Thee correlation factor formula for two variables is
(r) =[ nΣxy – (Σx)(Σy) / Sqrt([nΣx^2 – (Σx)^2][nΣy^2 – (Σy)^2])].
A). as per the formula the correlation factor for the given data is 0.94.
B). the month of September has the highest correlation as 0.94 is much closer to 1 than 0.89.( note: 1 denotes the perfect correlation and 0 denotes no correlation at all)

A y=3x because 3*1 is 3 and 3*2 is 6 and so on
34 is larger than 3, so 34.653
D
is the answer because 6 is lonely but on new equation 13 and 6 disspapeared so the added answer is 19 which is letter D.
