A firm is considering Projects S and L, with the following cash flows:
Project L: −$2,150 in year 0, $765 in years 1, 2, 3, and 4
Project S: −$1,025 in year 0, $380 in years 1, 2, 3, and 4
These projects are mutually exclusive. The projects are also equally risky with WACC of 6%. The CEO wants to use the IRR criterion, while the CFO favors the NPV method. You were hired to advise the firm on the best procedure. If the wrong decision criterion is used, how much potential value would the firm lose?

a. $188.68

b. $230.49

c.$198.61

d.$209.07

e. $219.52

Bank Accounts in Java!

Design and implement a Java program that does the following:

1) reads in the principle

2) reads in additional money deposited each year (treat this as a constant)

3) reads in years to grow, and

4) reads in interest rate

And then finally prints out how much money they would have each year.

See below for formatting.

Enter the principle: XX

Enter the annual addition: XX

Enter the number of years to grow: XX

Enter the interest rate as a percentage: XX

Year 0: $XX

Year 1: $XX

Year 2: $XX

Year 3: $XX

Year 4: $XX

Year 5: $XX

A random sample of 10 examination papers in a course, which was given or fail basis, showed the following scores. (PAPER NUMBERS) (GRADES) (STATUS) 1 85 Pass 2 87 fail 3 92 Pass 4 85 Fail 5 79 Pass 6 90 Pass 7 88 Fail 8 74 Pass 9 79 fail 10 91 pass 1. estimate the probability that the grade will be more than 85. 2. estimate the probability that the proportion of fail will be less than 0.65. 3. Estimate the 97% confidence interval for grade. 4. Estimate the interval of proportion for pass at the 98% confidence level.

An ideal Rankine cycle operates between 2700 psia and 1050° F at throttle and 4 psia in the condenser. One high pressure open type feed-water heater and one low pressure open type feed water heater are placed at 700 psia and 190 psia respectively. a) Draw the schematic flow and T-S diagrams of the cycle [3] b) Calculate mass flow rate in the both heaters. [2] c) Calculate heat rejected. [2] d) Calculate cycle efficiency. [4] e) Calculate work ratio. [1] Assumption: 1 lbm/h flow at turbine throttle and no flow pressure drops.
