Answer:

Step-by-step explanation:

According to this line of best fit, the likely test score of a student who does not study for the test is 38.

Not studying for a test is the same as doing 0 hours of homework (doing homework is considered studying).

A line of best fit is a straight line with half of the data, or points, on either side of it.

Let the universal set, s, have 66 elements. a and b are subsets of s. set a contains 19 elements and set b contains 34 elements.

Otrada [13]

The cardinality of the union between two sets is given by

$N(A\cup B) = N(A) + N(B) - N(A \cap B)$

In fact, if an element is in both A and B, it is counted in both N(A) and N(B), so we're counting it twice. By subtracting the cardinality of the interserction, we're taking back one of these "extra-counted" element, and the count is correct. In your case, the numbers are

$N(A \cup B) = 19+34-10 = 43$
