What are the different stages of the Lewis two-sector model?

Bullock Gold Mining Seth Bullock, the owner of Bullock Gold Mining, is evaluating a new gold mine in South Dakota. Dan Dority, the company’s geologist, has just finished his analysis of the mine site. He has estimated that the mine would be productive for eight years, after which the gold would be completely mined. Dan has taken an estimate of the gold deposits to Alma Garrett, the company’s financial officer. Alma has been asked by Seth to perform an analysis of the new mine and present her recommendation on whether the company should open the new mine. Year Cash Flow 0 −$625,000,000 1 70,000,000 2 129,000,000 3 183,000,000 4 235,000,000 5 210,000,000 6 164,000,000 7 108,000,000 8 86,000,000 9 − 90,000,000 Alma has used the estimates provided by Dan to determine the revenues that could be expected from the mine. She also has projected the expense of opening the mine and the annual operating expenses. If the company opens the mine, it will cost $625 million today, and it will have a cash outflow of $90 million nine years from today in costs associated with closing the mine and reclaiming the area surrounding it. The expected cash flows each year from the mine are shown in the nearby table. Bullock Gold Mining has a 12 percent required return on all of its gold mines. QUESTIONS Construct a spreadsheet to calculate the payback period, internal rate of return, modified internal rate of return, and net present value of the proposed mine. Based on your analysis, should the company open the mine? Bonus question: Most spreadsheets do not have a built-in formula to calculate the payback period. Write a VBA script that calculates the payback period for a project.

Consider the following function:

int counter( int n)

{ int s = 0;

   for ( int i = 0; i < n; i++)

            for ( int j = i; j > 0; j--)

                       s = s + 1;

  return s;

}

Part (a): How many times "s=s+1;" will be executed? Determine a precise count.  Show all your work.

Part (b): What is the time complexity of the "counter" function in terms of Big-O notation? Justify and show all your work.

How to write a Java program that has a base class with methods and attributes, subclasses with methods and attributes. Please use any example you'd like.

Jessica purchased a home on January 1, 2018 for $580,000 by making a down payment of $230,000 and financing the remaining $350,000 with a 30-year loan, secured by the residence, at 6 percent. During 2018 and 2019, Jessica made interest-only payments on this loan of $21,000 (each year). On July 1, 2018, when her home was worth $580,000 Jessica borrowed an additional $145,000 secured by the home at an interest rate of 8 percent. During 2018, she made interest-only payments on the second loan in the amount of $5,800. During 2019, she made interest only on the second loan in the amount of $11,600. What is the maximum amount of the $32,600 interest expense Jessica paid during 2019 may she deduct as an itemized deduction if she used the proceeds of the second loan to finish the basement in her home and landscape her yard? (Assume not married filing separately.)

$0. $11,600. $30,682. $7,200. $32,600.

Daily demand is normally distributed with mean 22 units and SD=6. Ordering cost is $21/order, carrying cost is $2.5 per unit per year. The item is used 365 days a year. Order lead time is 4 days. The order point should have a 99% target service level.

Find:

-avg inventory level

-avg number of orders/yr

-avg number of stockouts/yr

-avg time (years) between stockouts

Policy I is the (Q,R) policy determined above.

Policy II: Increase the order quantity by 10 units, and re-evaluate the policy using the original order point from policy I

Policy III: Increase the order point by 5 units, and re-evaluate the policy using the original order quantity from Policy I.

Both policies II and III should have the same total average inventory (cycle stock and safety stock). However, the mix of cycle stock vs. safety stock varies between the two.

Use recursion tree to solve the recurrence:

T(n) = T(n/15) + T(n/10) + 2T(n/6) + n^(1/2)

1. What do you think is the purpose of humans having microexpressions?

2. Given what you know about biological psychology, what might be the source of microexpressions?

3. Are these microexpressions useful to us in any way? If yes, how?

4. How do microexpressions reveal a person's motivation? Give a real-world example. How might a person working in a given profession use the skill of reading microexpressions? Again, give a real-world example.

1. Many employees are unwilling to relocate geographically because they like their current community and their spouses and children prefer not to move. Yet employees need to develop new skills, strengthen skill weaknesses, and be exposed to new aspects of the business to prepare for management positions. How could an employee’s current job be changed to develop management skills without having to relocate them?

2. What is coaching? Is there only one type of coaching? Explain.

Lucy has just been promoted to a managerial position and given a new office. She is very fond of small Persian carpets and Native American paintings. Her utility function for carpets(x) and paintings (y) is given by: U = 100 * sqrt(xy)

Her company gave her a budget of $7,200. Persian carpets cost $700 each and Native painting costs $500. Using Excel spreadsheet, develop columns for quantity and of carpets and paintings within her budget. Use 0,1,2,....10 carpets as possible quantities. Develop columns of TU, MU, and MU/$ for carpets and paintings and answer the following questions.

At the maximum total utility level, what is the optimal number of carpets she gets and what is the optimal number of paintings she gets?
