- Just do d and e optionsarrow_forwardA farmer has recently acquired a 110 hectares piece of land. He has decided to grow Wheat and barley on that land. Due to the quality of the sun and the region's excellent climate, the entire production of Wheat and Barley can be sold. He wants to know how to plant each variety in the 110 hectares, given the costs, net profits and labor requirements according to the data shown below: Variety Cost (Price/Hec) Net Profit (Price/Hec) Man-days/Hec Wheat 100 50 10 Barley 200 120 30 The farmer has a budget of US$10,000 and an availability of 1,200 man-days during the planning horizon. In addition, the farmer would like to get a profit of at least $3000. Generate the mathematical model for the optimal usage of land area to produce wheat and barley. Using graphical method to optimize land usage, how many hectares are to be used for wheat and barley.arrow_forwardScenario 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.arrow_forward
- Animal population densities are important to those who manage wildlife. This is particularly true when animals pose risks to humans. Managing the population of grizzly bears in the surrounds of a park is one example. Let's say that the park in question is 2,962 square miles. Additionally, the bears roam a surrounding area that is 60% as large as the park. Although their territories overlap considerably, let's say each bear needs at least 15 square miles to himself/herself to call home. If there are about 2 adult female bears for every 1 adult male bear, then approximately how many female bears can be supported in and around the park? Remember: There are 315 bears in total in the park.arrow_forwardWhat are som real life examples related to system of equations...arrow_forwardThere are many real-life problems like the traveling salesperson problem.For example, the telephone company must decide on the most efficient route for a worker to collect the money from public telephones.

- The Reception of the Laweh Graduate School receives external telephone calls. Due to certain difficulties, it is only one person who is taking care of the Reception Area. Ms. Jennifer, the receptionist wants to vacate her post for lunch between the hours of 1 and 2 pm. She knows that, the average number of phone calls received on the switchboard per hour is 2. However, what she does not know is the number of calls she will miss during the period. You can help her to determine the probability that during that one particular break hour: (i) No call will be received on the switchboard (ii) At least three calls will be received on the switchboardarrow_forwardI'm a bit confused on how to "discuss the relationship" for part a and " Interpret" for part c.

One question asks people about 'the number of times they worry about money per day. The researchers are curious about whether or not this varies depending on where people live, i.e, in either an urban or rural environment. Below is some data for 10 respondents. Choose the appropriate type of t-test to examine whether the mean number of times people worry varies by their type of environment - urban or rural. When you have calculated the t-statistic, use your table of critical values of t, with the p value criteria (alpha) of .05 to conduct your hypothesis test, State your conclusion in a complete sentence(s), and in the context of the research question. **You can use the following information to…arrow_forward
