On a string instrument, the length of a string (1 cm) and
the frequency of its vibrations
(v Hz) are modelled by the
1000
equation v =
a. Sketch the function for
b. Find the frequency of vibration if the length of the
string is 10 cm long.

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.

Graph a should be your answer
