9. Mr. Schwartz gives his class a challenge problem. Five students take 2. 12, 10, 11, and 15 minutes to solve it. How does the outlier affect the mean
of the data? *
It makes the mean less than it would be otherwise
It makes the mean greater than it would be otherwise
It makes the mean equal to the median
It has no effect on the mean

180°

step-by-step explanation:

sum of equilateral triangle=180°

< n=60°

< m=120°°[angle supplementary of equilateral angle]

< m+< r+< x=360°(sum of exterior angle of triangle)

answer:

the answer is b) divide by -4 on each side and flip the sign.

step-by-step explanation:

we first need to start by dividing. this is because it is a multiplication problem to start.

we also need to make sure we flip the sign because any time you multiply or divide by negative numbers, the sign must be flipped.
