Answer:
In case of data set given with the question, the word that best describes the degree of overlap between the two data sets is low.
Step-by-step explanation:
Overlapping of two data sets means they contain common data or they have common elements in them.
In case of given data set, the elements are represented by 'x'.
If we compare both, the elements at line 30 and 35 overlap.
We conclude that out of 15 elements in each data set, only two of them overlaps. Hence the degree of overlap is low.

Julio did 6 divided by 2. which could've been fixed if he changed the division sign to multiplication and multiplied
