 39 ) der r 2 effects 1) l affects output positively 2) land k are positively related so upward bias
37 ) problem of multicollinearity read more on it
33) uniform dist
p(z<0.5) = p(x<0.5,y<0.5) + p(x>0.5,y<0.5) + p (X<0.5,y.0.5) = o.5*0.5*3

as pdf = a+b/2 = 1+0 / 2 = 0.5

34) p(z<0.5/ x= 0.75) = p (x=0.75,y<0.5 ) = o.5
