The vega family has a 3-year cell phone contact. javier vega says that the family gets a total of 3x10 (4) (4 as an exponent) minutes of talk time to share during the 3 years. is javier correct or incorrect? explain.

What I think: Use this, please excuse my dear aunt Sally, e= exponent my=multiplication. 4 to the tenth power (10,000) times 3 is equal to 30,000 which means they all get 10,000 minutes (I Think)

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.

Could you make it more clear?
