Which word best describes the degree of overlap between the two data sets? low, high, none, moderate

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.

the answer is b.

step-by-step explanation:

by the trigonometric ratio tangent, tangent equals opposite divided by adjacent.

therefore, tan(50) equals ac/3

multiply each side by 3 to get: ac=3tan(50)

the answer is b.
