Consider the following daily time series for days 1-14. Use this information to answer the questions below.

Step 1 of 7: What is the 3-day Moving Average forecast for time period 4?
Round to the nearest whole number.

Step 2 of 7: What is the 3-day Moving Average forecast for time period t = 15?
Round to the nearest whole number.

Step 3 of 7: Using the 3-day Moving Average forecasts for t = 4 thru t = 14 only, calculate the MAD.
Round the MAD value to the nearest whole number..

Step 4 of 7: What is the 4-day Moving Average forecast for time period 5?
Round to the nearest whole number..

Step 5 of 7: What is the 4-day Moving Average forecast for time period t = 15?

Step 6 of 7: Using the 4-day Moving Average forecasts for t = 5 thru t = 14 only, calculate the MAD.
Round the MAD value to the nearest whole number.

Step 7 of 7: Compare the MAD values for the 3-day Moving Average forecasts and the 4-day Moving Average forecasts.
Which set of forecasts --- 3-day or 4-day Moving Averages -- is preferred and why?

Can you please explain through excel? Any help would be appreciated!

Lab 7: 2D Arrays

Project Goals

The goals of this project are to:

1.       Get students familiar with 2D arrays

2.       Continue loop practice

Important Notes:

1.        Formatting: Make sure that you follow the precise recommendations for the output content and formatting: for example, do not change the text of the problem from “Enter the number of rows in your array: ” to “Enter the number of rows: ”. Your assignment will be auto-graded and any change in formatting will result in a loss in the grade.

2.       Comments: Header comments are required on all files and recommended for the rest of the program. Points will be deducted if no header comments are included.

Problem 1

Save your program as squaring.c

It’s better to be odd, so let’s square those values. Write a program which gets values into an array and then squares the odd values. The program should prompt the user to enter the number of rows -1[1] and columns they would like in an array. Then it should prompt the user to enter values to fill that array. It should iterate over all the values in the array and square any which are odd. Display those values back to the user.

The program should function as follows (items underlined are to be entered by the user):

Enter the number of rows in your 2D array: 2

Enter the number of columns in your 2D array: 2

Enter a value to save: 1

Enter a value to save: 2

Enter a value to save: 3

Enter a value to save: 4

1 2

9 4

Run your program again, testing it with different values.

Notes:

• You know the range and step, which loop is best?
• Know which variables to initialize!

[1]I think this should be ...rows... and not ...rows-1...

Quality Improvement and Profitability Objective Gagnon Company reported the following sales and quality costs for the past four years.

Assume that all quality costs are variable and that all changes in the quality cost ratios are due to a quality improvement program.

Year Sales Revenues Quality Costs as a Percent of Revenues (I only need the answer to the third required part in bold please)

Year 1 $9,600,000 30%

Year 2 10,400,000 27%

Year 3 12,320,000 23%

Year 4 15,320,000 19%

Required: 1. Compute the quality costs for all four years. Quality Cost Year

Year 1 $ 2,880,000

Year 2 $ 2,808,000

Year 3 $ 2,833,600

Year 4 $ 2,910,800 (These answers are correct.)

By how much did net income increase from Year 1 to Year 2 because of quality improvements? $ 312,000 (correct)

By how much did net income increase from Year 2 to Year 3 because of quality improvements? $ 492,800 (correct)

By how much did net income increase from Year 3 to Year 4 because of quality improvements? $ 612,800 (correct)

Required 2. The management of Gagnon Company believes it is possible to reduce quality costs to 3 percent of sales. Assuming sales will continue at the Year 4 level, calculate the additional profit potential facing Gagnon. $ 2,451,200 (correct)

Is the expectation of improving quality and reducing costs to 3 percent of sales realistic? Yes (correct)

Required 3. Assume that Gagnon produces one type of product, which is sold on a bid basis. In Years 1 and 2, the average bid was $200. In Year 1, total variable costs were $120.00 per unit. In Year 3, competition forced the bid to drop to $160.00. Do not round the intermediate calculations and round your final answers to the nearest dollar.

