You’re working with two random variables x and y , which may be dependent and for which v (x) = v (y ). show that the random variables w = (x+y ) and z = (x−y ) are uncorrelated. hint: nothing fancy — just simplify the covariance of w and z, using properties of covariance.

answer: 33 ( approx)

step-by-step explanation:

since, in the linear regression formula, the slope is the a in the equation y = b + ax ( by comparing it with the general equation of line y = mx + c )

where,

here given table is,

price ($), x   :           18         23       25       29       30       33

pairs sold, y :         16         13         10       8         6       2

so, ,   ,   ,

and   ,

thus, slop of the given line is,

⇒  

⇒   ≈ 33
