B. 875 − g

Answer 25

i got it right :D

Answer 26

B is 875-g

Answer 27

lol thankfully I do know my graphs :P :)

Answer 28

the median does not change so this is tricky...

Answer 29

Im guessing that you add it

Answer 30

since fore example lets say we have 1,2,3,4,5
then 1+2+3+4+5=15/5=3
now lets say we add 2 to each value
3,4,5,6,7
3+4+5+6+7=25/5=5
so 5-2=2 which is the same increase as in the data
