Considering the given table and the periodicity concept, it is found that the data set is not periodic.
<h3>What is the period of a data-set?</h3>
The period of a function is given by the <u>distance between it's repetitions</u>.
An example of a periodic data-set with a period of 3 would be 1,2,3,1,2,3,1,2,3,...
In this problem, looking at the table, it is found that there are no patterns of repetitions, that is, the number of cars washed do not follow a repeated pattern, hence the data set is not periodic.
