What is the value of x in the equation? 5 1/6 x + 2 1/4 = 10

5 1/6 = 31/6
2 1/4 = 9/4

31/6 x + 9/4 = 10
31/6x = 10 - 9/4
31/6 x = 40/4 - 9/4
31/6 x = 31/4

Multiply 6 in both sides and divide 31 on both sides:

1/6x = 1/4
x = 6/4 = 3/2

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.
