Question 3: A freshman class consists of 6 students, 3 of which are girls. The class needs to select a committee of 2 to represent them in the student senate.

(1) Write the sample space of this experiment.
(2) Calculate the probability of a committee of two boys. (3) Calculate the probability of one boy and one girl.

A boy decides to toss a rock over a cliff. If the mass of the rock is 0.5 kg and he tosses it horizontally with a velocity of 10 m/s, how long will it take the rock to hit the water if the cliff where he is standing is 175 m above the ocean? What is the magnitude of its velocity when it hits?

1.We have learned that bond prices move inversely to interest rates as shown in this graphic. Why is this true? Please explain your answer thoroughly.  

2. The Margaret Anne Dance Company issued a $1,000, 30-yr bond 4 years ago with a 4.0% coupon that pays semiannually. The bond is currently priced at $1,040.

What is the Yield to Maturity (YTM) of this bond?

3. If the Yield to Maturity (YTM) changes to 4.75%, what is the new price of the bond?

4. Two bonds have the identical coupon rates of 5.00%. One has a maturity of 2 years and the other has a maturity of 20 years. Which bond’s price is more sensitive to changes in market interest rates?

1. Assume we have the following resources: • 4 graphic displays • 3 printers • 1 disks Consider we have already allocated these resources among four processes as demonstrated by the following matrix named Allocation. Process Name Graphics Printers Disk Drives Process A 0 1 0 Process B 0 0 1 Process C 0 1 0 Process D 1 0 0 The following is the matrix to show the number of each resources requested; we call this matrix Request. Process Name Graphics Printers Disk Drives Process A 2 0 0 Process B 2 2 0 Process C 1 0 1 Process D 0 2 1 a. Apply Deadlock Detection Algorithm and check whether any deadlock exists. b. Suppose now the Process B requests one additional instance of Graphics, and Process C requests two additional instances of Graphics and one additional instance of Disk Drives, whether this can be granted?

Graphic rating scale is the evaluation of employees’ performance by comparing employees against certain “absolute” standards along a number of performance dimensions.

CASE STUDY 1

Ann is 20 years old and has been working as a graphic designer for 3 years. She earns $35,000 per year in salary after tax. Because her family lives in a country town. Ann had to leave home to find employment and learn to look after herself and her finances.

She shares a flat with 2 friends and pays rent of $150 per week. She estimates that her other weekly expenses, on average, include public transport fares $45; food $120; utility bills $30; mobile phone $30; clothing $50; and miscellaneous expenses $60. She also makes sure that she is saving some of her income and for the past 2 years has arranged for an automatic debit of $300 per month from her bank account into a managed fund. The amount accumulated in the fund comprises the original $2500 she was given for her eighteenth birthday to start the fund and contributions and earnings of $7500, making a total sum of about $10,000. The managed fund is a balanced fund. Any money left over after expenses and investment is kept in her bank account, which totals $2000.

Ann’s main goal is to buy a car in the next 6 months if she can afford it. She will use some money in her managed fund if she has to, but hopes to buy a car valued at about $13000 plus insurance of $750 p.a. she is prepared to take on some extra work in a restaurant to earn another $150 per week in cash to help her to meet her goal.

1. Clearly state Ann’s short-term goal.
2. How would a financial counsellor help Ann to determine whether she may be on target to meet her goal?
3. Prepare a budget for Ann’s income and expenses to assist her to meet her objective.
4. Suggest some budgetary measures to help Ann accumulate her funds. Is there any other advice you may offer to help her achieve her goal?
