1. Campbell Corporation is planning to add a new machine to its current plant. There are two machines it is considering, with cash flows as follows:

Machine A       0             1              2          3           4         

                  -10,000      4000         4000    4,000     4000      

Machine B       0                  1                   2                  3

                      -5,000         3,000            3,000          3,000           

Which machine should Campbell choose? Assume the cost of capital is 9%.

Randomly selected students in a statistics class were asked to report the number of hours they slept on weeknights and on weekends. At α = 0.05. Can it be claimed that the scores on 2 tests are correlated on 0.01 significance level?

Student #: 1 2 3 4 5 6 7 8

Test 1: 67 88 76 88 91 95 79 71

Test 2: 69 78 76 84 86 96 70 68

Explain why the classical theory of light as an electromagnetic wave (or of electrons as particles) is unable to explain the following phenomena whereas quantum mechanics is successful.

1. (1) The turn-on voltage of differently colored LEDs

2. (2) The existence of transparent conductors

3. (3) The decrease in frequency of photons scattered off of atoms

4. (4) The spectrum of blackbody emission

For each, use 2-3 sentences, 1-2 equations, and a diagram to provide an explanation that is concise yet precise.

1. 3 Sn2+(aq) + 2 Al(s)??2 Al3+(aq) + 3 Sn(s). What is the voltage for this cell?

2. What is the Gibbs Free Energy for the above reaction assuming standard conditions?

3. What is the Gibbs Free Energy for the cell in question 1 if the Sn2+(aq) is [.15] and Al3+(aq) is [1.80]?

4. Describe what happens within the salt bridge between the two cells

1 (10 pts) Give a big-θ bound for the solutions of the following recurrence relations. Show work.

(a) T(n) = 8T(n/2) + n^3 + 100n

(b) T(n) = 5T(n/4) + 3n

(c) T(n) = 7T(n/3) + 100n^2

(d) T(n) = 3T(n/3) + 1000√ n

(e) T(n) = T(n − 1) + n^2

How to fix this debugging in java

Problem Debugging

This problem is to assign a value to num2 based on the input value of num1. It should then print both numbers.

int num1 = 0;

int num2 = 0;

System.out.print("Enter a number - 1, 2, or 3: ");

num1 = keyboard.nextInt();

if (num1 == 1);

num2 = 2;

else if (num1 == 2);

num2 = 3;

else if (num1 == 3);

num2 = 4;

System.out.println("num1 = " + num1 // + " and num2 = " + num2);

System.out.println("\n");

As a nurse explain the importance of these.

1)Nurses’ potential impact on the environment/supra-system.

2)Holistic nursing care nourishes the whole person—the body, mind, and spirit.

3)Patients should always be told the truth about their diagnoses

4)Severely impaired infants should be kept alive, regardless of their future quality of life.

5)Nurses should be role models of healthy behavior.

1)Nursing research tests and refines the knowledge base of nursing.

2)Theory-based practice

3)Conceptual Models of Nursing

4)Middle-range theories

5)Grand Theories

The importance of these in the nursing field.
