3) (CuSO₄ + AgNO₃)

4) (AlCl₃ + AgNO₃)

5) (Zn(C₂H₃O₂)₂ + AgNO₃)

6) (Pb(NO₃)₂ + AgNO₃)

1). Which predictor variables are statistically significant at the 10% significance level?

2). What is the slope and p-value of the bedrooms variable?

3). What percentage of the variability in price is explained by this model?

Trace the following code segment

1. use the red numbers under each statement to show the order that you execute the code by.

For example: (1) means int p=3; (2) means p<10; (3) means p+=3;

(1)(2)(3) means you execute int p=3 then p<10 then P+=3;

(2)(1)(3) means you execute p<10 then int p =3 then P+=3;

2. show its output:

int x = 30,  num = 100;

    (1)   

while ( x > 0)

(2)

          {

cout   <<   endl

                         <<  “ x =“   <<   x    <<   “ “   <<   “num =”   <<   num;

  (3)

              x   - = 10;

  (4)

num += x;

(5)

}

1.         What is the price of a $1,000 par value bond with an 8% coupon rate paid annually, if the bond is priced to yield 8% and has 9 years to maturity?

2.         What would be the price of the bond in #1 if the yield decreased to 6%?

3.         What would be the price of the bond in #1 if the yield rose to 10% and was callable at 110% of par in 4 years?

4.         What is the yield to maturity for a Zero Coupon Bond that has 15 years left to maturity and is selling for $209?

The XYZ Company is performing capital budgeting to decide whether to build a factory to produce bicycles.

The factory will cost $1 million at time 0 and $1 million at time 1.

It will result in positive cash flows of:

The factory will be sold at time 6.

The opportunity cost of capital is 4% effective.

Find the minimum sale price at time 6 to make the factory a desirable investment.

A plane is missing, and it is presumed that it was equally likely to have gone down
in any of 4 possible regions. Let 1 βi, i = 1, 2, 3, 4, denote the probability that
the plane will be found upon a search of the ith region when the plane is, in fact, in
that region. (The constants βi are called overlook probabilities, because they represent the probability of overlooking the plane; they are generally attributable to the
geographical and environmental conditions of the regions.) What is the conditional probability that the plane is in the 1st region given that a search of region 1 is
unsuccessful?

Explain briefly what the following algorithm does and write the output below: (5 credits)

Step 1: Set sum equal to 0, set n equal to 1

Step 2: Repeat steps 3, 4 and 5 until sum > 60

Step 3: Set sum equal to sum + n2

Step 4: Replace n with n +1

Step 5: Print n and sum on a new line

Step 6: Stop

Show output:

c) Suppose x = -2 and y = 9. What is the sum of both players' payoffs in all pure strategy Nash equilibria of the game?

d) Suppose x = 3 and y = 9. How many rationalizable strategies does Player 1 have?

e) Suppose x = 3 and y = 9. How many rationalizable strategies does Player 2 have?

f) Suppose x = 3 and y = 9. What is the sum of both players' payoffs in all pure strategy Nash equilibria of the game?

JAVA Point of Sale System
The McDowell Restaurant chain has asked you to write a menu program for their new Fast-food
service machines. Your program already prints the following menu like this:
**********************************************************************
McDowell’s Restaurant
**********************************************************************
Make your selection from the menu below:
1. Regular Hamburger $1.50
2. Regular Cheeseburger $1.75
3. Fish Sandwich $2.50
4. Half-pounder with cheese $2.75
5. French Fries $0.99
6. Large Soft Drink $1.25
***********************************************************************
Select 1, 2, 3, 4, 5, or 6 ----- >
Your program must now read the customer’s selection and compute the total price of their
purchase, including 6.5% sales tax.
Input
The first line of input represents N, the number of test cases. The additional lines consists of a
sequence of integers scoped between 1 to 6. Each number should indicate a selection from the
above menu to be purchased.
Output
The program should print the sum of the orders plus tax as “Please pay $<dollars>”, where
<dollar> is the total amount of the purchase then conclude with “Thank you for eating at
McDowell’s”.

Sample Input Sample Output
1
1 4 4 5 3 1 Please pay $12.77
Thank you for eating at McDowell’s!
