Math 101 Final Exam 1
Empty/Null Set - correct answer-NO Elements represented by ∅
roster form - correct answer-N
∈ - correct answer-element of
∉ - correct answer-is not an element of
set-builder notation - correct answer-A=(x|x∈ N and...)
A∩B (A Intersection B) - correct answer-What A & B have in common
(AUB)' (A union B) Complement - correct answer-U= What A & B both have
' (complement)= Whats not in either A or B
⊆ - correct answer-subset
⊄ - correct answer-Not a subset of
cardinal numbers - correct answer-represent by n
how many elements (numbers) are in A or B
Subsets - correct answer-2 to the power of cardinal number
Proper subsets - correct answer-1 less than subset
Round to the nearest tenth - correct answer-One decimal place. Example: 4.24 would be 4.2
Round to the nearest hundredth - correct answer-Two decimal places. Example: 10.527
would be 10.53.
Round to the nearest thousandth - correct answer-Three decimal places. Example: 15.1935
