b) Tshepile Wool Company (DWC) operates a large farm on which sheep are raised. Thefarm manager determined that for the sheep to grow in the desired fashion, they need atleast minimum amounts of four nutrients (the nutrients are nontoxic so the sheep canconsume more than the minimum without harm). The manager is considering threedifferent grains to feed the sheep. Table 1 lists the number of units of each nutrient ineach kilogram of grain, the minimum daily requirements of each nutrient for each sheep,and the cost of each grain.Table 1: Tshepile Wool DataMinimum DailyRequirement(units)110Grain13Nutrient A203070Nutrient B101018Nutrient CNutrient D5030901462,510Cost (R/g)413696The manager believes that as long as a sheep receives the minimum daily amount ofeach nutrient, it will be healthy and produce a standard amount of wool. The managerwants to raise the sheep at minimum cost. Formulate the above problem as an LPproblem.

Consider the following approach: At an animal shelter, three types of food are provided for three species of freshwater turtles. Each turtle of species 1 consumes an average of 1 unit of food A, 1 of B and 2 of C per week. Species 2 consumes 1 unit of food A, 4 of B and 5 of C. Species 3 requires 2 units of food A 1 of B and 5 of C. It is known that the shelter can supply weekly 99 units of food A, 181 units B and 320 units of C. If we assume that the turtles consume all the food, indicate the number of turtles of each species that the shelter can maintain. a. Establishes the system of linear equations that models the approach b. Solve the system of linear equations using the Gauss-Jordan method
Parent W requires one of component B and two of component C. Both B and Care run on work center 10. Setup time for B is 2 hours, and run time is 0.1 hour perpiece. For component C, setup time is 2 hours, and run time is 0.15 hour per piece. Ifthe rated capacity of the work center is 80 hours, how many Ws should be producedin a week?
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.

Freight Crate Inc. produces small, medium, and large shipping crates used by a variety of clients and companies. Each month, Freight Crate produces and ships it's own (empty) containers out to its distributor to be sold. Data on the shipping containers' weights and costs are given in the table below: Small Medium Large Weight (lbs per container) 20 44 80 Cost to Produce (per container) $20 $40 $100 A shipment of containers must adhere to an imposed weight limit of 9,664 lbs. Furthermore, pre- vious sales data suggest that Freight Crate should produce twice as many medium containers as large containers. The company hopes to determine the total of each type of container to produce on a monthly shipping budget of $10,300. Define x, y, and z to be the total number of small, medium, and large containers produced montly, respectively.
The general perception is that the manufacturer of the product can reduce the cost required to manufacture a single product by increasing the number of manufactured products. The following material lists the quantities of products produced by one manufacturer and the corresponding costs per product.

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?.
Tim Smunt has been asked to evaluate two machines. After some investigation, he determines that they have the costs shown in the following table: He is told to assume that: 1. The life of each machine is 3 years. Machine A Machine B Original Cost Labor per year $15,000 $20,000 $2,200 $4,000 Maintenance per year Salvage value $4,600 $1,000 $2,400 $7,500 2. The company thinks it knows how to make 8% on investments no more risky than this one. 3. Labor and maintenance are paid at the end of the year. • The NPV for Machine A: The NPV for Machine B: Using the net present value as the basis of comparing the machines, Tim should recommend:
A freshly brewed shot of espresso has three distinct components: the heart, body, and crema. The separation of these three components typically lasts only 10 to 20 seconds. To use the espresso shot in making a latte, a cappuccino, or another drink, the shot must be poured into the beverage during the separation of the heart, body, and crema. If the shot is used after the separation occurs, the drink becomes excessively bitter and acidic, ruining the final drink. Thus, a longer separation time allows the drink-maker more time to pour the shot and ensure that the beverage will meet expectations. An employee at a coffee shop hypothesized that the harder the espresso grounds were tamped down into the portafilter before brewing, the longer the separation time would be. An experiment using 24 observations was conducted to test this relationship. The independent variable Tamp measures the distance, in inches, between the espresso grounds and the top of the portafilter (i.e., the harder the…
In 1898 the United States and Spain fought a war over the U.S. intervention in the Cuban War of Independence. At that time, the U.S. military was concerned about the nutrition of its recruits. Many did not have a sufficient number of teeth to chew the food provided to soldiers. AS a result, it was likely that they would be undernourished and unable to fulfill their duties as soldiers. The requirements at that time 1 specified that a recruit must have "at least four sound double teeth, one above and one below on each side of the mouth, and so opposed" so that they could chew food. Of the 58,952 recruits who were under the age 1 of 20, 68 were rejected for this reason. For the 43,786 recruits who were 40 or over, 3801 were rejected.2l > Find a 99% confidence interval for the difference in the proportions. C Use a significance test to compare the proportions.

The dams in and around Cape Town form part of the Western Cape Water Supply System, which is an integrated and collectively managed system of dams, pump stations, pipelines, and tunnels. In addition to servicing Cape Town, the system supplies water to towns in the Overberg, Boland, West Coast, and Swartland areas, and provides irrigation water for agriculture. The change in depth of the Steenbras dam from one day to the next, measured (in feet) at in Cape Town, is a random variable Y with the following density function: f(y) = 2 < y< 4, elsewhere. 2.4.1. Define the random variable Y. 2.4.2 State what type of distribution does Y follow and why: 2.4.3. Find E (Y) and interpret your answer.
