Starting from rest, a basketball rolls from the top to the bottom of a hill, reaching a translational speed of 7.7 m/s. Ignore frictional losses. (a) What is the height of the hill? (b) Released from rest at the same height, a can of frozen juice rolls to the bottom of the same hill. What is the translational speed of the frozen juice can when it reaches the bottom?

Ray Company provided the following excerpts from its Production Department’s flexible budget performance report. (Round "rate per hour" answers to 2 decimal places. Indicate the effect of each variance by selecting "F" for favorable, "U" for unfavorable, and "None" for no effect (i.e., zero variance). Input all amounts as positive values.)

Give an examples of Altruism on a macro level, and micro level, and how the concept would be used to understand an issue involving a large group (macro level) and small group (micro level).

QUESTION

In process improvement efforts, quality costs or cost of quality is a means to quantify the total cost of quality-related efforts and deficiencies. An audit of a firm has revealed that the costs attributed to poor quality have risen sharply from a previous audit, Given that you are to provide advisory services to this firm:

A. Critical enumerate the reasons for accounting for the high costs of poor quality

B. Provide a comprehensive roadmap for the firm to significantly reduce their costs of poor quality and maintain a competitive edge

Lightning is a great illustration from nature of the stunning application of statics and electric fields. There are over 15 different types of lightning. Do a bit of research and select a lightning type that you find interesting. Try to use a different example than those given by your classmates. Address the following discussion item

• What do you find interesting about the type of lighting you selected?
• Describe your lightning type.
• Include a photo, video, or illustration.
• Give a scientific explanation of how your lighting type occurs. Include how charging (or charge separation) occurs..
• What role does induction play?
• Do you think it's feasible to harness the power of lightning? Why or why not. Provide facts to support your position.
• Besides statics and electric fields, give one more example of a physics principle illustrated by lightning.

Example:

We are looking at the cholesterol levels of population of 200 healthy individuals. Cholesterol of the most of individuals is between 190-210mg/dl, with a mean (μ) 200mg/dl and SD (s) 10mg/dl. A study in 10 individuals drawn from same population with cholesterol levels of 180, 200, 190, 180, 220, 190, 230, 190, 190, 180mg/dl gives X̄ = 195 mg/dl and SD (s) = 17.1 mg/dl.

Using the example above solve:

Assign your numbers for mean μ and standard deviation σ.
Then select a number "A" below mean μ, and a number "B" above mean μ.
Use Appendix Table for the Normal Distribution to find the probability
that x is between A and B: P (A < x < B).

Here are steps to follow: convert A to z score (let's call it za),
convert B to z score (let's call it ZB).;
From the Appendix, table find the area under the curve to the left of za and to the left of ZB.
That will give you P (z < za) and P (z < zb).
If za or zb is not in the table, change your A or B.
Use formula: P (A < x < B) = P (za < z < zb) = P (z < zb) - P (z < za)

In an experiment on the Reaction of Magnesium with Hydrochloric Acid.  

What would be the effect of liters of hydrogen produced if:

sort_employees(Employee emps[], int size) (40 pts)
This function should sort the input array based on each employee’s years_of_service. You are required to adapt the Selection Sort code presented in Chapter 6 for the implementation of this function. You can find the original code of the Selection Sort on slide 51 of the chapter.

This is the Selection Sort talked about on the slide of 51. I am not sure where to even begin with this question.

for (int unsorted = 0; unsorted < size - 1; unsorted++)​

{  ​

   // Find the position of the minimum​

   int min_pos = unsorted; ​

   for (int i = unsorted + 1; i < size; i++)​

   {​

      if (values[i] < values[min_pos]) { min_pos = i; }​

   }​

   // Swap the minimum into the sorted area​

   if (min_pos != unsorted)​

   {​

      double temp = values[min_pos];​

      values[min_pos] = values[unsorted];​

      values[unsorted] = temp;​

   }​

}

Write the program in JAVA.

Make an undirected, but disconnected graph of at least 15 vertices and 25 edges.

you may add function calls in your main to add edges between vertices - one function call per edge. You may choose any graph representation of your choice from the 3 ways we discussed in the class.

Write a program to do DFS traversal of the graph.

Also write a program to do BFS traversal of the same graph.

Draw your graph on a paper and upload it with you code.

run the each of the two programs and capture screen shots and submit them. Check that the program does indeed do the correct traversal (based on your hand drawn graph)

1. In reviewing firm liquidity situations, lenders often count on the Quick Ratio (or Acid-Test ratio). Why is this ratio important if the firm has an adequate Current Ratio?
2. Which of the following ratios is most important when reviewing a firm’s financial health from its day-to-day operations – Gross margin, Operating margin, and Net profit margin?
3. (a) A firm has an Equity Multiplier (EM) equal to 6.67. What is the firm’s Debt Ratio (DR)? (b) If the industry average DR is 0.79, is this firm’s debt situation Better, Worse, or Uncertain compared to the industry as a whole?

code a Java program that:

Requests from the user for a text filename to read the text inside, then it calculates the frequency of each letter contained in the file. When punctuation is ignored, there is no need to distinguish between upper and lower case. The text file should be named as “input” with only letters inside. For example,

a 11

c 9

e 16

Discuss how the ARIES algorithm must operate under the circumstances that the system crashes during recovery
