Solve linear programming problem using Solver tool and Graphical process.
A farmer in Iowa owns 45 acres of land. He is going to plant each acre with wheat or corn. Each acre planted with wheat yields $200 profit, requires 3 workers, and requires 2 tons of fertilizer; each with corn yields $300 profit, requires 2 workers, and requires 4 tons of fertilizer. One hundred workers and 120 tons of fertilizer are available.
a. Use Solver to help the farmer make the most of the profit from his land.
b. Confirm graphically that the solution from part (a) maximizes the farmer's profit from his land.
It has been claimed that women live longer than men; however, men tend to be older than their wives. Ages of sixteen husbands and wives from England were obtained. These data should be analyzed with a
