take the role of mentor to a new project manager within your organization. This assignment focuses on guidance the mentor provides the new project manager regarding cost.

Cost serves several purposes for an organization: (1) planning and budgeting, (2) assisting in decision making, (3) comparing actual to budget (control), and (4) calculating income generated from operations and projects (score-keeping). Select one these areas and prepare a short document outlining the following items:

• Identify one of the cost purposes listed above.
• Select two of the five cost classifications described in the text: financial statement presentation (cost function): cost behavior, assigning costs to products and services, costs for decision making, and cost of quality (see page 75).
• Describe how knowledge of cost, as described within its classification, is needed to effectively manage costs and improve the success of a project for the stated purpose.

cA Christmas tree provider sells trees on Dec. 20th. They sell trees for 5 full days, closing the lot at the end of the day on December 24th. Based on past sales data, they decided to cut down 220 trees for this year's selling season. Each cut tree has a 70% chance of being a healthy tree that a customer would purchase and a 30% chance of being an unhealthy tree that nobody wants to purchase. On each of the 5 selling days, the number of customers who show up prepared to purchase a tree is normally distributed with an average of 30 and a standard deviation of 5.

a) On average, How many healthy trees do they have?

b) What is the likelihood they end up with 168 or more healthy trees?

c) What is the likelihood that 168 customers or more visit to purchase a tree?

d) What is the likelihood that more customers visit over the 5 days than they can provide healthy trees for? (stockout)

e) How many trees do they need to cut down to ensure stocking out is less than or equal to 10%?

f) Suppose it costs $25 for each tree they cut down and healthy trees are sold for $100. Is it better to stick with the 220 tree strategy or change it to what you found in part e?

Question 2:

Write a Java console application that will allow a user to add contacts to a contact list and view their current contact list sorted alphabetically. Your program should prompt the user to select an action (add or view). If the user chooses to add a contact, the contact information should be entered using the following format: Firstname Lastname, PhoneNumber If the user chooses to view their contact list, your program should display each contact on a separate line using the following format: Firstname Lastname: PhoneNumber Assume that both contact names and phone numbers will be unique (no two contacts can have the same name or phone number. A contact can only have one phone number, and a phone number can only belong to one contact). Create the appropriate objects based on the application description. Select the most suitable data structure(s) for this application.

(Global Positioning System) and GIS (Geographic Information Systems) both utilize location- based services. What are location- based services and what are some of the exciting new applications of LBS in your opinion? Give an example of how you personally have used related services.

InPython,

Create a list of strings, don’t ask from the user, and return a list with the strings in sorted order, except group all the strings that begin with 'x' first.

e.g. ['mix', 'xyz', 'apple', 'xanadu', 'aardvark'] yields

['xanadu', 'xyz', 'aardvark', 'apple', 'mix']

# Hint: this can be done by making 2 lists and sorting each of them before combining them.

(a) How many grams of CaCl2 are needed to make 250.9 g of a solution that is 30.5% (m/m) calcium chloride in water? Note that mass is not technically the same thing as weight, but (m/m) has the same meaning as (w/w).

-How many grams of water are needed to make this solution?

(b) What is the volume percent % (v/v) of an alcohol solution made by dissolving 117 mL of isopropyl alcohol in 747 mL of water? (Assume that volumes are additive.)

(c) The mass of solute per 100 mL of solution is abbreviated as % (m/v). (The abbreviation % (w/v) is also common.) How many grams of sucrose are needed to make 735 mL of a 34.0% (w/v) sucrose solution?

In the television show “The Six Million Dollar Man”, Colonel Austin had superhuman powers. In one episode, he tries to catch a man fleeing in a sports car. We’ll assume in this problem that the distance between them at t=0 is 100 m. The car starts at rest. At t = 0.0 s, the driver notices Colonel Austin. From then on, the car accelerates at 5.0 m s -2 , away from Austin. Sweet, but a bit slow on the uptake, Colonel Austin remains motionless until t = 2.0 s, at which point he begins his pursuit, at a constant speed of 50 m/s. a) How far ahead is the car when Colonel Austin begins to move? b) At what time (t>0) is Austin furthest ahead of the car? And what is that separation? c) At what time(s) does Austin catch the car? d) What is the critical initial separation (all other parameters remaining the same) beyond which Colonel Austin will never catch the car?

Today’s price of Delta is $150 per share. You are neither bullish nor bearish about Delta, but you believe that the share price will not move by a lot in the near future. To implement your view, you decide to sell a straddle with one month until maturity. An option dealer provides you quotes on one-month Delta options. For a call option with a strike of $150, the dealer quotes you a price of $4.32. For a put option with a strike of $150, the dealer quotes you a price of $4.32. The c.c. risk-free rate is zero. What is the profit to the short straddle if Delta trades at $200 per share in one month?

There are 2 breakevens, what is the high and what is the low? (There should be two answers, one for high and one for low)

Go to the Phase Changes tab. Select the particular molecule, and set the temperature to the given values by using the stove to increase or decrease the temperature. Increase the pressure of the cylinder by moving the lid of the cylinder down with the help of the finger. The pressure of the cylinder is indicated by the pressure gauge on the top left corner of the simulation. On the right-hand side of the simulation is the phase diagram for the molecule.

As the molecules collide on the walls of the cylinder, the pressure of the cylinder does not remain constant; it fluctuates slightly as indicated by the gauge.

In the phase diagram, observe the red point. When a particular molecule is selected, set the temperature and pressure condition to the required value. Observe the position of the red point on the phase diagram when the pressure reaches approximately near the required value.
