Let the difference between consecutive terms be D. If the middle term is 30, then the term before it is 30-D, and the term after it is 30+D. So the sum of these three terms would be (30-D) + 30 + (30+D) = 3*30.
Extending this sum to include all 11 terms centered around 30, we see that any addition of D is canceled by a balanced subtraction, leaving you with 11 copies of 30. So the value of the sum is 11*30 = 330.
1.rearrange your data from least to greatest:
<span>0,0,1,1,2,2,2,14 </span>
middle is 1 and 2 ... so median is 1+2/2= 1.5 and it is the median not the mean
2.I believe the only outlier is 50. Finding the mean would be 80.11.
<span>The answer would be D
</span>3.D. Mean always goes toward the skewness due to outliers.
<span>Median is minimally affected by outliers.
4.</span><span>We remove an outlier because we can simply assume that there was some type of extreme experimental error, or something went wrong. The mean shouldn't be effected that much, but the median will be greatly effected.</span>
Answer:
3b-2
Step-by-step explanation:
Answer:
C) -3m - 15
Step-by-step explanation:
Distribute -3 to all terms within the parenthesis:
-3(m + 5)
Multiply:
-3 * m = -3m
-3 * 5 = -15
-3m - 15 is your answer, or C)
