Person A: I don't think children should run into the busy streets.


Person B: I think that it would be foolish to lock up children all day with no fresh air.

Person B uses flawed argument. What type of fallacy is it? Give a reason.

Find the chromatic number of the graph below:

Write the constraint inequalities for this situation: Kim and Lynn produce pottery vases and bowls. A vase requires 35 oz. of clay and 5 oz. of glaze. A bowl requires 20 oz. of clay and 10 oz. of glaze. There are 500 oz. of clay available and 200 oz. of glaze available. The profit on one vase is $5 and the profit on one bowl is $4.

Graph the constraint inequalities for a linear programming problem shown below. Which feasible region shown is correct?

The graph of the feasible region for a mixture problem is shown below. Find the point that maximizes the profit function P = 2x + y.

Find an initial solution using the Northwest Corner Rule and compute its total transportation cost.

Transport as many units of bread as possible through (Bakery1,Store3) and compute the improvement in total transportation cost. Adjust the numbers in the fields as necessary.

Staw Man: why does kids not running on the street im ply they have to be kept indoors?
Limited Choice: kids can be out, just not on the street.

A

Transportation Cost: 3*3+2*1+3*5+3*4 = 38

Change in Transportation cost:      2*(2 - 5 + 1 - 4) = -12 , that's an improvement.
