o a quantitative values only and not qualitative things.
o b fact and not opinion.

question 8 (1 point)
what is meant by the complement of a set a?
o a all of the elements in set a.
o b all of the elements that are not in set a, but are in the universal set.
o c the antonyms of set a elements.

Explanation:

Question 7: A well - defined set has a clear rule for membership. Facts provide an objective basis (e.g., "all prime numbers less than 10"), while opinions (e.g., "all beautiful paintings") are subjective.
Question 8: By definition, the complement of set \(A\), denoted \(A'\) or \(\overline{A}\), is \(A'=\{x|x\in U,x
otin A\}\) where \(U\) is the universal set. Option A is just the set \(A\) itself, and option C has no relation to set - complement concepts.

Answer:

Question 7: B. fact and not opinion.
Question 8: B. All of the elements that are not in Set A, but are in the universal set.
