Carry your intermediate computations to at least four decimal places, and round your answer to at least one decimal place. (If necessary, consult a list of formulas.) The process for solving these problems is fairly long. Aleks recommends: . Then . I watched a video that condenses the process a bit. Its easier to group the sections included in this process into 4 rows and 4 columns. The first column should list the frequencies in the histogram. Next list the midpoints in the 2nd column.

...Homework #1 Calculate the usable area in square feet of a house. Assume that the house has a maximum of four rooms, and that each room is rectangular. Program Description The purpose of this program is to calculate the usable area (square feet) of a four room house. Analysis To calculate the usable area in square feet in the house I would first need to identify the inputs and outputs. I know the house has a maximum of 4 rooms that are rectangular in shape, this is my input. Using the area formula (L x W) I can determine the square feet for each room. Adding the square feet for each room will provide the amount of usable area in square feet of the house and my output for this program.

A change in interest rate will affect the cost of borrowing, the income generated from tangible assets and stock’s value that the financial institution owns that will lead to profits or losses as a result. 2. The Federal Reserve’s Policies such as monetary policy could affect interest rates, inflation, and the supply of the money. These three factors are directly related to the profitability of financial companies. So the managers care so much about the Fed activities. 3. The family members are closed to you than a stranger.

...Problem Definition: The problem here is to calculate the usable area in square feet of house. We are to assume that the house has a maximum of four rooms, and that each room is rectangular. Problem Analysis Objective: Devise a program that calculates the usable area of a house. This is minimally what is being requested. • Outputs: This problem calls for a simple output, the total usable square foot of the house, with a maximum of four rooms, each room being rectangular. Total number of square foot = Area of Room1 + Area of Room2 + Area of Room3 + Area of Room4 • Inputs: The problem will require us to know the length and width of each of the four rectangular rooms in order to compute the correct output, the total number of square foot. The length multiplied by the width of each of the four rectangular rooms will give us area of each room. We will receive these data points by measuring the dimensions of the room. Length1 x Width1 = Area of Room1 • Calculation Approach: In order to calculate the Total Square Foot of the house, we will need to take the sum of the areas of each room. o Area of Room 1 = Length of Room1 x Width of Room1 o (Repeated four times – once for each room) o Total Square Foot of House = Area of Room1 + Area of Room2 + Area of Room3 + Area of Room4 • Define variables: AreaofRoom1 = square foot area of the room 1 AreaofRoom2 = square foot area...

...I.T Consultation For Mr. Green CIS 329 – Administering Desktop Clients August 11, 2013 Mr. Green has decided to implement a network within his small business. This is a good choice in moving forward with his growing operations and size. He has several questions, and already has a few opinions about how he will go about this implementation, including both the software and hardware involved. My job as a private computer consultant will be to clarify some of the common misconceptions made by Mr. Green, and ensure that his network implementation will allow him to reach the goals he has as a small business owner. Mr. Green does not seem to have any interest in a Windows-based server up-front, meaning he will have to use the sharing or home group capabilities found within each computer’s operating system. Mr. Green needs to take into account the fact that Windows 7 Ultimate has little to no benefit over Windows 7 Professional as far as networking is concerned. The only added features he will get with Ultimate include the pre-installation of extra languages, and a service called Bit Locker. Bit Locker is an encryption software similar to an array of open source alternatives found on the internet, so if Mr. Green does not employ non-English speaking employees, he can save a good bit of money buying Windows 7 Professional. With Windows 7 Professional, he also maintains the ability to connect to a domain network if he was to purchase a real...
