4 multiplied by the sum of y and 7 is equal to 16

4(y+7) = 16
Make sure the makes sense so 4 is going to be first because it’s 4 outside of (y+7) so once you do y+7 you multiply by 4 then that should equal 16

Ifound this on google “a skewed (non-symmetric) distribution is a distribution in which there is no such mirror-imaging. a "skewed right" distribution is one in which the tail is on the right side. a "skewed left" distribution is one in which the tail is on the left side. the above histogram is for a distribution that is skewed right.” i hope this you for what your looking for
