The last digit of a credit card number is the check digit, which protects against transcription errors such as an error in a single digit or switching two digits. The following method is used to verify actual credit card numbers but, for simplicity, we will describe it for numbers with 8 digits instead of 16:

1.) Starting from the rightmost digit, form the sum of every other digit. For example, if the credit card number is 4358 9795, then you form the sum 5 + 7 + 8 + 3 = 23.

2.) Double each of the digits that were not included in the preceeding step. Add all digits of the resulting numbers. For example, with the numbers given above, doubling the digits, starting with the next to last one, yields 18 18 10 8. Adding all digits in these values yields 1 + 8 + 1 + 8 + 1 + 0 + 8 = 27.

3.) Add the sums of the two preceding steps. If the last digit of the result is 0, the number is invalid. In our case, 23 + 27 = 50, so the number is valid.

- IN PYTHON, write a program that implements this algorithm. The user should supply an 8 digit number, and you should print out whether the number is valid or not. If it is not valid, you should print the value of the check digit that would make it valid.

Credit Card Number Check. The last digit of a credit card number is the check digit, which protects against transcription errors such as error in a single digit or switching two digits. The following method is used to verify actual credit card number but, for simplicity, we will describe it for numbers with 8 digits instead of 16: Starting from the rightmost digit, form the sum of every other digit. For example, if the credit card number is 43589795, then you form the sum 5 + 7 + 8 + 3 = 23. Double each of the digits that were not included in the preceding step. Add all the digits of the resulting numbers. For example, with the number given above, doubling the digits, starting with the next-to-last one, yields 18 18 10 8. Adding all digits in these values 1 + 8 + 1 + 8 + 1 + 0 + 8 = 27. Add the sums of the two preceding steps. If the last digit of the result is 0, the number is valid,. In our case, 23 + 27 = 50, so the number is valid. Write a program that implements this algorithm. The user should supply an 8-digit number, and you should print out whether the number is valid or not. If it is not valid, you should print out the value of check digit that would make the number valid.

thanks for help :)

• Starting from the rightmost digit, form the sum of every other digit. For example, if the credit card number is 4358 9795, then you form the sum 5 + 7 + 8 + 3 = 23.

Write a program in Java that implements this algorithm without utilizing arrays. The user should supply an 8-digit number, and you should print out whether the number is valid or not. If it is not valid, you should print the value of the check digit that would make it valid.

The following data represent the​ high-temperature distribution for a summer month in a city for some of the last 130 years. Treat the data as a population. Complete parts​ (a) through​ (c).

Temperature (degrees F)   Lower Limit   Upper Limit   Days
50-59   50   59   1
60-69   60   69   307
70-79   70   79   1467
80-89   80   89   1514

A.

​Yes, the frequency histogram of the data is bell shaped.

B.

​No, the frequency histogram of the data is uniform.

C.

​No, the frequency histogram of the data is skewed left.

A factory that makes stamped parts has a painting operation. All parts must be painted to combat corrosion. The factory has 10 different parts, each of which have an annual demand of 500,000. Typically the factory sets up for one part per day and runs for the entire shift producing just that one part. To keep up with demand, the factory works a six-day work week and two 8-hour shifts, working 50 weeks per year. Each machine can paint 100 parts at a time and the standard cycle time is 15 minutes to paint and cure 100 parts. Approximately 5% of the parts painted must be scrapped due to paint flaws. At the beginning of the day, each paint machine requires 45 minutes to set up. After set up, it is run for the remainder of the 2 shifts (16 hours). Paint booths are notoriously unreliable (clogs, leaks, messes, machinery failures) and shutdowns are commonplace. The plant assumes 20% downtime for each machine to deal with in-process issues. Booths are 100% available for setup. Because it is a tiring job, worker efficiency is 90%. Calculate the number of paint booths required to meet annual demand.? ( ) machines

Experience in modern countries (such as Venezuela) has demonstrated that state ownership of the means of production:
Select one:
a. Often runs in parallel with the public interest as governments make better decisions to help the population
b. Is the most profitable way to organize production
c. Can lead to high levels of corruption
d. Often runs counter to the public interest as industry becomes less efficient
e. Often leads to increased inefficiency, higher prices and higher taxes, and high levels of corruption

TOKYO LLC produces three products, KFC, MFC, and RFC, all made from the same material. Until now, it has used Absorption Costing System to allocate overheads to its products. The company is now considering using an Activity Based Costing System in order to improve profitability. Information for the three products for the last year is as follows:

                                                                                KFC               MFC                RFC

Production and sales volumes (units in “000”)         25                    20                   15        

Selling price per unit                                                  $20                  $30                  $15

Raw material usage (kg) per unit                               6                      7                      8

Direct labor hours per unit                                          1                      2                      3

Machine hours per unit                                               1                      0.5                   .75

Number of production runs per annum                       10                    15                    20

Number of purchase orders per annum                       10                    20                    30

Number of deliveries to retailers per annum              60                    50                    40

The price for raw materials remained constant throughout the year at $4 per kg. Similarly, the direct labor cost for the whole workforce was $15 per hour. The annual overhead costs were as follows:

OVERHEADS:                    

$

Machine set up costs               50,000

Machine running costs            80,000

Procurement costs                   30,000

Delivery costs                                     80,000

Required:

1. Calculate the cost per unit for products KFC, MFC and RFC under traditional absorption costing, using direct labor hours as the basis for apportionment.

2. Calculate the full cost per unit of each product using activity based costing.
