Farmer McCoy can plant either corn or soybeans. The probabilities that the next harvest prices will go up, stay the same, or go down are .25, .30 and .45 respectively. If the prices go up, the corn crop will give a net profit of $30,000 and the soybeans will give a net profit of $10,000. If the prices remain unchanged, McCoy will have $0 profit/loss for both crops. But if the prices go down, the corn and soybeans crops will sustain losses of $35,000 and $5,000 respctively. (A) Represent McCoy's problem as a decision tree. (B) Which crop should McCoy plant?

second option

step-by-step explanation:

the measures of a triangle equal 180. use that to find x.

2x+3x+4x=180

9x=180

9x/9=180/9

x=20

now you know x, you know angle a is 40°, angle b is 60°, angle c is 80°.

because angle a is 40°, the first option doesn't work.

because angle b is 60°, the second option does work.

when you add angle a and b, you get 100°. complementary means it equals 90°, so the third option doesn't work.

when you add angle a and c, you get 120°, which is not 100.

2(2x + 3) = -4 + 2(2x + 5)

4x + 6 = -4 + 4x + 10

4x + 6 = 4x + 6

4x - 6 + 6 = 4x - 6 + 6

4x = 4x

x = x
