Pacman consists of the space above the region pictured, and below the upper hemisphere center (0 , 0 , 0) and radius 1, together with the corre- sponding space below the xy -plane and above the lower hemisphere. Find the volume of Pacman. (4 points) 2. Set up integrals of a general function f ( x, y ) over the regions pictured. Use whichever of Cartesian and polar coordinates gives a simpler integral. (3 points) 3. The floor of a box, modeled by [0 , 2] × [ - 1 , 1] is heated, with the heat coming in at the left hand edge. The position of a mouse is governed by the probability density function m ( x, y ) = (2 - x ) / 4 if 0 x 2 and - 1 y 1 0 otherwise . Find the probability the mouse is in the left-hand (warmer) half of the box. (3 points) 1

What students are saying

• As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

• I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

• The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
