Ihave 132 red and blue marbles in a bag. the ratio to blue to red marbles is 8: 3. how many blue marbles are there?

The answer to your questions is that there is 132 and the ratio is 8:3. so you divide 132 by 11 and get 12 you then multiply 8 by 12 which gives you 96 blue marbles.

divide 132 by 11 by 8 by 12 the answer is 96

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.
