If 9 points X1, X2, ..., X9 are chosen on a straight line in that order (but not necessarily evenly spaced), and Y is an arbitrary point on the line and S is the sum of the distances YX1, YX2, ..., YX9, then S is minimized when the point Y is
Read Solution (Total 1)
-
- for s to be minm,sum of the distances YX1, YX2, ..., YX9 should be minm
its possible when y lies midway of9 points X1, X2, ..., X9
i.e at x5
hence S is minimized when the point Y is x5
