I think its D <em>(or #4 - He Should use the mean because there are no outliers that affect the mean)</em> because the Median would be $175,000 but the Mean would be $638,400. It's honestly almost up to you.
Answer:
make the y int -4 because it passes through (0,-4). to make perpendicular, apply same slope to new equation but change sign
equation:
3x -4
The correct answer should be D
Answer:
C
Step-by-step explanation:
The right triangle on the right side of the figure has a height of 6 (two same sides lengths) and a base of 3.
x is the hypotenuse (side opposite of 90 degree angle).
We can use the pythagorean theorem to find x. The pythagorean theorem tells us to square each leg (height and base) of the triangle and add it. It should be equal to the hypotenuse square.
For this triangle it means, we square 6 and 3 and add it. It should be equal to x squared. Then we can solve. Shown below:

<em>Now we can use property of radical
to simplify:</em>

Correct answer is C
