Problem 3Say you're an electrical engineer designing an electromechanical subassembly foruse in a larger aircraft system. Twelve components are to be stacked into acylindrical casing in a manner that minimizes the impact of shocks.a. If all components are different, how many different design configurationsare possible?b. If seven components are identical to one another, but the others aredifferent, how many different design configurations are possible?c.If three components are of one type and identical to each other, and four componentsare of another type and identical to each other, but the others are different, how manydifferent design configurations are possible?Problem 4

Scenario 2: In the bathroom, the homeowners wish to install subway tile around the tub. The tile will be placed above the tub on the three sides that are enclosed. The bathroom has a 9-foot ceiling height and the tub is 60 inches long by 32 inches wide by 19 inches high. The tile the homeowners have selected is 3 inches by 12 inches and is sold by the box. Each box costs $34.99 and contains 22 tiles. The supplier provides free delivery and recommends purchasing a minimum of 10% overage. Question 6: Find the total cost for the tile, including sales tax.
Rivers in North Carolina contain small concentrations of mercury that can accumulate in fish over their lifetimes. The concentration of mercury in fish tissue can be obtained by catching fish and sending samples to a lab for analysis. A study was conducted on fish from the Waccamaw and Lumber Rivers to investigate mercury levels in tissues of largemouth bass. At several stations along each river a group of fish were caught, weighed and measured; in addition a filet from each fish was sent to a lab so that the tissue concentration of mercury could be determined. In all, 171 fish were caught at 15 different research stations along the Waccamaw and Lumber Rivers. Data from fish caught at one of these stations is shown in the followinng table: length weight 1616 47.0 48.7 1862 2855 55.7 45.2 1199 1320 44.7 1225 43.8 870 38.5 1455 45.8 1220 44.0 1033 40.4 Compute the correlation between length and weight for these fish. (Assume the correlation conditions have been satisfied and round your…

Measuring the actual dimensions of a manufactured part is a classical problem in many different disciplines, particularly for quality engineers. A quality engineer is measuring the thickness of nickel plates for use in a nickel-hydrogen battery. By the way the plate is made, she can consistently identify specific locations on each plate. That is, location A is in the same spot on each plate, and location B is in the same spot on each plate. She believes that measuring thickness at location A results in a consistently thicker measure than at location B. She measured thickness, in mm, at locations A and B on the same 10 plates. Conduct an appropriate hypothesis test with 95% confidence using the critical value approach. Location A Location B 31.10 31.10 29.75 29.75 30.90 30.15 30.80 30.80 32.20 30.20 30.40 30.40 29.65 29.85 29.85 30.65 30.35 29.75 29.15 30.50
A plant food is made from three chemicals, labeled I, II, and III. In each batch of the plant food, the amounts of chemicals II and III must be in the ratio of 5to 3. The amount of nitrogen must be at least 39 kg. The percent of nitrogen in the three chemicals is 8%,4%,and 5%,respectively. If the three chemicals cost $1.02 $0.86 and $0.66 per kilogram, respectively, how much of each should be used to minimize the cost of producing at least 600 kg of the plant food?
A campaign to promote a brand of dairy products is based on the free distribution of yogurts with lemon or strawberry flavor. It is decided to distribute at least 30,000 yogurts. Every lemon yogurt needs for its elaboration 0.5 gr. of a fermentation product and each strawberry yogurt needs 0.2 gr. of that same product. It has 9 kgs. of that product for fermentation. The cost of producing a yogurt of strawberry is twice that of a lemon yogurt. How many yogurts of each type must be produced so that the cost of the campaign is minimal?.
A plant superintendent has been assigned the task of improving the joint strength of a clutch assembly. The assembly consists of two components: the clutch cup and the drive sprocket. The two components are joined together by means of a brazing operation. The plant superintendent wanted to investigate whether changing the brazing material would affect average braze strength. They decided he would braze one group with pure copper wire and braze another group with the existing copper alloy. One of the two components, the sprocket, is manufactured from powdered metal. The superintendent had observed from past studies that there was a strong relationship between the density of the sprocket and the joint strength of the assembly after brazing. The greater the porosity of the powdered metal sprocket, the more absorption of the braze material takes place, resulting in a weaker bond. They decided to use the known relationship between sprocket porosity and joint strength for setting up a…

The volume of cola of Brand A and Brand B filled into a bottle are uniformly distributed.Brand A: between 1.45 and 1.53 liters.Brand B: between 1.44 and 1.53 liters.Both brands claim that their cola contain more than 1.50 liters. Which brand should youchoose? Justify your answer.
Materials: Corn (Zea mays) kernels Rice (Oryza sativa) grains Mongo (Vigna radiata) seeds Squash (Cucurbita maxima) seeds 1-L Container Procedure: 1. Into a container put 270 corn kernels, 90 rice grains, 90 mongo seeds and 30 squash seeds. Mix them together by stirring or shaking. 2. Supposing that we are crossing two double heterozygotic pea plants (AaBb x AaBb). A=tall; a=Dwarf; B=Normal; b=wrinkled. 3. The four types of seeds represent the four possible phenotypes of the cross: Tall-normal (Corn), Tall-wrinkled (Rice), Dwarf-normal (Mongo) and Dwarfwrinkled (Squash). Note: The materials (e.g. seeds) may be changed with whatever are available at home. 4. From the container, select randomly 96 seeds and categorize them into four phenotype classes as above. The actual number of pellets per phenotype class will constitute the observed (0) frequency or actual observation. 5. The expected (E) results are not exactly equal to the actual observation. This raises the problem of how much…
