A contractor is considering a sale that promises a profit of ​$35 comma 000 with a probability of 0.7 or a loss​ (due to bad​ we
Nady [450]

Answer:

$19,100

Step-by-step explanation:

The expected profit would be the probability of profit multiplied by the profit and the sum of probability of loss multiiplied by the loss.

So, we can say:

E(p) = P(p)*P + P(L)*L

Where

E(p) is expected profit

P(p) is probabilty of profit (0.7)

P is the profit (35,000)

P(L) is probability of loss (0.3)

L is the loss (-18,000)

Substituting these values, we get:

E(p) = P(p)*P + P(L)*L

E(p) = (0.7)(35,000) + (0.3)(-18,000)

E(p) = 19,100

The expected profit is $19,100

Solve the system by substitution 5x+y=-10. 4x-7y=-8
storchak [24]

Answer:

x = -2 and y = 0

Step-by-step explanation:

5x + y = -10

4x - 7y = -8

Rearrange the first equation to equal y.

5x + y = -10

y = -10 - 5x

Replace y in the second equation with the first equation.

4x - 7y = -8

4x - 7(-10 - 5x) = -8

4x - (-70 -35x) = -8

4x + 70 + 35x = -8

Rearrange the equation to find x.

4x + 35x = -8 - 70

39x = -78

x = -2

Now that you know x, use the rearranged first equation to find y.

y = -10 - 5x

y = -10 - 5(-2)

y = -10 + 10

y = 0
