Danielle knows that a dollar bill is half a foot long. how could she use the dollar to measure a mat for her desk that should be 1 2/3 ft. by 5/4 ft? (btw i'm in middle school not highschool)

For a lenght of a desk which needs to be 1 2/3ft long, Danielle can use 1 hole dollar bill and she will need 2/3ft more.  1/2ft*x=2/3ft, x=4/3.
So for lenght she will need 1 hole dollar bill and 4/3 of a dollar bill more.
For width of table she need 5/4ft. 1/2ft*x=5/4ft, x=5/2.
So for width of table she will use 5/2 of a dollar bill.

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.
