(a) Find the marginal probability density functions fX(x) and fY (y) of X and Y , respectively. (b) Are X and Y independent? (c) Find the conditional probability density functions fX|Y (x|y). For your limits (which you should not forget), give constant bounds on y, and then give the bounds on x as a function of y. (d) Find the conditional probability density functions fY |X(y|x). For your limits (which you should not forget), give constant bounds on x, and then give the bounds on y as a function of x.

answer: option a.

step-by-step explanation:

you know that the quadrilateral opqr ( a four sided figure) is inscribed in circle. this means that all its vertices are on the circle.

then, by definition, the opposite angles of the quadrilateral are supplementary, this means that the sum of their measures is 180 degrees.

you can observe in the figure that the angles ∠opq   and the angle ∠orq   are opposite, therefore:

then, can be used to d to calculate the measure of ∠opq

well kind of. you get friend requests. and you can accept them or not so yes.

step-by-step explanation:

the linear relationship that represents a variation in direct proportion is the linear function that varies according to the numbers of its domain, for example the cost of producing x number of items can be represented in direct proportion by f (x) = mx + b, where m is the constant of proportionality, x the number of articles produced and b the fixed cost
