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

Give the domain and range of the relation. y=(x+4)^2-4

Westkost [7]

Answer:

The domain is the interval (-∞,∞)

The range is the interval [-4,∞)

Step-by-step explanation:

we have

$y=(x+4)^2-4$

This is the equation of a vertical parabola in vertex form

The vertex is the point (-4,-4)

The parabola open upward (because the leading coefficient is positive)

The vertex represent a minimum

The domain is the interval (-∞,∞)

so

The domain is all real numbers

The range is the interval [-4,∞)

$y\geq -4$

so

The range is all real numbers greater than or equal to -4

The strategy

Model the situation as a right triangle.

Determine the appropriate trigonometric ratio in order to find the missing angle.

Form an equation and solve for the missing angle.

Calculate the final result and round.

Modeling as a right triangle

This situation can be modeled by the following right triangle. The hypotenuse is 100 meters and the height is 42 meters. We are asked to find the angle of elevation, which is the angle on the left.

Determining the appropriate trigonometric ratio
We are given the side opposite to the missing angle and the hypotenuse The appropriate trigonometric ratio is therefore the SINE.

Forming an equation and solving

Denoting the missing angle by θ, we obtain the equation $sin(0)= 42/100$ 

Solving the equation, we get $0=sin^-^1 (42/100)$

Evaluating this result in the calculator and rounding to the nearest tenth, we get θ = $24.8^0$ degrees.
