No, because if you add 184 and 145 you get 329. then you would take 329 and divide it by 60 because that’s how much each mold holds. that comes out to be 5.48 (rounded). you would be able to fill 5 molds, but not enough batter for 6
Answer:
-24x + 18y
Step-by-step explanation:
6 x -4x = -24x
6 x 3y = 18y
You can see the answer from the picture

(1) Looks like the joint density is

In order for this to be a proper density function, integrating it over its support should evaluate to 1. The support is a triangle with vertices at (0, 0), (4, 0), and (4, 4) (see attached shaded region), so the integral is


(2) The region in which <em>X</em> > 2 and <em>Y</em> < 1 corresponds to a 2x1 rectangle (see second attached shaded region), so the desired probability is

(3) Are you supposed to find the marginal density of <em>X</em>, or the conditional density of <em>X</em> given <em>Y</em>?
In the first case, you simply integrate the joint density with respect to <em>y</em>:

In the second case, we instead first find the marginal density of <em>Y</em>:

Then use the marginal density to compute the conditional density of <em>X</em> given <em>Y</em>:
