Hello,
7) A∪C={1,2,3,4,5,7,9}
8) A∩B={2,4}
C'= complement of C ={2,4,6}
9) A∪B∩C'={1,2,3,4,6,8}∩{2,4,6}={2,4,6}
10) A∪(B∩C')={1,2,3,4}∩{2,4,6}={1,2,3,4,6}
Are you blind?
The
first choice gives you the same result. The factor of 5 can be removed to the outside of the summation symbol.
2.45cm=1 in
times both sides by 63
160.02cm=63 in
about 160cm
It’s not a function. the second option should be the right answer.
