The first step for each of these is adding or subtracting the coefficient to isolate your terms with variables. And then divide to isolate the variable itself.

. A construction company wants to submit a bid for remodeling a school. The research and planning needed to make the bid cost $4

Elenna [48]

Answer:

This project has a positive Expected Monetary Value, so it is expected to make money. This means that the company should be advised to make the bid.

Step-by-step explanation:

We have to find the expected monetary value of this project.

If it is positive, the company should make the bid. Otherwise, they should not make the bid.

There is a 20% probability of the bid being accepted. If the bid is accepted, the company would make $26,000 and lose $4,000. So the expected net earning is $26,000-$4,000 = $22,000.

There is an 80% probability of the bid being rejected. In this case, the company loses $4,000.

The Expected Monetary Value of the project is:

$EMV = 0.2(22,000) + 0.8(-4,000) = $1,200$ .

This project has a positive Expected Monetary Value, so it is expected to make money. This means that the company should be advised to make the bid.

Identify two additional values for x and y in a direct variation relationship where y =11 when x=18

Ann [662]

In a direct variation relationship the values must satisfy that y = kx. This si y is always a constant value (k) times x.

So, you can find multiple values that meet this:

y = kx => k = y / x = 11 / 18

=> y = (11/18)x

Now you can give any value to x and fint the value of x that satisfy the relationship:

x           y = (11/18)x

1           11/18

2           11/18 * 2 = 11/9

18          11/18 * 18 = 11

36           11/18 * 36 = 22

So, there you have several additional values for x and y in the same relationship that y = 11 and x = 18, and you can find many more using the same rule: y = (11/18)*x
