The joint probability density function of x and y is given by f(x, y) = c(y 2 − x 2 )e −y , −y ≤ x ≤ y, 0 < y < [infinity] (a) find c. (b) find the marginal densities of x and y . (c) find e[x].
that is the sum of the interior angles of a triangle,or the 3 sided polygons
it's rational, it doesn't go on and on or has long repeating patterns.
hi my dear friend,
a bisector is a line that intersects two or more lines in different points.
