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.
2 barrettes that measure 1/4-inch each. So we need to add them together
1/4+1/4=2/4-inch
this can be simplified to 1/2-inch
Answer=1/2-inch
Since it's not a domain restricted function anywhere, the domain of this function is (-∞, ∞). Because the x is squared, you will <em>never </em>get a negative answer, and therefore, the range is either (0, ∞) or {x: x > 0}. Hope this helps you out!
The correct answer is B 26!/21! turned this in already and gotten a 100. Hoped this helped ya.
