A store has two types of animal feed available. Type A contains 2 pounds of oats and 5 pounds of corn per bag. Type B contains 7 pounds of oats and 3 poundsof corn per bag. A farmer buys both types and combines them so that the resulting mixture has at least 70 pounds of oats and at least 75 pounds of corn. Thestore only has 30 bags of type A feed and 20 bags of type B feed in stock. Let x be the number of type A bags purchased. Let y be the number of type B bagspurchased. Shade the region corresponding to all values of x and y that satisfy these requirements.-1050--4030-2010--10-1020304050);)

This time, our immune system is the best defense. With this, a Melagail wishes to mix two types of foods in such a way that vitamin contents of the mixture contain at least 8 units of vitamin A and 10 units of vitamin C. Food A contains 2 units/kg of vitamin A and 1 unit/kg of vitamin C. Food B contains 1 unit/kg of vitamin A and 2 units/kg of vitamin C. It costs ₱50 per kg to purchase Food A and ₱70 per kg to purchase Food B. Formulate this problem as a linear programming problem to minimize the cost of such a mixture and find the optimal solution graphically.

A manufacturer of projection TVs must ship a total of at least 1000 TVs to its two central warehouses, x to the first warehouse and y to the second warehouse. Each warehouse can hold a maximum of 750 TVs. The first warehouse already has 150 TVs on hand, whereas the second has 50 TVs on hand. It costs $6 to ship a TV to the first warehouse, and it costs $18 to ship a TV to the second warehouse. How many TVs should be shipped to each warehouse to minimize cost?

A researcher believed that the number of rental cars in service by a car rental company would have an impact on the total annual revenue for that car rental company. Five small car rental companies were surveyed, with the number of Cars in service recorded in units of 1000 (so if a car rental company had 54000 cars in service, a 54 would be recorded) and Annual Revenue measured in millions of dollars (so an Annual Revenue of $10,000,000 would be recorded as 10). The data follows: Cars (1,000s) Annual Revenue ($ millions)11.5 118 10.0 135 9.0 100 5.5 37 3.3 32 Part of the Excel-generated Simple Linear Regression output is provided below: ANOVA df SS MS F Significance F Regression 1 7891.863897 7891.863897 22.91180151 0.017339231 Residual 3 1033.336103 344.4453677 Total 4 8925.2 Coefficients Standard Error t Stat P-value Intercept -19.12490108 23.1658578…
live 9 (rectangular) blocks from Tech, and I walk each morning. The trip is 3 blocks north and 6 blocks west; and I have to follow the streets, so I cannot cut diagonally. At each intersection, I must choose whether to walk north or walk west. Thus, I must make 9 choices of which to take, but of course must go north 3 times and west 6 times. How many possible complete trips to Tech are there?
Suppose that weights of males in my family are N(250,24) where 250 and 24 are in pounds. I weigh 230 pounds. The percentage of males in my family that weigh more than me and less than my brother is 35%. How much does my brother weigh?
