There are 3.types of well-known products, namely Day Cream (DC), Night Cream (NC) and Glow Serum(GS). It is known that the production process must go through 3 main stages, namely: Mixing(M), Pot/Bottle Filling (F) and Packaging (P). In producing each type These products requirecosts (per unit) at each stage of the production process. Cost production for each type ofproduct at each stage of production is as follows: Day Cream costs: $2 (M), $4.5 (F), $2 (P);Night Cream costs: $3 (M), $2.5 (F), $5 (P) and Glow Serum costs: $5(M), $2.5(F), $3 (P). Inaddition, party management has made a policy regarding the allocation of production costsfor each stage of the process production, namely at the Mixing stage (39%), Pot/Bottle Filling(27%), Packaging (34%) of the total cost of $2200.a. Formulate the information given above in the form of a system of linear equations andmatrixb. Using the Cramer's Rule Method, determine how many units can be produced bycompany for each type of skincare product by considering the cost allocation existingproduction.c. Which type of skincare product has the least amount of production? Give an explanation.31°C

Please give me detailed solution Thanks
There are three types of contaminants that spoils water. Organic pollutants (0), volatile solvents (V), and chlorinated compounds (C). A new analytical method to detect (D) contaminants in water is being tested. The makers of the test claim that it can detect high levels of organic pollutants with 98% accuracy, volatile solvents with 99% accuracy, and chlorinated components with 89% accuracy. If a pollutant is not present, the test does not signal. Samples are prepared for the calibration of the test and 60% of them are contaminated with organic pollutants, 27% with volatile solvents, and 13% with traces of chlorinated compounds. A test sample is selected randomly. (a) What is the probability that the test will not signal? (b) If the test signals, what is the probability that chlorinated compounds are present? (c) If the test does not signal, what is the probability that chlorinated compounds are present? Note: Use the notations in the brackets to describe the events.
The Ace Manufacturing Company has orders for three similar products. Orders (units) 2,200 Product A B C с 1 2 Machine 3 Three machines are available for the manufacturing operations. All three machines can produce all the products at the same production rate. However, due to varying defect percentages of each product on each machine, the unit costs of the products vary depending on the machine used. Machine capacities for the next week and the unit costs are shown below. A A B B C с Product 1 2 3 300 1,400 Capacity (units) 1,800 1,700 800 1 Machine 2 3 $1.00 $1.30 $1.10 $1.20 $1.40 $1.00 $0.90 $1.20 $1.20

You are the VP, Advertising for “Yo’ Mama” brand, a fashion label that caters to the young, trendy crowd with an urban, hip-hop image. While your customer base has traditionally been largely African-American, you have recognized a tremendous influx of Hispanic consumers into your market. You are preparing for next week’s annual budget meetings and you have decided to recommend an Hispanic-focused advertising campaign if the average monthly per store sales to Hispanic customers are at least the same as the average monthly per store sales to African-American customers in a sample of typical stores (sales data given below). Using an alpha of .05 and the 5-step hypothesis testing process, what will you recommend? Hint: Think about how many data points you actually have.
1. In an effort to determine whether a new type of fertilizer is more effective than the type currently in use, researchers took twelve 2-acre plots of land scattered throughout the county. Each plot was divided into two equal-sized subplots, one of which was treated with the current fertilizer and the other of which was treated with the new fertilizer. Wheat was planted, and the crop yields measured. These data are in the table below New Fertilizer current Fertilizer 39 36 75 68 44 77 87 85 96 90 85 84 65 60 a. Can we conclude at the 5% significance level that the new fertilizer is more effective than the current one?, That is to say , test the hypothesis Но: и — и, — 0 versus Ha: д — и, >0 for a %3D.05. b. Estimate with 95% confidence the difference in mean crop yields between the two fertilizers.
A shoe wholesaler wants to optimize its shipment of shoes to its client retailers. To minimize their turnover time and avoid building up stocks that add costs, the wholesaler wants to know if weather conditions are important in determining the type of shoe demanded. Specifically, she / he would like to know if high temperatures affect the sale of closed, rubber-heeled walking shoes. He / she has the relevant data showing the temperature recorded at the location of its retail shops, as well as their record of sales of these walking shoes, during each day of the past year. What type of analysis should he / she conduct? What variables should be considered? Explain.
