There are over 2700 species of snakes in the world. over 600 species are venomous. write the fraction of species that are not venomous as a decimal.

The answer is 0.7777... (0.7 repeating).

Explanation:
Since there are 600 species that are venomous, there are 2700-600=2100 that are not venomous.

This is out of 2700 species; 2100/2700 = 7/9. Dividing 7 by 9, we get the decimal 0.7 repeating.

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.
