Using internal controls to prevent errors. The following misstatements occurred in the records of MW Company. For each misstatement, suggest a control to prevent it from happening. 1. A bill from a supplier was paid for goods that had not been ordered. 2. A supplier's bill for 50 boxes of materials was paid even though only 40 boxes were received. 3. Expensive product components were stolen by an employee from a loading dock area after hours. 4. No bill was sent to a customer for a shipment because the shipping document was lost after the shipment was made.

Using readily available data, plot two yield curves:

1. One from January 2017
2. One from January 2019

Based on your understanding of the signals sent by the yield curve:

1. What has happened to the shape of the curve over the last two years?
2. What does this mean for the stock and bond markets?

question one 100 kg of a gas has the following mass composition: 19.3% CO2, 6.5% O2 , 2.1% H2O and 72.1% N2

What is the mole fraction of each component in the mixture?

Molecular weight of (CO2= 44, O2=32, H2O=18, N2=28)

question two The density of a certain solution is 1.05 g/cm3 at 25°C. How many cubic meters will be occupied by 5000 kg of this solution.

A 1.8 kg , 20-cm-diameter turntable rotates at 130 rpm on frictionless bearings. Two 510 g blocks fall from above, hit the turntable simultaneously at opposite ends of a diameter, and stick.What is the turntable's angular velocity, in rpm, just after this event?

1. Create a PHP program containing an multi dimensional array of all the first and last names of the students in your class. Sort the array by last name in alphabetic order. Also sort the array in reverse order.

2. Split the array from #1 into two arrays; one containing first names, the other containing last names.

X Company is considering replacing one of its machines in order to save operating costs. Operating costs with the current machine are $68,000 per year; operating costs with the new machine are expected to be $38,450 per year. The new machine will cost $156,000 and will last for five years, at which time it can be sold for $3,000. The current machine will also last for five more years but will not be worth anything at that time. It cost $45,000 four years ago, but its current disposal value is only $6,000. Assuming a discount rate of 8%, what is the incremental net present value of replacing the current machine?

b. Assume the following two changes: 1) both machines will last for six more years, 2) the salvage value of the new machine after six years will be zero. If X Company replaces the current equipment, what is the approximate internal rate of return?

Write a program call FancyMyName which asks you to write a program that tests the usage of different methods for working with Strings.

This program will ask the user to enter their first name and their last name, separated by a space.

Read the user's response using Scanner. Separate the input string up into two strings, one containing the first name and one containing the last name. You can accomplish this by using the indexOf() hint*** find the position of the space, and then using substring() to extract each of the two names. Also output the number of characters in each name (first & last) and output the user's initials. The initials are the first letter of the first name together with the first letter of the last name

A sample run of the program should look something like this:

Please enter your first name and last name, separated by a space?

You entered the name: Steve Henry

Your first name is Steve: has 5 characters

Your last name is Henry: has 5 characters

Your initials are: SH

Production Lines: The data shows the number of defective parts produced by two machines when the factory used two different alloys as the raw material. At .05 significance level comment on the main effects and the interaction effect.

Given that in 4 flips of a fair coin there are at least two "heads", what is the probability that there are two "tails"? There are ten equally likely outcomes: 1, 2, 3, 4, 5, 6, 7, 8, 9, 10. You randomly select one value, call it the initial value. Then, you continue to randomly select values, call them follow-up selections, until you come up with the initial value. What is the fewest number of follow-up selections that insures that the probability is better than one-half that you will observe your initial value? (Note: this problem assumes values are selected "with replacement," which simply means that after each selection, there are still the same ten equally likely outcomes.)
