false, because the complement of a set is the set of all elements that are not in the set.
True.
false
Yes. If all the question's parts are true, then the answer is true. If all the question's parts are false, then the answer is false. If one of the question's parts is false and the rest true, then the answer is false. Logically, this is illustrated below using: A = True, B = True, C = True, D = False, E = False, F = False A and B and C = True D and E and F = False A and B and D = False If you add NOT, it's a bit more complicated. A and NOT(D) = True and True = True NOT(D) and D = True and False = False NOT(A) and NOT(B) = False and False = False Using OR adds another layer of complexity. A OR NOT(E) = True OR True = True NOT(D) OR D = True OR False = False NOT(A) OR NOT(B) = False OR False = False Logic is easy once you understand the rules.
True. All squares are rectangles, but not all rectangles are squares.
Dictionary meaning's are all true they are not false.
true
It is true.
True
False. Not all living things on Earth are radioactive. Radioactivity is a natural process that can be found in some elements and materials, but it does not apply to all living organisms.
And is used in logical comparison in mathematics. true and true is true. true and false is false. false and true is false. false and false is false.
