For which pair of integers are both points the same distance from 4 on the number line? a–1 and 10 b–2 and 8 c–3 and 9 d–2 and 10

The answer is D.  Look at a number line and start at -2 don't start counting until to move to get to 4, that would be 6 moves Then do it again this time start at 10 don't start counting until you move, that would be 6 moves as well.

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.
