Answer 10

okay let me rewrite that 17+19=? divide that answer by 2

Answer 11

ok and it = 18

Answer 12

okay without the 1000 the median is 17...so he median increased by one

Answer 13

which means we can eliminate C

and we know the mean will not stay the same because we are adding another huge number

Answer 15

ok

Answer 16

Which leaves us with A and D
