1. The Soda class has two fields: a String for the name and a double for the price.

2. The Soda class has two constructors. The first is a parameterized constructor that takes a String and a double to be assigned to the fields of the class. The second is a copy constructor that takes a Soda object and assigns the name and price of that object to the newly constructed Soda object.

3. The Soda class has two getters: one to return the name and one to return the price.

4. The VendingMachine has one field for a Soda. This can initially reference a null object by assigning null to the field.

5. The VendingMachine has one constructor that takes a Soda. Remember to assign a new Soda to the Soda field securely.

6. The addSoda method of the VendingMachine class takes a Soda. Check if the field of the class references a null object (you can use the equals operator to check what the variable references). If the field references a null object, assign the new Soda to the Soda field securely and return true. If the field does not reference a null object, just return false.

7. The removeSoda method of the VendingMachine class takes no arguments. Check if the field of the class does not reference a null object (you can use the equals operator to check what the variable references). If the field does not reference a null object, assign null to the Soda field and return true. If the field references a null object, just return false. 8. In the VendingMachineDemo, change the name and price for the Soda being added to the VendingMachine to any other name and price of your choosing.

Consider the following:

–       You need a $300,000 financing package.

–       $150,000 at 9%, 30 Years

–       $100,000 at 8%, 20 Years

–       $50,000 at 7% 10 Years

1. What is the monthly payment for each part of the financing package?
2. What is the IRR on the $300,000 borrowed?

Does anybody know how to solve these two questions with details?

Please answer the following:

Loan Amortization

Your company is planning to borrow $1.5 million on a 7-year, 8%, annual payment, fully amortized term loan. What fraction of the payment made at the end of the second year will represent repayment of principal? Round your answer to two decimal places.

Thank you!

1. The time to failure for an electronic device is measured as with different operation temperatures and humidity levels. The following data is obtained.

Is there a difference in mean life with different temperature and humidity? Is there an interaction between temperature and humidity? Complete the below table to support your conclusions.

Question 1
Seven baseballs are randomly selected from the production line to see if their stitching is straight. Over time, the company has found that 89.4% of all their baseballs have straight stitching. If exactly five of the seven have straight stitching, should the company stop the production line?
   Yes, the probability of five or less having straight stitching is unusual
   No, the probability of five or less having straight stitching is not unusual
   No, the probability of exactly five have straight stitching is not unusual
   Yes, the probability of exactly five having straight stitching is unusual
  
Question 2

A soup company puts 12 ounces of soup in each can. The company has determined that 97% of cans have the correct amount. Which of the following describes a binomial experiment that would determine the probability that a case of 36 cans has all cans that are properly filled?
   n=36, p=0.97, x=36
   n=36, p=0.97, x=1
   n=12, p=0.36, x=97
   n=12, p=0.97, x=0

Question 3

A supplier must create metal rods that are 2.3 inches width to fit into the next step of production. Can a binomial experiment be used to determine the probability that the rods are the correct width or an incorrect width?
   No, as the probability of being about right could be different for each rod selected
   Yes, all production line quality questions are answered with binomial experiments
   No, as there are three possible outcomes, rather than two possible outcomes
   Yes, as each rod measured would have two outcomes: correct or incorrect
  
Question 4

In a box of 12 pens, there is one that does not work. Employees take pens as needed. The pens are returned once employees are done with them. You are the 5th employee to take a pen. Is this a binomial experiment?
   No, binomial does not include systematic selection such as “fifth”
   No, the probability of getting the broken pen changes as there is no replacement
   Yes, you are finding the probability of exactly 5 not being broken
   Yes, with replacement, the probability of getting the one that does not work is the same
  
Question 5

Sixty-eight percent of products come off the line within product specifications. Your quality control department selects 15 products randomly from the line each hour. Looking at the binomial distribution, if fewer than how many are within specifications would require that the production line be shut down (unusual) and repaired?
   Fewer than 8
   Fewer than 9
   Fewer than 11
   Fewer than 10
  
Question 6

The probability of a potential employee passing a drug test is 86%. If you selected 12 potential employees and gave them a drug test, how many would you expect to pass the test?
   8 employees
   9 employees
   10 employees
   11 employees
  
Question 7

The probability of a potential employee passing a training course is 86%. If you selected 15 potential employees and gave them the training course, what is the probability that 12 or less will pass the test?
   0.862
   0.148
   0.100
   0.852
  
Question 8
Off the production line, there is a 3.7% chance that a candle is defective. If the company selected 45 candles off the line, what is the probability that fewer than 3 would be defective?
   0.975
   0.916
   0.768
   0.037

Fiction Cruiseline offers three ways to exercise on their cruise ships. 73 of the 86 passengers participated in at least one method of exercise. 36 people went rock climbing, 44 people went ice skating, and 19 went to the fitness center. 14 people went rock climbing and ice skating, 11 people went rock climbing and to the fitness center, and 9 people went ice skating and to the fitness center. Draw a Venn Diagram for the three sets if necessary. Include how you found the number of ALL three activities.

Calculate the probability for:

A randomly selected passenger did not go ice skating, given they did at least two activities
