A large apple farm distributes their apples in boxes that they can source from any one of a number of nearby box manufacturers. Each box manufacturer makes only one box type that holds a specific number of apples - so a box from one manufacturer might hold 24 apples, while a box from another might hold 13. The apple farm can only choose one box supplier each year (a decision they make each year based on price), but they can then order an unlimited number of boxes of that type. The farm likes to be prepared, and creates large batches of apples to pack before the decision about which box type to use has been made. The farm also likes to limit waste, and tries to set the number of apples in these large batches such that they can fill an integer number of boxes perfectly with no apples left over. In creating these batches, although the farm doesn't yet know the exact capacity of the boxes they will buy, they know a list of possible values the box capacity will take. For example, if the…
A service has five tasks, performed in sequence. In the instance when there is more than one worker assigned to a task, each worker performs the entire task and they both can be working on different “items” at the same time. What is the throughput time (assuming no wait time)? Please provide details as to how this is calculated. Task Task time per worker Number of workers 1 2 minutes 1 2 6 minutes 1 3 14 minutes 2 4 4 minutes 1 5 15 minutes 3
A job scheduler gets work requests with a priority of execution attached to it, in the following sequence. The higher the priority value, the more important task execution.Work ID: 464 212 110 840 976 3433 2 3 1 2 2 Priority: 3 2 3 1 2 2Create a treap for the jobs that are set to run. What will the treap look like after the highest priority jobs have finished execution and thus left the treap?
Jeddah Municipality has decided to build a network of national hospitals to treat infectiousdiseases. A special task force is constituted which is tasked to investigate possible locations forthese new hospitals. The task force has done its job and come back with a list of potential sites.Each of these hospitals has an associated cost and will provide coverage to some number ofnearby districts within Jeddah. We can represent each potential hospital site as having: a name(string), cost to build the hospital (int) and a set of districts to be covered (Set of strings).Jeddah Municipality is interested in providing health care to all, but they do not have funds tobuild an unlimited number of hospitals. The goal is to provide coverage to as many districts aspossible using the available funds. For example, suppose Jeddah Municipality has the followingdistricts:Al-Aziziya, Ar-Rihab, Mosharafa, Al-Faysaliya, Bani Malik, An-Naseem, Al-Balad, Al-Salam, AlMakarona, As-Salmiya, Al-Gozain,…

In addition to being a Computer Scientist, you have a (side-hustle) business where you sell flower bouquets.Each of your flower bouquets consists of a certain number of red roses, with a minimum of 1 and a maximum of 6. This is the profit you make from each of your bouquets, which is a function of the number of red roses in that bouquet. You have 6 roses with you, and now you need to decide what bouquets to make in order to maximize your profit. I have presented this data as a set of tuples below. (Roses, Prices) = {(1,$3),(2,$5), (3, $9), (4,$13), (5,$14), (6,$18)} For example, if you make two 2-rose bouquets and two 1-rose bouquets (2+2+1+1=6), then your profit is 5+5+3+3=16 dollars. Note- for this problem you can have multiple rose bouquets in each category. However, if you make a 5-rose bouquet and a 1-rose bouquet (5+1=6), then your profit is 14+3=17 dollars. Determine the maximum profit you can make.
Santa is worried about his employee relations, since christmas preparations have led to a lot of overtime. To make sure all the elves are happy, he wants to recruit some of them as complaint officers, with weekly meetings to report any complaints or worries to him. His worker elves W are pretty busy already, so Santa wants to task no more than k elves with this additional workload. Still, Santa wants to make sure that for as many elves e e W as possible, at least one of his friends (whose identities he knows) is a complaint officer. 1. Give an intuitive greedy algorithm that outputs k elves that will serve as compliant officers. 2. Prove that for large numbers of k the algorithm approximates a solution with ratio no more than (1 - ).
Last year the Diamond Manufacturing Company purchased over $10 million worth of of- fice equipment under its “special ordering” system, with individual orders ranging from $5,000 to $30,000. Special orders are for low-volume items that have been included in a department manager’s budget. The budget, which limits the types and dollar amounts of office equipment a department head can requisition, is approved at the beginning of the year by the board of directors. The special ordering system functions as follows. c. Describe how the control procedures you recommended in part b should be modified if Diamond reengineered its expenditure cycle activities to make maximum use of current IT (e.g., EDI, EFT, bar-code scanning, and electronic forms in place of paper documents).d. Draw a BPMN diagram that depicts Diamond’s reengineered expenditure cycle.

The below excerpt describes the reimbursement policy for tour-guide expenses of Holiday tours. "There are three reimbursement situations. For single destination tours, the tour-guide can only claim travel mileage for 30 cents per KM. For one-day trip, tour guides could claim mileage of 30 cents per KM and food expenses but depending on the time that the tour starts and ends. To claim expenses for breakfast, the tour should start latest by 7:00 AM and tour ends at 4:00 PM or later. To claim expenses for lunch, tour starts latest by 10:00 AM and ends at 4:00 PM or later. To claim expenses for dinner, tour starts at latest by 10:00 AM and ends at 7:00 PM or later. For trips that involves overnight stay, tour-guides can claim full expenses for lodging and transportation. Food expenses can also be claimed but also depending on the same policy as the One day trip" 1. Use structured English to describe the reimbursement policies. 2. Draw a decision tree to describe the reimbursement policy 3.…
Before 350 companies are awarded ISO 9002, few officers are assigned to check all the items manufactured by the companies. After the inspection, the officers prepared a report as follows: 8. x companies had non-defective(N) items only, y companies had partially defective(P) items only, 26 companies had defective (D) items only, 60 companies had non-defective and partially defective items 45 companies had non-defective and defective items 75 companies had defective and partially defective items 15 companies had non-partially and defective items Represent the above information in a Venn diagram. (i) If the number of company that had non-defective items is more by 10 than those companies that had partially defective items, derive a pair of simultaneous equations in x and y. (ii) Solve the equations in (i). (iii) Find the number of companies that had non-defective or defective items.
