Consider three independent random variables X, W1, and W2. Construct two new random variables Y1 and Y2 from simple algebraic combinations of X, W1, and W2 such that Y1 and Y2 are not independent, but are conditionally independent given X.

the answer is 15% decrease

answer:   b

step-by-step explanation:

x2 = 16

x can not be a negative number because 16 is positive

the only answer would be positive 8  

answer: on graphs, the open and closed circles, or vertical asymptotes drawn as dashed lines us identify discontinuities.

as before, graphs and tables allow us to estimate at best.

when working with formulas, getting zero in the denominator indicates a point of discontinuity.

when working with piecewise-defined functions, check for discontinuities at the transition points where one piece ends and the next begins.
