hello I need help in graph theory class I will get the homework in three days so I want one who can help me on it. The book which we use it is in attachment, so who can see himself is familiar with it please let me know. thanks
Stateline Shipping and Transport Company Rachel Sundusky is the manager of the South-Atlantic office of the Stateline Shipping and Transport Company. She is in the process of negotiating a new shipping contract with Polychem, a company that manufactures chemicals for industrial use. Polychem want Stateline to pick up and transport waste products from its six plants to three waste disposal sites. Rachel is very concerned about this proposed arrangement. The chemical wastes that will be hauled can be hazardous to humans and the environment if they leak. In addition, a number of towns and communities in the region where the plants are located prohibit hazardous materials from being shipped through their municipal limits. Thus, not only will the shipments have to be handled carefully and transported at reduced speeds, they will also have to traverse circuitous routes in many cases. Rachel has estimated the cost of shipping a barrel of waste from each of the six plants to each of the three waste disposal sites as shown in the following table: Waste Disposal Site Plant Whitewater Los Canos Duras Kingsport $12 $15 $17 Danville 14 9 10 Macon 13 20 11 Selma 17 16 19 Columbus 7 14 12 Allentown 22 16 18 The plants generate the following amounts of waste products each week: Plant Waste per Week (bbl) Kingsport 35 Danville 26 Macon 42 Selma 53 Columbus 29 Allentown 38 The three waste disposal sites at Whitewater, Los Canos, and Duras can accommodate a maximum of 65, 80, and 105 barrels per week respectively. In addition to shipping directly from each of the six plants to one of the three waste disposal sites, Rachel is also considering using each of the plants and waste disposal sites as intermediate shipping points. Trucks would be able to drop a load at a plant or disposal site to be picked up and carried on to the final destination by another truck, and vice versa. Stateline would not incur any handling costs because Polychem has agreed to take care of all local handling of the waste materials at the plants and the waste disposal sites. In other words, the only cost Stateline incurs is the actual transportation cost. So Rachel wants to be able to consider the possibility that it may be cheaper to drop and pick up loads at intermediate points rather than ship them directly. Rachel estimates the shipping costs per barrel between each of the six plants to be as follows: Plant Plant Kingsport Danville Macon Selma Columbus Allentown Kingsport $ __ $6 $4 $9 $7 $8 Danville 6 __ 11 10 12 7 Macon 5 11 __ 3 7 15 Selma 9 10 3 __ 3 16 Columbus 7 12 7 3 __ 14 Allentown 8 7 15 16 14 __ The estimated shipping cost per barrel between each of the three waste disposal sites is as follows: Waste Disposal Site Waste Disposal Site Whitewater Los Canos Duras Whitewater $__ $12 $10 Los Canos 12 __ 15 Duras 10 15 __ Rachel wants to determine the shipping routes that will minimize Stateline’s total cost in order to develop a contract proposal to submit to Polychem for waste disposal. She particularly wants to know if it would be cheaper to ship directly from the plants to the waste sites or if she should drop and pick up some loads at the various plants and waste sites. Develop a model to assist Rachel and solve the model to determine the optimal routes. Analyze this case, as follows: In Excel, or other suitable program, develop a model for shipping the waste directly from the 6 plants to the 3 waste disposal sites. Solve the model you developed in #1 (above) and clearly describe the results. In Excel, or other suitable program, Develop a transshipment model in which each of the plants and disposal sites can be used as intermediate points. Solve the model you developed in #3 (above) and clearly describe the results. Interpret the results and draw conclusions that address the question posed in the case problem. What are the limits of the study? Write at least one paragraph
Using a long rod that has length , you are going to lay out a square plot in which the length of each side is . Thus the area of the plot will be 2. However, you do not know the value of , so you decide to make n independent measurements X1, X2, . . . , Xn of the length. Assume that each Xi has mean (unbiased measurements) and variance s2. a. Show that is not an unbiased estimator for m2. [Hint: For any rv Y, E(Y2) V(Y) [E(Y)]2. Apply this with Y .] b. For what value of k is the estimator kS2 unbiased for 2? [Hint: Compute E( kS2).]

An armchair was purchased for a cost price of $380 and marked up to a retail price. It was then discounted by 10% to a sale price of $427.50. What is the percentage mark-up from the cost price to the sale price?
