Determine whether the vectors u and v are parallel, orthogonal, or neither.

u = < 9, 3> , v = < 36, 12>

Well I dont remember the math part of this but I believe that they are Parallel because of the fact that they all can go into 3

The major difference is that a histogram is only used to plot the frequency of score occurrences in a continuous data set that has been divided into classes, called bins.  bar charts, on the other hand, can be used for a great deal of other types ofvariables  including  ordinal  andnominal  data sets.
