My NotesAsk Your Teacher Solve this problem using the simplex method. (Answers should be accurate to at least 2 decimal places.) A farmer has a 320 acre farm on which she plants two crops: corn and soybeans. For each acre of corn planted, her expenses are $50 and for each acre of soybeans planted, her expenses are $100. Each acre of corn requires 60 bushels of storage and yields a profit of $60; each acre of soybeans requires 40 bushels of storage and yields a profit of $90. The total amount of storage space available is 19200 bushels and the farmer has only $20000 on hand. (a) How many acres of each crop should she plant in order to maximize her profit?
(b) What will her profit be if she follows this strategy? 20. –/4 points
My NotesAsk Your Teacher You wish to create a 4 digit number. The only digits available are 2,5, and 7, but you can use multiple copies of these digits if you wish. How many different 4 digit numbers can be formed if the only digits available for use are 2,5, and 7? 21. –/6 points My NotesAsk Your Teacher Here is some information about 3 sets.
A B C contains 3 elements A B C c contains 3 elements A B c C contains 10 elements A c B C contains 2 elements A B c C c contains 5 elements A c B C c contains 4 elements A c B c C contains 2 elements A c B c C c contains 5 elements Put this information into a Venn Diagram and answer the questions below. How many elements are there in the set A c ? How many elements are there in the set A c ∪ B? How many elements are there in the set A ∪ (B c C)? 22. –/10 points My NotesAsk Your Teacher Here are the results of a survey of magazine readers. A total of 104 people were included in the survey. 27 read Sports Illustrated 37 read Esquire 36 read Popular Mechanics 13 read Sports Illustrated and Esquire 11 read Sports Illustrated and Popular Mechanics 8 read all three magazines. 34 don't read any of the magazines Put this information into a Venn diagram and answer the questions below. (Hint: It's easy to fill in the numbers for 5 of the 8 regions in the Venn diagram. Since you know the total number of people in the survey, you can determine the sum of the 3 missing numbers. Since you know how many read Esquire, you can figure what the sum of 2 of the 3 missing numbers add up to. That gives you enough information to finish filling in a number in all regions of the Venn diagram.) How many read ONLY Sports Illustrated? How many read ONLY Sports Illustrated and Esquire? How many read exactly 2 of the 3 magazines?
