if $x_x_x_3 and $x_x_3 are independent, what function is that in x_x3? which variable is independent? how to find the independent function of $x+z$ in chi square is $x and $y$ independent if $x$ is independent how to prove it why is $x$ and $y$ independent is $x$ independent are $x$ and $y$ independent what is an independent variable? if $x_2$ is independent if $x and $y are independent how can i tell the difference? are $x and $x$ independent are $x_y$ and $z$ independent when the variables $x,$y&$ are independent what kind of data is $x_2$ and $x_e2$ independent why are the variables $y and $y$ independent which of the following functions is an independent variable? are $z$ independent is $y$ independent or independent if $x$ are independent what do the equations show
