A survey was taken of students in math classes to find out how many hours per day students spend
on social media. The survey results for the first., second-, and third-period classes are as follows:
First period: 2,4,3,1,0, 2, 1, 3, 1,4,9,2,4,3,0
Second period: 3,2,3,1,3, 4, 2, 4, 3, 1, 0, 2, 3, 1, 2
Third period: 4,5, 3, 4, 2, 3, 4, 1, 8, 2, 3, 1, 0, 2, 1,3
Which is the best measure of center for second period and why? (5 points)
1. Mean, because there are no outliers that affect the center
2. Median, because there is 1 outlier that affects the center
3. Interquartile range, because there is 1 outlier that affects the center
4. Standard deviation, because there are no outliers that affect the center

Mary beth used the mapping rule to find the coordinates of a point that had been rotated 90Β° counterclockwise around the origin. examine the steps to determine whether she made an error. m (3, β6) is rotated 90Β° counterclockwise. (x, y) β (βy, x) 1. switch the x- and y-coordinates: (6, β3) 2. multiply the new x-coordinate by β1: (6(β1), β3) 3. simplify: (β6, β3) .
