poizon [28]

Answer:

The EMV of this project is -17,500

Step-by-step explanation:

The EMV of the project is the Expected Money Value of the Project.

This value is given by the sum of each expected earning/cost multiplied by each probability.

So, in our problem

EMV = P_{1} + P_{2} + P_{3} + P_{4}

The problem states that there is a 25% chance of Snowmaggedon which will delay the project at a cost of $35,000. Since this is a cost, P_{1} is negative.

P_{1} = 0.25*(-35,000) = -8,750

There is a 10% chance of cost of construction materials dropping saving the project $70,000. A saving is an earning, so P_{2} is positive

P_{2} = 0.10*70,000 = 7,000

There is a 10% probability a labor strike will occur delaying the schedule with a cost of $40,000.

P_{3} = 0.10*(-40,000) = -4,000

There is a 80% chance of new regulations mandated calling for higher inspection standards which will cost an additional $15,000 to mitigate

P_{4} = 0.80*(-15,000) = -12,000

EMV = P_{1} + P_{2} + P_{3} + P_{4} = -8,750 + 7,000 - 4,000 - 12,000 = -17,500

The EMV of this project is -17,500

\frac{2}{3x - 2c} + ( - ( \frac{3}{2x - 3c} )) = \frac{7}{2c}

\frac{2}{3x - 2c} - \frac{3}{3x - 2c} = \frac{7}{2c}

\frac{2 - 3}{3x - 2c} = \frac{7}{2c}

\frac{ - 1}{3x - 2c} = \frac{7}{2c}

Next, cross-multiply.

- 2c = 21x - 14c

12c = 21x

x = \frac{7}{4} c= 1 \frac{3}{4} c

The sides of a triangle are in the ratio 3 : 4 : 5. What is the length of each side if the perimeter of the triangle is 90 cm?
iogann1982 [59]
What we can do is set up an algebraic equation. 

our variable can me L for Length

3L+4L+5L=90

now all we have to do is solve

12L=90
----   ----
12      12

L=7.5

now multiple each number in the ratio by 7.5 to find out how long each side is

3 times 7.5 is 22.5
4 times 7.5 is 30
5 times 7.5 is 37.5

the side lengths are 22.5, 30, and 37.5
