You've got a formula. If the two endpoints are $A(x_A,y_A)$ and $A(x_B,y_B)$ , then the length is $\sqrt{(x_B-x_A)^2+(y_B-y_A)^2}$ . The result is $\sqrt{16+25}=\sqrt{41}$ .

. 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.

What equation is graphed in this equation?

jenyasd209 [6]

Y-2=-3/2(x-2)
first of all, the slope of the line is -3/2, and there's only one equation that has that as a choice for the slope. Then you can take the x and y coordinates given in that equation you want to check and see if the line goes through that point. from the equation, (point-slope form y-y=m(x-x)) I know that the line should pass through point (2, -2), and looking at the graph, that is correct.

C. The quotient of 3 and a number x.

Yakvenalex [24]

The answer you are looking for is 3÷x. Well, the better way to write this would be 3 over x, or 3/x, which is the fractional form. Since "quotient" modifies division, you would divide 3 by x.

So, therefore, the best final answer to this problem is 3/x.

Hope this helped answer your question for you. Good day to you.
