यह दिया गया है कि `barX=10, barY=90, sigma_(x)=3, sigma_(y)=12` और `r _(xy) =0.8` है । X पर Y कस समांसरयण समीकरण क्या होगा ?

If r = 0.5, sigma_x =3, sigma_y^2=16 then b_(yx) =…

If r=0.5,sigma_x=3 ,sigma_y^2 =16 then b_(xy) = .....

It is given that barX=10, barY=90, sigma_(X)=3, sigma_(Y)=12 and r_(XY)=0.8. The regression equation of X on Y is

If sigma_(x) = 3, sigma_(y) = 4 , and b_(xy) = (1)/(3) , then the value of r is

If barx=18,bary=100, sigma_(x)=14,sigma_(y)=20 and correlation r_(xy)=0.8 , find the regression equation of y on x.

Find r(x,y) if cov (x,y) =-16.5, var(x)=2.25 and sigma_(y)=12

For alpha and beta both being acute angles, it is given that sin (alpha+beta)=1, cos (alpha-beta)=1/2 . The value of alpha and beta are: alpha और beta दोनों न्यून कोण है, और यह दिया गया है कि sin (alpha+beta)=1, cos (alpha-beta)=1/2 है। तो alpha और beta का मान क्या होगा?
