1.The graph of the feasible region is:

g= 3x + 4y

Points are:

3x+y= 60

4x+10y=280

x+y= 40

-Find the corners of the feasible region. (order your answer from smallest to largest x, and from smallest to largest y.)

(x,y)=

(x,y)=

(x,y)=

(x,y)=

- find the maximum and minimum of the given objective function

Maximum g= _____

Minimum g= ______

2. Use a probability tree or baye's formula to find the probability

There are 3 urns containing coins, Urn 1 contains 5 gold coins, urn 2 contains 3 gold coins and 3 silver coins, and urn 3 contains 4 silver coins. An urn is selected and a coin is drawn from the urn. If the coin is gold, what is the probability that urn 1 was selected?

3. In(x+2)+In(x)=In(x+30)
