. Draw a value chain for a hotel you know well or have researched. Explain the implication of your study for competitive advantage.

1. The equation of the line with an x-intercept of 33 and a y-intercept of 44 can be written in the form y=mx+b where
the number m is:    
the number b is:    

Enter each answer as a reduced fraction (like 5/3, not 10/6) or as an integer (like 4 or -2).

2. You have filled your car with a full tank of gas, and could travel 485 miles. For every 17 miles you drive, you use 1 gallon of gass (17 miles per gallon).

Please write an equation in slope-intercept form to model this situation. Please use m for the the miles you've traveled, and g for the gallons of gas you use.    

Whenever you are asked to test a hypothesis, be sure to: (a) state the null and alternative hypotheses; (b) state the relevant sample statistic; (c) give the rejection region; (d) compute the test; (e) give your decision and a conclusion in English.

1. Assume that last year, licensed American drivers drove an average of 10,000 miles, with a standard deviation of 2,000 miles (these are population figures).  This year, the government campaigned to get people to save gas by driving less.  To test the effectiveness of the campaign, a study is conducted.  A sample of 100 drivers is drawn at random from the general population and the number of miles driven by each person is recorded.  On the average, these 100 drivers drove 11,000 miles.  Was the campaign effective?  Use alpha = .01.

Question 1
Sydney Tour Company purchased a van for $150,000. The company expected the van to be used for 10 years, or 200,000 miles, with an estimated residual value of $2,000 at the end of that time. Actual usage of the van for the first 3 years were as follows:
 Year 1: 5,000 miles
 Year 2: 10,000 miles
 Year 3: 12,000 miles
Required
a) Calculate the depreciation for the second year under each of the methods below
I. Straight-line
II. Units of production
b) Show how the asset of van would appear in the balance sheet prepared at the end of the second year if the straight-line method was used
c) What factors should be considered in the selection of a depreciation method?

Russell Preston delivers parts for several local auto parts stores. He charges clients 0.85 per mile driven. Russell has determined that if he drives 3,000 miles in a month, his average operating cost is $0.75 per mile. If he drives 5,000 miles in a month, his average operating cost is $0.55 per mile. Russell has used the high-low method to determine that his monthly cost equation is: total cost = $1,320.00 + $0.25 per mile.        

Required:
1. Determine how many miles Russell needs to drive to break even.



2. Assume Russell drove 2,600 miles last month. Without making any additional calculations, determine whether he earned a profit or a loss last month.

3. Determine how many miles Russell must drive to earn $1,500.00 in profit.

  

4-a. Prepare a contribution margin income statement assuming Russell drove 2,600 miles last month. (Enter your answers rounded to 2 decimal places.)

  

4-b. Use the above information to calculate Russell’s degree of operating leverage. (Round your answer to the 2 decimal places.)

Russell Preston delivers parts for several local auto parts stores. He charges clients 0.90 per mile driven. Russell has determined that if he drives 2,100 miles in a month, his average operating cost is $0.60 per mile. If he drives 3,100 miles in a month, his average operating cost is $0.50 per mile. Russell has used the high-low method to determine that his monthly cost equation is: total cost = $1,220.00 + $0.29 per mile.   

1. Determine how many miles Russell needs to drive to break even.

2. Assume Russell drove 2,500 miles last month. Without making any additional calculations, determine whether he earned a profit or a loss last month.

3.Determine how many miles Russell must drive to earn $2,135.00 in profit.

4. Prepare a contribution margin income statement assuming Russell drove 2,500 miles last month. (Enter your answers rounded to 2 decimal places.)

Programming 3: Multi-Way Branching

Shipping Charges

The Fast Freight Shipping Company charges the following rates:

• Given the Weight of Package (in Kilograms), use the following Rate ($) per 500 Miles Shipped.

• 2 kg or less = $1.10 per 500 Miles Shipped

• Over 2 kg but not more than 6 kg = $2.20 per 500 Miles Shipped

• Over 6 kg but not more than 10 kg = $3.70 per 500 Miles Shipped

• Over 10 kg but not more than 20 kg = $4.80 per 500 Miles Shipped

Write a program that reads the weight of the package and the distance it is to be shipped, and then displays the charges to two decimal points.

• Input Validation:
• Do not accept values of 0 or less for the weight of the package.
  • Print "ILLEGAL WEIGHT: BELOW MINIMUM"
• Do not accept weights of more than 20 kg (this is the maximum weight the company will ship).
  • Print "ILLEGAL WEIGHT: ABOVE MAXIMUM"
• Do not accept distances of less than 10 miles or more than 3,000 miles. These are the company’s minimum and maximum shipping distances.
  • Print "ILLEGAL DISTANCE"

I got stuck here:

#include
using namespace std;

int main(){
int i=0,miles;
   double j,weight,cost,distance;

   cin>>weight;
      if(weight<=0){
         cout<< "ILLEGAL WEIGHT: BELOW MINIMUM" << endl;
      }
      else(weight>20){
         cout<< "ILLEGAL WEIGHT: ABOVE MAXIMUM" << endl;
      }
       

   cin>>distance;
      while(distance<10 || distance >3000){
         cout<< "ILLEGAL DISTANCE" << endl;
      }
   i=miles/500;
   j=miles%500;

   if(j>0){
       i=i+1;
   }
   if(weight<=2){
       cost=i*1.10;
   }
   else if(weight>2 && weight<=6){
       cost=i*2.20;
   }
   else if(weight>6 && weight<=10){
       cost=i*3.70;
   }
   else if(weight>10 && weight<=20){
       cost=i*4.80;
   }
   cout<<"Cost of Shipping: " << cost;
   return 0;
}

Random inputs are....

Input : -1 2000

Expected inputs are : ILLEGAL WEIGHT: BELOW MINIMUM

Input: 1 5000

Expected output : ILLEGAL DISTANCE

input: 2 2000

Expected output : 4.40 (<--| enter symbol)

Please revise and let me know what i did wrong.....

You are an accountant for a large department store and have been given the assignment of developing a model to predict the amount of time it takes to process invoices. Data is collected daily for 32 consecutive working days, and the number of invoices processed and completion time (in hours) are stored under the tab Invoice in the Excel data file for this homework.

a. Create the appropriate scatter plot and calculate the coefficient of correlation. Comment on the results. Does it appear a linear relationship exists?

b. Use the least-squares method to compute the regression coefficients b₀ and b₁.

c. Interpret the meaning of b₀ and b₁ in this problem.

d. What if the predicted mean amount of time it would take to process 150 invoices? Include a confidence interval for this prediction.

e. Determine the coefficient of determination, R², and explain its meaning in this problem.  

g. Perform a complete residual analysis. Does the analysis support all the assumptions required for a valid model? Explain.

h. Based on your results in part g, what can you say about the validity of the prediction you made in part c?

h. What conclusions can you reach about the relationship between then number of invoices processed and the completion time? What actions, if any, would you take next?
