Joe has been given a treasure map on which he must plot three points. there is a portion of the treasure at each point. point a is at (-4,0), point b is at (-4,5), and point c is at (4,2). if joe has already found his at point a, how far must he walk to get to point b? i think it has something to do with a coordinate plane, i'm not sure.

Abby is collecting rainfall data. she finds that one value of the data set is a high-value outlier. which statement must be true? abby will use a different formula for calculating the standard deviation. the outlier will increase the standard deviation of the data set. the spread of the graph of the data will not change. abby will not use the mean when calculating the standard deviation.
