A bag contains green marbles and blue marbles, 55 in total. The number of green marbles is 7 more than 5 times the number of blu
MrRissso [65]

Answer:

Step-by-step explanation:

Total marbles in bag= 55

Given that

The number of green marbles is 7 more than 5 times the number of blue marbles.

Let green marble be x

And blue marble be y

Therefore,

Green=seven more than 5 times blue

Green=7+5timesblue

x=7+5y. Equation 1

Also the sum of the marbles is 55

x+y=55. Equation 2

Substitute equation 1 into 2

7+5y+y=55

7+6y=55

6y=55-7

6y=48

y=48/6

y=8

From equation 2

x+y=55

Then, x=55-y

x=55-8

x=47

Then, green marbles is 47.

Also, Blue marbles is 8

You are evaluating the risks associated with a construction project. Through careful analysis you have developed a list of the f
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
