[tex]\sum_{i=1}^{n} (y_i\theta)=n\theta[/tex]
where theta is a fixed constant and [itex]y_i[/itex] is a discrete random variable. does anyone know how to rewrite in close form?? also, everytime i use latex it starts a new line. how can i fix this so i can type directly with my sentances? thanks

Instead of using "tex" use "itex".

Or are you using the notation "..." to mean "expected value" instead of "absolute value"?
