Consider the following processes along with their burst time (in Calculate the average waiting time if the processes arrive in the following order

Calculate the average waiting time if the processes arrive in the following order

(i)P1, P2, P3

(ii)P2, P3, P1

(i) Case 1: Consider a case if processes P1, P2, P3 arrive at the same time say 0 ms in the system in the order P1, P2, P3. The arrival of processes is represented in the Gantt chart as shown below.

Gantt chart

                                          20                                             30                                            35

Therefore, average waiting time =

Turnaround Time =

Case 2: Processes arrive in order P1, P2, P3, let us assume at 0 ms, 2 ms and 4 ms, respectively.

Arrival Time: Time at which the process arrives in the ready queue.

Gantt chart: Draw the Gantt Chart

Waiting time for process P1 = 0 ms

Waiting time for process P2 = 20 ms – 2 ms = 18 ms

Waiting time for process P3 = 30 ms- 4 ms = 26 ms

Calculate the average waiting time

Calculate the Turnaround Time

In a game of basketball, a forward makes a bounce pass to the center. The ball is thrown with an initial speed of 4.9 m/s at an angle of 20 ∘   above the horizontal. It is released 0.80 m above the floor.

What horizontal distance does the ball cover before bouncing?

write the pseudocode to process these tasks:

1. From the random module import randint to roll each die randomly
   1. # in pseudocode, import a random function
   2. # the name is helpful for the next M5-2 assignment
2. Define a class called Dice
   1. In Python, the syntax has a colon after it: class Dice():
   2. In pseudocode, you can specify it generally or be specific
3. Under the class declaration, list the attributes. Here are some tips:
   1. # attributes are what we know about a single die (dice is plural)
   2. # self is the first attribute in Python and must always appear first
   3. # add a num_sides attribute and to set it to 6 for the 6 sides on the dice
4. Define a method for roll(self)
   1. # it describes what happens when we roll a single die
   2. # in the code, it will look like this example
      1. def __init__(self, dice_sides=6):
      2. # in pseudocode, we do not worry about the punctuation
      3. # just list it as part of your logic
5. Under roll(self), return a random int value between 1 and self.dice_sides
6. Save this file as M5Lab1ii - you can save it as MS Word or a text file.

For the second module, write the pseudocode to complete these tasks:

1. In the same M5Lab1ii file, start a second module below the first module.
2. From a new dice module, import our Dice class
3. Create a 6-sided die by using assignment # for example: dice = Dice()
4. Create an empty results list
5. Write a for statement that takes each roll_num in range() and rolls it 100 times
6. Set the value of result to dice.roll()
7. For each roll and append it to the results list using your list’s name and .append() with the variable for each dice roll inside the parameters for append(). For example:
   1. # yourlistname.append(result)
8. Refer to the name of your list within the print() parameter to print the results.
9. 100 dice rolls for the values 1-6 appear in a list on the Python shell.
10. Save the two modules in M5Lab1ii - you can save it as MS Word or a text file.

A project that costs $2,500 to install will provide annual cash flows of $750 for each of the next 5 years.

Sunland Handicrafts, Inc., has net sales of $3.20 million with 50 percent being credit sales. Its cost of goods sold is $1.92 million. The firm’s cash conversion cycle is 51.5 days, and its operating cycle is 86.5 days. What is the firm’s accounts payable?

Sodium trioxalatocobaltate (III) trihydrate is prepared by the following reactions:
[Co(H2O)6Cl2] + K2C2O4 *H2O >>> Co2O4 + 7 H2O

2CoC2O4 + H2O2 + 4 Na2C2O4 >>> 2 Na3[Co (C2O4)3*H2O + 2NaOH

what is the percent yield of Na3[Co (C2O4)3*H2O if 7.6 grams are obtained from 12.5 grams of [Co(H2O)6]Cl2 ? ( assume excess amount of the other reagents.)

Adjustment Letter: Ben & Jerry’s

In an exciting inside look, you see managers discussing six factors that determine Ben & Jerry’s continuing success. Toward the end of the video, you hear staffers discuss a new packaging material made with unbleached paper. As a socially responsible company, Ben & Jerry’s wanted to move away from ice cream packages made from bleached papers. Bleaching requires chlorine, a substance that contains dioxin, which is known to cause cancer, genetic and reproductive defects, and learning disabilities. In producing paper pulp mills using chlorine are also adding to dioxin contamination of waterways. After much research, Ben & Jerry’s found a chlorine-free, unbleached paper board for its packages, That was the good news. The bad news is that the inside of the package is now brown.

Assume you have been hired at Ben & Jerry’s to help answer incoming letters. Although you are fairly new, your boss gives you a letter from an unhappy customer. This customer opened a pint of Ben & Jerry’s “World’s Best Vanilla” and then threw it out. After seeing the brown inner lid, he decided that his pint must have been used for chocolate before it was used for vanilla. Or, he said, “The entire pint has gone bad and somehow turned the sides brown.” Whatever the reason, he wasn’t’ taking any changes. He wanted his money back.

TASK: Write a letter that explains the brown carton, justifies the reason for using it, and retains the customer’s business.
