Answer:

2x square -25x + 7

Step-by-step explanation:

a square - (b+c)

(3x-4)square - {(x+7)+(x square+2)}

3x square-2.3x.4+4 square - (x+7+x square+2)

3x square - 24x + 16 -x - 7 - x square - 2

3x square - x square -24x - x + 16-7-2

2x square-25x+7

or,

x(2x - 25)+7

Assume there is probability of 0.36 that a U.S. soldier who served in the last decade has served in Iraq. If a soldier served in
taurus [48]

Answer:

0.440559

Step-by-step explanation:

To find the probability of having a soldier from Iraq that had lung problems, we multiply the 2 probabilities, so 0.36*0.14 = 0.0504

The probability of a soldier serving not in Iraq and having lung problems is 0.64 (serving in Iraq is 0.36, so not serving in Iraq is 1 - 0.36 = 0.64) times 0.1 = 0.064.

If we sum up these two probabilities, we have the probability of a soldier having lung problems (0.0504+0.064 = 0.1144).

Now, to know the probability of a soldier with a lung problem having served on Iraq, we divide the probability of serving in Iraq and having lung problems (0.0504) by the probability of having lung problem (0.1144):

0.0504/0.1144 = 0.440559

Please help me... the perimeter of square WXYZ is 20 units. The coordinates of three of the vertices are W(3,2), X(3,7), and Y(8
Blababa [14]
Okay, so we know that the perimeter of the square is 20. Since a square has 4 equal sides to find the length of one side, 20/4. Each side is equal to five. Look at each of the coordinates and put them respectively into a graph in your mind. w(3,2) (bottom left) x(3,7) (top left) Y(8,7) (top right). Now we know we need to find the bottom right coordinate. Being that both of the coordinates on the left have the same x value we can justify that the coordinates on the right have the same X value also. we can say this same thing for the y coordinate. Since both coordinates on the top of the square have the same Y value, we can justify that the coordinates on the bottom have the same Y value. So taking the coordinates we now are the same, the answer is Z(8,2). We can check his by seeing if the distance if five from each of the adjacent coordinates. If you have any questions comment below.

Joe went to the hobby shop and bought 2 model sports cars at $8.95 each and some paints. If he spent a total of $23.65, what was
Nostrana [21]
We have 2 cars at $8.85 each. So we have 8.85 * 2 = $17.70

If we know he spent 23.65, we can do 23.65 - 17.70 = 5.95

So the paint must have cost $5.95.

What is the slope intercept form of 3x-2y=-16 with steps. Please explain.
8_murik_8 [283]
3x - 2y = -16

Slope intercept form is y = mx + b, so solve it for 'y'

First subtract 3x to both sides:

-2y = -3x - 16

Now divide -2 to both sides:

y = 3/2x + 8
