What value corresponds to the 60th percentile in the following data set?

{12, 28, 35, 42, 47, 49, 50}
1) 47
2) 49
3) 28
4) 42

60th percentile is the 60/100 x (7 + 1)th number = 5th number

60th percentile is 47.

Skew lines(segments) are lines(segments) in 3 dimensions that do not intersect the given segment and are not parallel to it.  ae, bf, eg, and fh are your skew segments.  i hope that : )
