Answer:
See below.
Step-by-step explanation:
An outlier can affect the mean by a lot. For example, if my neighbor moves out and Bill Gates moves in (he would be a <u>super</u> outlier!), the mean annual income would increase enormously.
The median, on the other hand, would not change at all. The income in the middle is still the income in the middle; Gates' income would not budge the median.
Answer:
The second one
Step-by-step explanation:
Additive identity is adding 0 to a number
The fraction with the smaller denominator is the greater number.
9n + 4n^2 because you combine like terms. combine the two n's that are not squared then add the two n^2 together to get 9n+4n^2