Compute the total contribution margin in Year 3 assuming the same quality costs as in Year 1. $

Now, compute the total contribution margin in Year 3 using the actual quality costs for Year 3. $

What is the increase in profitability resulting from the quality improvements made from Year 1 to Year 3? $

I need the third part in bold more than anything. Thank you for your time.

find the general solution

2xy^3+e^x+(3x^2y^2+siny)y'=0

xy'=6y+12x^4y^(2/3)

(2x+1)y'+y=(2x+1)^(3/2)

Three-Day Diet Record and Computer Analysis

Recording Your Diet

1. Record all the food and liquids you consume during a 3 day (72 hour) period. To eliminate forgetting

something, write it down as soon as you are consuming it. You can use a tablet, notes app on your

phone, anything that works for you.

2. It is best to select 2 weekdays and 1 weekend day to record since often a person's diet differs on the

weekend from the rest of the week (not necessary but helpful). Also to make this meaningful eat as you

normally would. Remember you are not graded on how healthy or unhealthy you are eating.

3. Describe food/beverage as completely as possible. The more descriptive you are about the

food/beverage the more accurate your diet analysis will be. You will use these descriptors when looking

for the food in the database on iProfile. You need to know:

Amounts - These should be measured as follows:

●

For liquids: record the amount using volume measurements. Use cups or tablespoons or

teaspoons to describe the amount you consumed.

●

For solid food: Choose one of the following depending on the food. Weight = pound, ounces,

grams, kilograms

●

Volume = cups, tablespoons, teaspoons Count = each

●

Use decimals (example: 0.5 cups of milk) and NOT fractions (example: NOT 1/2 cup of milk) for

amounts. Some common fractions: 1/8 = 0.12 1/4 = 0.25 1/3 = 0.33 1/2 = 0.5 2/3 = 0.67 3/4 =

0.75

Some useful rules of thumb for estimating the quantity of foods:

●

3-ounces serving of meat is about the size of the palm of a woman's hand or a deck of cards.

●

1.5 (= 1 1/2) ounce piece of cheese is the size of a nine-volt battery.

●

1 ounce piece of cheese is the size of a pair of dice.

●

A standard slice of lunch meat or American-type cheese weighs 1 ounce.

●

0.5 (=1/2) cup serving is about the size of a tulip.

●

1 cup serving is about the size of baseball.

●

1 ounce slice of bread is about the size of a CD case.

●

For mixed dishes like lasagna, tuna casserole, etc., you will need to estimate each of the foods in

the dish. Example: For 1 cup of tuna casserole you could have 3/4 cup pasta, 1/4 cup tuna, 1/4

cup cream of mushroom soup.

Description - The more detailed the description the easier it will be for you to select foods in the

computer database that represent the food/drink you actually ate. Examples of the types of information

you need are:

●

fat content

●

type of flour used (white, rye, whole wheat, wheat)

●

type of meat (prime rib, lean hamburger (10% fat), flank steak, etc.) , fish (salmon, trout, etc.) or

poultry (white or dark, skin or no skin)

●

juices: frozen concentrate, fresh, or powder

●

list all condiments and the amounts of each ( mayonnaise, mustard, ketchup, relish, etc.)

Other important items:

●

DO NOT list vitamin and mineral supplements or other types of supplements (with the exception

of protein powder) on the 3 day food record. This assignment is looking at your food intake.

●

Record all the water you drink.

●

Record all the alcoholic beverages you consume.

Remember this project will be much more interesting if it reflects what you really eat and drink.

Therefore, be as accurate as possible when measuring the amount and giving a description of the

food/drink.

When you have two dice rolling at the same time, find the following probabilities with proper explanations.

(2) When you will observe a total of 4 or a total of 6

(3) When you will observe at least a total of 2
