Understand the interaction between security and system usability and the importance for minimizing the effects of security mechanisms.

Box 1 contains 3 red balls, 5 green balls and 2 white balls. Box 2 contains 5 red balls, 3 green balls and 1 white ball. One ball of unknown color is transferred from Box 1 to Box 2. (a) What is the probability that a ball drawn at random from Box 2 is green? (b) What is the probability that a ball drawn from Box 1 is not white?

Now that you have completed your decision matrix, you will discuss your decision-making process and how you have used the matrix. For this discussion, you should NOT post your matrix but rather use it as a tool to evaluate your business. In your initial post, address the following: Explain how you could use the matrix in a different business/technology scenario. Give an example. What was the most challenging part of applying this matrix to the final project? What recommendations would you make to change your project, given some of the challenges you faced?Now that you have completed your decision matrix, you will discuss your decision-making process and how you have used the matrix.

How does Hobbes perceive the "state of nature" as contributing to his work? How does Rousseau see it? Which of these thinkers do you agree with most? Explain your position using course materials.

Assuming that you are recently joined as an Accounting technician in Barka Egg Factory in Muscat. Your duty is
to record and maintain every monetary transaction of an organization. At the end of the year, you have prepared a
Trial balance to check the arithmetic accuracy of the transactions. You are surprised that your Debit balance of OMR
5,800 are more than your Credit Balance. Later you discovered that you have committed so many errors while
recording and posting the transactions.
Required:

a) Prepare a Trial balance showing the above shortage of debit balance.

b) What type of error you have committed while recording and posting the transactions? Explain in detail
atleast any four types of errors which you have committed with an example of each error.

** Students are asked to prepare a trial balance with atleast 30 accounts such as Purchase, Sales, Various
expenses and income etc. (Imaginary figure can be used).

In a restaurant that allows smoking, your consumption of cigarettes may have a negative effect on my enjoyment of a restaurant meal. Yet you do not in any way pay for this negative effect on me.

a. (5 points) From this information, decide on the type of externality your consumption creates in the market for cigarettes. Explain in detail, using words and an appropriate graph, the nature of the externality.

b. (5 points) In your graph denote the magnitude of the excess burden (deadweight loss) arising from this externality.

c. (5 points) Now assuming that this externality is the pre-existing distortion in the market, there is an additional tax imposed on the buyers of cigarettes. What do you expect would happen to the excess burden (deadweight loss) of this tax? Describe in words how the graph would alter with the tax and draw a new graph to show the effect on the excess burden (deadweight loss).

d. (5 points) Discuss if the theory of second best holds in this case.

1.Which one of the following statements about refinement and abstraction is TRUE?

Select one:

Abstraction and refinement are the same.

The process of describing more detail about how an instruction should be carried out is called abstraction.

Abstraction is the hiding of details that are not currently important.

Stepwise refinement is only possible with algorithms and not pseudocode.

Lower level details of how an abstracted algorithm is carried out never have to be written.

2.

What is the data type of the expression ’True’ ?:

Select one:

floating point

floating point

boolean

string

list

3.Which one of the following about data is FALSE?

Select one:

Data can only be in the form of strings.

Data is information.

Computer programs need data to do anything useful.

All input and output is data.

At a low enough level of abstraction, all data is numbers.

Create your own hypothetical capital budgeting project.

Make up a company (it could be real or fictional) and make up/describe a potential project for that company (you should be able to do this in one or two sentences…don’t worry about extreme detail).

1.Create a cash flow stream for this project (the cash flow stream should be between 4-7 years in length), a critical acceptance level (T), and a required return (k). (Hint: Your cash flows must exceed your initial investment and your critical acceptance level must be less than the length of the project).

2. Calculate the PP, IRR, and NPV for your project

3.For each decision technique, identify whether or not that technique suggests you should accept or reject the project

Overall, identify whether or not you should accept or reject the project and why. Note that part D is asking for 3 answers (one for each decision technique) while E is just asking for one answer – what is your final recommendation. Also, why doesn’t need to be a long answer, just a few words.
