Answer:
multiply by 25 also.
Step-by-step explanation:
If the scores are multiplied by 25, that means that the mean will also multiply by 25. Since the mean and the scores all increased by 25 times, the standard deviation will increase by 25 times.
If instead, you added 25 (or any other number) to each score, then the standard deviation would not change. The mean and each score will increase by 25, bu the difference between them will not change.
Answer: y=-2x-9
Step-by-step explanation:
Add 4x to both sides because the slope (-2x) needs to be on the same side as the y-intercept (-9). Then divide everything by 2 to get your answer because you want to get y by itself, since there is two of them. 2y-4x=-18 becomes y=-2x-9.

Answer:
A=32 m^2.
Step-by-step explanation:
The formula for the area of a rhombus is A=pq/2.
The p is the vertical part of the rhombus and the q is the horizontal part of the rhombus.
<em>A=(8)(8)/2.</em>
<em>A=64/2.</em>
<em>A=32 m^2</em>
