in 2012, income is per capita GDP in 2012, educ is the average number of years of education for the population in 2012, age is the average age of the population in 2012 and ereaders is the number of electronic readers (e.g. Kindles) sold in 2012. The numbers in parentheses refer to standard errors corresponding to the estimated coefficients. You also find that R2 = 0.7231 and SSR = 1, 231.
(a) Which of the slope coefficients are statistically different from zero at the 5% level of significance? Perform statistical tests to answer this question. [8 marks]
Solution: Each test carries 2 marks. t ratios are: 14.0039, 4.66, 0.7659, -13.5819. The 2.5% critical value for a tn?k=65?5=60 distribution can be seen to be 2.0000, implying that all coefficients except the one on age are significant.
(b) Does the intercept have a plausible interpretation? Explain briefly. [4 marks]
Solution: The intercept indicates that demand for paperback novels equals 8.2314 when income, educ, age and ereaders all equal zero. Clearly this is not plausible.
(c) Construct a 95% confidence interval for the coefficient on age. [8 marks]
Solution: CI is given by [bage
