Mercury is a persistent and dispersive environmental contaminant found in many ecosystems around the world. When released as an industrial by-product, it often finds its way into aquatic systems where it can have deleterious effects on various avian and aquatic species. The accompanying data on blood mercury concentration (µg/g) for adult females near contaminated rivers in a state was read from a graph in an article.

Determine the value of the 10% trimmed mean. (Round your answer to three decimal places.)

In your internet browser, search for the term "Budgetary Slack." Review a few of the results so you understand what it is and when it is used by managers. Then, read the "Ethics Challenge" near the end of the Master Budgeting chapter problems in your textbook.  

Required:

Share your responses to the following questions with your classmates. Based on your reading:

1. Do you think Granger Stokes is using budgets appropriately?
2. What sort of behavioral consequences may occur as a result of the way budgets are used at Prime Drive?
3. What would you do if you were in Keri Kalani's position?  

As a clinic manager, you have been watching carefully as a strong hurricane has formed in the Gulf of Mexico, and is expected to make landfall near Corpus Christi in 2 days. This is a very large and intense storm, and is expected to cause widespread flooding and wind damage, as well as power outages. What types of things are you thinking about concerning strategic planning, and risk and crisis management? Several members of your staff are requesting to leave now to help take care of their family members who live hear Corpus Christi. What type of strategic LEADERSHIP planning and risk management would you think about?

1. As an Geotechnical Engineer for a company you have been instructed to handle a project to develop a new Mall. The project currently in construction stage. During process of pile installation, the contractor notices few problems with the site condition:

1. Limited area for work space which might have problem to use conversional method for pile installation.
2. Project site is near with Hospital (contractor must control the sound pollution).

As a consultant you are need to solve these problems and need to suggest (with explanation) suitable method to install the pile.

2. After complete installation of pile, you are need to suggest method/s to conduct pile test (with explanation).

In the Little Albert experiment, Watson taught a young child to associate the sight of a white rat with fear. He did this by giving the child a rat, then making a very loud sound near him, which elicited a fear response. Eventually, the sight of any white, fuzzy object (including a coat, a rabbit, and a Santa mask) elicited an immediate fear response (Cherry & Morin, 2019). Do you think this experiment by Watson was ethical? He created a lifelong fear in the child for the purposes of research. If you were going to repeat his experiment, what would you do differently to make it more ethical by today's standards?

Problem 26.49: Resolution of the eye, I.

Even if the lenses of our eyes functioned perfectly, our vision would still be limited due to diffraction of light at the pupil.

Part A

Using Rayleigh's criterion, what is the smallest object a person can see clearly at his near point of 22.5 cm with a pupil 2.25 mm in diameter and light of wavelength 498 nm ? (To get a reasonable estimate without having to go through complicated calculations, we'll ignore the effect of the fluid in the eye.)

Part B

Based upon your answer, does it seem that diffraction plays a significant role in limiting our visual acuity?

25. A turbojet engine gets most of its thrust from an airflow that bypasses the combustor and turbine sections.   a. True b. False


26. A turboprop engine gets most of its thrust from an airflow that bypasses the combustor and turbine sections. a. True b. False

27. In a gas turbine engine for aircraft applications, a diffuser is needed at the inlet to … a. Reduce the speed of the air entering the compressor section to near zero relative to the compressor air intake. b. Reduce the pressure of the air entering the compressor. c. Increase the temperature of the air entering the compressor.   d. Reduce heat transfer from the air to the surroundings, as this heat will be of value in the engine.

Answer question 2!!

1. a boat is bobbing up and down on the water as waves pass underneath it. The depth of the water under the boat oscillates between 3 m and 4 m. The boat is stationary with respect to the shore and it is 2.9s between the crests of successive waves. A person on shore sees the crests of the wave passing by at 2 m/s. what is the distance between crests of this wave?

2. Two ducks are floating close together on the water near the boat in problem 1. When the first duck is on the peak of a passing wave the second duck is 30 cm below it and moving upwards. How far apart are the ducks?

Excel and Writing Case Assignment Description: ABC Corporation has a machine that requires repairs or should be replaced. ABC has evaluated the two options and calculated the cash flows resulting from each option as follows:

Option A: Repair the Machine

Year Cash Flow

0 -50,000

1 15,500

2 20,100

3 18,900

4 17,100

5 13,700

Year Cash Flow

Option B: Buy a new Machine

Cash Flow

0 -400,000

1 51,300

2 155,000

3 127,800

4 126,900

5 125,100

You have recently been hired by ABC Corporation and your first assignment is to help them decide which of these two options should be pursued. You would like to apply Capital Budgeting and Time Value of Money concepts you have learnt to analyze the problem and present your recommendation to your boss, Ms. Jane Austen. Conduct the analysis by calculating the following: Payback Period Net Present Value (NPV) Internal Rate of Return (IRR) Modified Internal Rate of Return MIRR Profitability Index (PI) Calculate and graph the NPV profile for both options Calculate cross-over rate if there is one The company has a Weighted Average Cost of Capital (WACC) of 8%.

For this analysis, your boss asked you to conduct a sensitivity analysis by calculating NPV at three different discount rates: 8% (the current WACC), 10% and 14%. You must use the built-in financial functions and logical functions in Excel spreadsheet. The spreadsheet should be a model such that if the cash-flows are changed, the answer and recommendation should change automatically in the spreadsheet.

You must pay special attention to calculating Payback and Discounted Payback measures and it should change as inputs are changed. Please use =IF() function to display your decision. Your Excel must also have a properly labeled graph for NPV Profile for two projects.

Please post with excel solutions - Edit: Make an excel spread sheet showing the function / calculations with formula so they automatically calculate.
