what is the generalization of the x value if $x is fixed when does the ___ represent the variance of the product of two independent random vectors? how to generalize variance what is generalized value of v_x can you find the b value in an equation of the same random vector what is the value of covar x i which of the following is a generalized variable of an independent random vector? how to generalize the formula for the random vector times random matrix x i linear distribution if value is fixed what is covar? what is the generalized variance of a random vector based on what is the value of variance of the random vector times the random matrix if x_i is fixed, which variable in the physicist should be generalized? how to generalize random vector times variable how to get x in a random vector matrix how to generalize random vector times random matrix if y_i is fixed, what is $$ covar(x_i, x_j) equal how to generalize the random vectors how to generalize the equation for random vector of independent random vector how to generalize value of $b$
