From past experience, the bank knows that it needs the number of tellers shown in the table below at various times of the day. Bank of Tacoma hires two types of tellers. Full-time tellers work 9am to 5pm, 5 days a week, with 1 hour off each day for lunch. The bank determines when a full-time employee takes his or her lunch hour, but each teller must go between 11am and noon, noon and 1pm, or between 1pm and 2pm. Full-time employees are paid $24 per hour, including a paid lunch hour. The bank can also hire part-time tellers. Each part-time teller works exactly three consecutive hours each day, starting at any specified hour (e.g., 10am-1pm), the same time every day of the week. A part-time teller is paid $16 per hour. To maintain adequate quality of service, the bank has decided that at all…
7. MC is looking for a location for a distribution center that provides the computers to three new retail outlets. The location of the outlets and the quantity handled at each are provided in the table below. Assuming freight rates for all outlets are the same (= 1), find the location of the distribution center by the gravity model. Show the total distribution cost at each iteration, and iterate the algorithm until the change in the total cost becomes less than 1%.
Denial of Service attacks are estimated to happen once every six months (twice a year) in a mid-size company. One such company, XYZ, estimates the cost of recovering from a single DoS attack to be $12000. The company decides to apply a number of controls to counter these attacks. With these controls, the frequency of successful DoS attacks against the company reduces to once a year and the cost of recovering from an instance becomes $8000. The cost of implementing these controls is $7,000 a year. The annual loss expectancy (ALE) without controls is $ A . The annual loss expectancy (ALE) with controls is $
COVID-19 has triggered panic buying from Ghanaians with the expectation that there will be declaration of lockdown after the closure of school across the country. Retailer are increasing the prices of their goods on the shelf based on the time it stays on the shelf. The management of “Brutus Stores” have decided on this price policy. The price of any item which is expected to sell within a week should be increased by 20%. However, if an item stays on the shelf after a week but less than or equal to two weeks the price should be increase by 15%. The price of any other item that stays on the shelf for more than two weeks should be increase by 2%. As a programmer you have been consulted to develop a program that will:a. Request for item name, current price in GHc, expected duration on shelf b. Compute the retail price of the item c. Display the results d. Explain your results

Denial of Service attacks are estimated to happen once every six months (twice a year) in a mid-size company. One such company, XYZ, estimates the cost of recovering from a single DoS attack to be $12000. The company decides to apply a number of controls to counter these attacks. With these controls, the frequency of successful DoS attacks against the company reduces to once a year and the cost of recovering from an instance becomes $8000. The cost of implementing these controls is $7,000 a year. From a purely financial point of view, is it worth for the company to implement these controls? Calculate the prior and post ALE and do a cost-benefit analysis to answer the question. In your answer make sure that you indicate what ARO, SLE and ALE are with and without controls. State clearly whether the company should implement the controls and explain why.
Denial of Service attacks are estimated to happen once every six months (twice a year) in a mid-size company. One such company, XYZ, estimates the cost of recovering from a single DoS attack to be $10,000. The company decides to apply a number of controls to counter these attacks. With these controls, the frequency of successful DoS attacks against the company reduces to once a year and the cost of recovering from an instance becomes $6,000. The cost of implementing these controls is $12,000 a year. From a purely financial point of view, is it worth for the company to implement these controls? O None of the these Yes, because the measures will save the company $2,000. ONo, because the measures will cost the company $2,000. No, because the measures will cost the company $4,000. Yes, because the measures will save the company save $14,000.
In a school, there are four teachers X1,X2,X3,X4 and five batches Y1,Y2,Y3,Y4,Y5. Given that teacher Xi is required to teach batch Yj for Pij periods, schedule a complete routine in the minimum possible number of periods. The matrix is given below: X1 X2 X3 X4 Y1 2 2 -- -- Y2 1 Y3 -- -- Y4 | 1 2 1 -- Y5 1 1 -- -- Remember there are only 3 class rooms available.
It has been observed by management that some faculty members at theuniversity demonstrate a lackadaisical attitude toward teaching. They seldom go to class yet at the end of each month they receive full salary. Management has decided that GHs 200, 300, 400, and 500 will be deducted from a faculty’s salary if he/she offends once, twice, third time and forth time respectively in a month. This means that if a faculty member offends once in a month GHs200 will be deducted, if a faculty member offends twice in a month, GHs 500 (i.e. 200+300) will be deducted, if a faculty member offends three times in a month GHs 900 (i.e. 200+300+400), will be deducted and if a faculty member offends four times in a month GHs 1,400 (i.e. 200+300+400+500). Assuming all faculty members are on a flat salary rate of GHs 2000.a. Write a program to request for the names of four faculty members and number times he/she has absented him/herself from class in a month.One of them should have absented him/herself…
A hostel warden states the following requirements for a hostel information system: Our hostel has 500 rooms and 4 messes. Currently there are 1000 students in all in 2-seated rooms. They eat in any one of he messes but can get a rebate if they inform and do not eat for at least 4 consecutive days. Besides normal menu, extra items are also given to students when they ask for it. Such extras are entered in an extras book. At the end of the month, a bill is prepared based on the normal daily rate and extras and given to student. Draw a logical DFD.

Computer science. assume you provide three orders to the robot: at time 1 maneuver to point 5, at time 3 move to point 0 and at time 6 move to point 4. Then, at that point, the robot remains at 0 until time 1, then, at that point, begins moving towards 5, overlooks the subsequent order, arrives at 5 at time 6 and quickly begins moving to 4 to execute the third order. At time 7 it arrives at 4 and stops there. You call the order I fruitful, in case there is a period second in the reach [ti,ti+1] (I. e. after you provide this order and before you give another, the two limits comprehensive; we consider tn+1=+∞) when the robot is at point xi. Count the number of fruitful orders. Note that it is conceivable that a disregarded order is fruitful. Input The principal line contains a solitary integer t (1≤t≤1000) — the number of experiments. The following lines depict the experiments. The principal line of an experiment…
