NOTE: For full points, you must provide a solution, not merely an answer. Use each question’s message box to explain how you arrived at your answer. Here is an example:
Question: Convert hexadecimal 4C to decimal.
Solution:
C in hex is 12 in decimal.
4C = 4 x 16 + 12
4C = 64 + 12
4C = 76 in decimal.

need B and C plates calculations and need all calculations to be shown please

10 grams of soil are placed in 40 ml of water (A). One ml of (A) is placed in 99 ml of water (B) 0.01 of (B) is placed in 9.99 ml of water (C). Dilutions (B) and (C) are plated in triplicates 0.1 ml in each plate.

After 24 hours incubation at 37 degrees Celsius, these are the results:

Plate B-1 counted 102 colonies

Plate C-1 counted 10 colonies

B-2 counted 152 colonies

C-2 counted 12 colonies

B-3 counted 111 colonies

C-3 counted 11 colonies

Calculate the number of bacteria per gram of soil. (Show ALL calculations!)

…. So far what I have

For the above mentioned example, the plate ‘B’ should be used for calculating the number of bacteria taking into consideration that it contains colonies which are in the range of 30 to 300.

The dilution factor for the plate can be calculated as follows :-

DF = initial volume / final volume

= 1ml / 100 ml

= 10-2

Number of bacterial colonies = CFU in plate / (Amount of diluent added) x (Dilution factor)

Plate B1

CFU/ml = 102 / (0.1)(10-2) = 102 x 103

Plate B2

CFU/ml = 152 / (0.1)(10-2)

= 152 x 103

Plate B3

CFU/ml = 111 / (0.1)(10-2)

= 111 x 103

Taking an average, we get (102 + 111 + 152 x 103 / 3 = 121.66 x 103) bacteria or CFU / gram of soil.

Tasks to perform.

Here are the specific tasks that you need to do:

For the personal business scenario you have chosen (please provide a short description of the scenario) or the Mobility case,

• List all the symptoms of the problems faced by the business area that you are analyzing.Identify and list the possible underlying problems. If symptoms are cascaded (meaning some problems are symptoms to other deeper problems, then present them in indented bullet points to show the relationships. Limit yourself to up three stages of cascading. (10 points)
• Identify and list from a systems perspective, the various systems components, such as the environmental elements, inputs and outputs, various sub-systems, etc.Draw a systems diagram in PowerPoint (or in any other program that you know). (10 points)
• Identify and list the various types of interfaces between the sub-systems and associate the symptoms listed in part 1, with the various sub-systems and interfaces. (5 points)
• Develop a process list and a process flow diagram (including swim lanes) for the activities for the chosen business scenario or the case. (15 points).To do that you may want to answer the following questions:
  • What are the sub-systems identified in part 2?
  • Who are the actors within each of the sub-systems?
  • What will be a possible list of processes that each of the actors execute?
  • Who is the owner of each of the processes, how much time does it take to complete a process and what interfaces does it use?Are they synchronous or asynchronous?
  • What will be the customer processes?
• From the above process flow diagram, identify and list all the friction points and their causes.Remember that frictions are created by incorrect and inefficient interface usage, long chain or processes, and processes with loops. Based on your identification, circle the processes that you think are in need of change (10 points).
• Select between 3-4 processes from PFD and develop a SIPOC chart for them. (10 points)
• Associate the processes that you have identified in your PFD with the value activities of the business.For this, you have to have a clear understanding of the processes and value activities.For a grocery store, for example, the storing of the shelves are inbound logistics, the actual selling process (including the checkout) is operations, special offers and coupons are part of marketing and sales, etc.Note that your PFD may not include processes from all of the value activities and that is OK.Just identify the ones that are associated with your processes. (10 points)
• Suggest a competitive strategy that your business should adopt.Based on that strategy, and using Porter’s Competitive Strategy model, identify the main competitive forces that your business should pay attention to and identify the value activities where changes are to be made for the company to remain competitive.(10 points)
• Using the result from the analysis and the value activities identified above, identify the major changes in business processes within each of the value activities required by your business and based on the analysis, develop an information technology plan that can help the company to become more efficient and effective.(10 points)
• Write a one page memo/description of your findings clearly articulating the problems, your analysis and solutions.This is more of a summary of the work that you have done in step 1-10 above. (10 points)
• BONUS Points. Create a PFD with the changed processes that you have suggested in part 9.

1. Amka is the head analyst for the Alaska Department of Fish and Game Service. Recently the agency has become concerned about overfishing in the waters off Alaska. Amka is estimating the demand curve for salmon as part of the agency’s mitigation efforts. From past statistics she knows that when the price of a freshly caught salmon is $400, the public will demand a quantity of 1 million fish. If the price is $200 then the public will demand 5.6 million fish. Finally, if the price was $125 consumers will demand a quantity of 8 million fish. Which curve below could be the correct demand curve for Alaskan salmon given these three data points?
