A company manufactures two types of trucks. Each truck must go through the painting shop and the assembly shop. If the painting shop were completely devoted to painting type 1 trucks, 800 per day could be painted, whereas if the painting shop were completely devoted to painting type 2 trucks, 700 per day could be painted. If the assembly shop were completely devoted to assembling truck 1 engines, 1500 per day could be assembled, whereas if the assembly shop were completely devoted to assembling truck 2 engines, 1200 per day could be assembled. It is possible, however, to paint both types of trucks in the painting shop. Similarly, it is possible to assemble both types in the assembly shop. Each type 1 truck contributes $1000 to profit; each type 2 truck contributes $1500. Use Solver to maximize the company’s profit

Truckco manufactures two types of trucks: 1 and 2. Each truck must go through the painting shop and assembly shop. If the painting shop were completely devoted to painting Type 1 trucks, then 800 per day could be painted; if the painting shop were completely devoted to painting Type 2 trucks, then 700 per day could be painted. If the assembly shop were completely devoted to assembling truck 1 engines, then 1,500 per day could be assembled; if the assembly shop were completely devoted to assembling truck 2 engines, then 1,200 per day could be assembled. Each Type 1 truck contributes $300 to profit; each Type 2 truck contributes $500. How much capacity in percent does a single truck of each type uses at each shop?
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 farmer in Georgia has a 100-acre farm on which to plant watermelons and cantaloupes. Every acre planted with watermelons requires 50 gallons of water per day and must be prepared for planting with 20 pounds of fertilizer. Every acre planted with cantaloupes requires 75 gallons of water per day and must be prepared for planting with 15 pounds of fertilizer. The farmer estimates that it will take 2 hours of labor to harvest each acre planted with watermelons and 2.5 hours to harvest each acre planted with cantaloupes. He believes that watermelons will sell for about $3 each, and cantaloupes will sell for about $1 each. Every acre planted with watermelons is expected to yield 90 salable units. Every acre planted with cantaloupes is expected to yield 300 salable units. The farmer can pump about 6,000 gallons of water per day for irrigation purposes from a shallow well. He can buy as much fertilizer as he needs at a cost of $10 per 50-pound bag. Finally, the farmer can hire laborers to…
It has been observed by management that some faculty member at the university demonstrates a lackadaisical attitude toward work. 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 GHs 200 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 2500.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 private university, students can enrol for at least 1 to a maximum of 5 subjects in a semester. Subjects that are to be offered in that particular semester will be assigned to a class. One class should have at least 5 students and up to a maximum of 40 students. Multiple classes for a subject can be created if the students number enrolled for the subject is large. A subject might not be offered on that semester depending on the needs. A lecturer can be assigned to zero and up to a maximum of 4 classes on that particular semester. Draw the class diagram to represent the above scenario. Each entity should have at least 1 attribute as its identity. Provide the relevant associations between these entities and include the multiplicities.
An Uni has n students who are regular competitive programmers. According to the ACM ICPC rules, each person can participate in the regional championship at most 5 times. The head of the Uni ACM Chapter is recently gathering teams to participate in this championship. Each team must consist of exactly three people, at that, any person cannot be a member of two or more teams. What maximum number of teams can the head make if he wants each team to participate in the world championship with the same members at least k times? The first line of input contains two integers, n and k. The next line contains n integers: y1, y2, ..., yn (0 ≤ yi ≤ 5), where yi shows the number of times the i-thperson participated in the ACM ICPC Regional . Write a python program that prints how many teams can be formed according to the above problem statement.

A materials engineer wants to study the effects of two different processes for sintering copper (aprocess by which copper powder coalesces into a solid but porous copper) on two different typesof copper powders. From each type of copper powder, she randomly selects two samples andthen randomly assigns one of the two sintering processes to each sample by the flip of a coin.The response of interest measured is the porosity of the resulting copper. Explain what type ofstudy this is and why.
A library must build shelving to shelve 200 4-inch high books, 150 8-inch high books, 300 10-inch high books and 180 12-inch high books. Each book is 0.5 inch thick. The library has several ways to store the books. For example, an 8-inch high shelf may be built to store all books of height less than or equal to 8 inches, and a 12-inch high shelf may be built for the 12-inch books. Alternatively, a 12-inch high shelf might be built to store all books. The library believes it costs $2,300 to build a shelf and that a cost of $5 per square inch is incurred for book storage. (Assume that the area required to store a book is given by height of storage area times book’s thickness.) Formulate and solve a shortest-path problem that could be used to help the library determine how to shelve the books at minimum cost. (Hint: Have nodes 0, 4, 8, 10 and 12, with cij being the total cost of shelving all books of height >i and ≤ j on a single shelf.)
The city of Bloomington is about to build a new watertreatment plant. Once the plant is designed (D), we canselect the site (S), the building contractor (C), and theoperating personnel (P). Once the site is selected, we canerect the building (B). We can order the water treatmentmachine (W) and prepare the operations manual (M) onlyafter the contractor is selected. We can begin training (T)the operators when both the operations manual and operatingpersonnel selection are completed. When the treatment plantand the building are finished, we can install the treatmentmachine (I). Once the treatment machine is installed andoperators are trained, we can obtain an operating license(L). The estimated mean and standard deviation of the time(in months) needed to complete each activity are given inTable 8. Use simulation to estimate the probability that theproject will be completed in (a) under 50 days and (b) morethan 55 days. Also estimate the probabilities that B, I, andT are critical…

A large paper manufacturing company, the Quality Paper Corporation, has 10 paper mills from which it needs to supply 1,000 customers. It uses three alternative types of machines and four types of raw materials to make five different types of paper. Therefore, the company needs to develop a detailed production distribution plan on a monthly basis, with an objective of minimizing the total cost of producing and distributing the paper during the month. Specifically, it is necessary to determine jointly the amount of each type of paper to be made at each paper mill on each type of machine and the amount of each type of paper to be shipped from each paper millto each customer. The relevant data can be expressed symbolically as follows:Djk = number of units of paper type k demanded by customer j,rklm = number of units of raw material m needed to produce 1 unit of paper type k on machine type l,Rim = number of units of raw material m available at paper mill i,ckl = number of capacity units of…
