Answer :

Considering the given table and the periodicity concept, it is found that the data set is not periodic.

What is the period of a data-set?

The period of a function is given by the distance between it's repetitions.

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.
