what is the trigonometric ratio for cosn ?

enter your answer, as a simplified fraction, in the boxes.

Cos n=A/H=36/39
=12/13

THERFORE, COS N=12/13

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.
