I post the questions few times but all times tutors gave the wrong solution, i give them 1 downvote. Don't answer my questions again who already gave me the answer.now i will give them multiple down votes. I also give you the multiple times down votes who will give me the wrong answer for my Statistics questions. Don't reject my question, if you don't know the answer, leave it for other tutors.

if 2 2 = ax + by and r is the correlation cofficient between the two
that is x and y. You have to show that 82 =
a²0x² +6²³y² +2ablx@y
You also have to show that the correlation coefficient to between two handom
Vapiables X and Y and is given by
r^² (0x² + y² - 0x²³x- y²) 28 x0y¹`
from the above data Ox, AY and Ox sure the Standard devations of
X₁, and X-Y nespectively.
please use the formalia (STND).
