Hot Water (HW) is asmall start-up company that sells spas. HW does not carry any stock. A few spas areset up in a simple warehouse so customers can see some of the models available, butany products sold must be ordered at the time of the sale.• HW can get spas from several different manufacturers.• Each manufacturer produces one or more different brands of spas.• Each and every brand is produced by only one manufacturer.• Every brand has one or more models.• Every model is produced as part of a brand. For example, Iguana Bay Spas is amanufacturer that produces Big Blue Iguana spas, a premium-level brand, andLazy Lizard spas, an entry-level brand. The Big Blue Iguana brand offers severalmodels, including the BBI-6, an 81-jet spa with two 6-hp motors, and the BBI-10,a 102-jet spa with three 6-hp motors.• Every manufacturer is….

- An electronics mega store is getting opened in "India". Under the same cap of Indian Mega store other two mega stores for North and South are getting opened. Under cap of North Store, two more sub-stores are getting opened. In this manner, total of 15 stores are opened which each having their own regions to cater to. At a particular time a store can handle at the most two sub stores. A particular store makes an earning of "X" amount for a given month. Ultimately at the end of month, all sub store submit their collected amount to their managing store. An model is needed to add more store, and print their monthly revenue. What do you think will be good data structure and how. What other facility can you provide to it. Implement the given model. using c languageConsider online library system where library administrator is able to see all the books transaction made by students and staff. Draw the class diagram (proper relations between different classes) and Use case diagram for the above scenario.Three persons P1, P2, and P3 were invited by their friend F to make some smørbrød (sandwich made of bread, eggs, and tomato) together. To make a portion of smørbrød, three ingredients are needed: a slice of bread, a slice of tomato, and a slice of an egg. Each of these persons P1, P2, P3 has only one type of each of the ingredients: person P1 has slices of bread person P2 has slices of tomato; person P3 has slices of egg. We assume that persons P1, P2, and P3 each has an unlimited supply of these ingredients (i.e., slices of bread, slices of tomato, slices of egg), respectively. Their friend F, who invited them, also has an unlimited supply of all the ingredients. Here is what happens: the host F puts two random ingredients on the table. Then the invited person who has the third ingredient picks up these other two ingredients, and makes the smørbrød (i.e., takes a slice of bread, puts on it a slice of tomato, and puts on top a slice of egg), and then eats the smørbrød. The host of…
- 1)Modeling: Make a CDM from the following scenario: * A retail company wants to manage their sales activity. We have the following information- The date of sale, with the possibility of rolling up to the week, month, quarter and year- the store where the sale was made: store name, brand, address, city, department and region. - The employee associated with each sale: surname, first name, date of birth, social security number. Each employee is associated with a store.the customer who purchased the product surname, first name, date of birth, address. The product sold product name, d - iption, category, unit price. The order: quantity sold, amount of turnover, amount of margin. A transaction can consist of one or more orders. The indicators (quantity, turnover, margin) can be negative if it is a reimbursement. 2) In your MCD above, what are the dimension tables? * 3)In your MCD above, what are the fact tables?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.Telemedicine is the ability to provide medical assistance from a distance using telecommunication. For this example, imagine that a platoon of soldiers might be out in the battlefield. While a medic might be with them, he/she cannot constantly monitor each soldier’s vital signs, but if various sensors were sewn into soldier uniforms, vital statistics could be monitored from a distance by a doctor at headquarters. That doctor may be able to identify a medical problem for one of the soldiers and relay that information and instructions for care back to a medic in the area. The doctor at headquarters should be able to select a given soldier and see that soldier’s vital signs on a portable computer device (e.g., iPad). Perhaps the medic in the field might even have a video camera so that the doctor may be able to view a wound. Design the interface that the HQ doctor would see. Using the display design principles design an interface mockup using graphics, photos, and/or text to show what…
- The following paragraph describes a pit stop in an FI race. Draw a process map of this activity that describes the roles of the different people and how they interact (that is a process map with "swim lanes"). An FI Pit Stop A) The pit stop starts by inflating the new tyres with nitrogen. Nitrogen is used instead of air as it copes with the temperature changes better. B) Then the tyres are placed in a heating blanket that will bring the tyres up to an optimal temperature. At this temperature they are very sticky and hold the car on the road very well. C) During the race, the pit stop activities start a few minutes before, the tyres are removed from their heating blanket, tools are manned, the pit crew take their positions.A city operates a set of tram lines. There are a number of stops for each tram line. For each tram line exactly one stop is the origin of the tram line and exactly one stop is the destination of the tram line. A terminus of a tram line is a stop that is either origin or destination of the tram line. 1)Model the tram system we just described in Alloy. Add signature facts when needed. Express each of the following constraints by an Alloy predicate: No two tram lines have the same stops Every tram stop is served by at least one tram line No two tram lines share the same terminus. 2) Write the following three functions: A function that returns all the tram lines serving a given stop A function that returns for two stops the set of tram lines serving both stops A function that returns, for two given tram lines, the set of stops that are served by both tram lines Add the notion of route to the above model: a route is defined for a tram line and consists of the (ordered) sequence of stops…Correct answer will be upvoted else downvoted. Computer science. You are permitted to alter the marks through the accompanying activity: Pick two particular integers I and j among 1 and n. Trade the marks of focuses I and j, lastly Draw the section between focuses I and j. A grouping of tasks is legitimate if in the wake of applying every one of the activities in the succession all together, the k-th point winds up having the name k for all k among 1 and n comprehensive, and the drawn sections don't meet each other inside. Officially, assuming two of the portions cross, they should do as such at a typical endpoint of the two sections. Specifically, all drawn portions should be unmistakable. Track down any legitimate arrangement of activities, or say that none exist. Input The main line contains an integer n (3≤n≤2000) — the number of focuses. The I-th of the accompanying n lines contains three integers xi, yi, man-made intelligence (−106≤xi,yi≤106,…
