Let S = {Cyberdine, InGen, LexCorp, Omni, Tyrell, Umbrella, Weyland-Yutani}, A = {}. Then A' = { Cyberdine, InGen, LexCorp, Omni, Tyrell, Umbrella, Weyland-Yutani Enter the elements separated by commas. If the set is empty, enter "empty set". Explain it Practice Let S be the set of all integers and let N = {r ES | r < 0}. Then (mark all that are correct) A {pp is an a positive integer} N' = C {sS\s0} X E B {pp is an a negative integer} D {sS s>0} F None of the above
