3points lie on an xy plane, with each point representing where a particular person lives. amy lives at point (2,3); brian lives at point (0,7); and claire lives at point (-2,3). they all wish to meet up with each other for lunch, but at a location that is equidistant from each of their respective houses. at what point do they meet?

The equidistant point for all three, will be the "centroid" of their triangular locations
thus 

Ifound this on google “a skewed (non-symmetric) distribution is a distribution in which there is no such mirror-imaging. a "skewed right" distribution is one in which the tail is on the right side. a "skewed left" distribution is one in which the tail is on the left side. the above histogram is for a distribution that is skewed right.” i hope this you for what your looking for
