Answer:
C
Step-by-step explanation:
Parallel line slopes are always the same.
6
2+x=8
Subtract 2 on both sides
x=6
This is not possible. Why not? Because the smallest the variance can get is 0.
Recall that 's' represents the standard deviation, so s^2 is the variance. It basically measures how spread out the values are. The higher the variance, the more spread out the data. You can think of it as "average distance from the mean". If the variance is 0, then all of the values are at the same point. So you could have a list like {2,2,2,2,2} which has variance 0. We cannot get any smaller variance than that. If your teacher insists all the values in the list are different, then the variance will be greater than 0.
Step-by-step explanation:
No because they 90 to 200 is 110 but 200 to 325 is 125
110 obviously does not equal 125
