I would need help with problem #22, please? 22. The figure shows the torus obtained by rotating about thez-axis the circle in the xz-plane with center (b, 0, 0) andradius a < b. Parametric equations for the torus arex = b cos 0 + a cos a cos 0y = b sin + a cos a sinz = a sin awhere and a are the angles shown in the figure. Find thesurface area of the torus.Z(x, y, z)X*(b, 0, 0)αy

I am a brazen lion, a fountain; my spouts are my two eyes, my mouth, and the flat of my right foot. My right eye fills a jar in two days [1 day = 12 hours], my left eye in three, and my foot in four; my mouth is capable of filling it in six hours.

For the remainder of this question, we will consider one of the world's most popular video games, Minecraft (adapted from Mills & Mills, 2016). In this game, the character (you) can attempt to tame a wolf with a bone. Assume that you get 9 tries to tame the wolf, i.e. there are 9 bones. Each time you tame the wolf, the wolf becomes a dog and a new wolf appears which you can then attempt to also tame. This continues until you have used up all 9 bones, and the goal is to end up with as many dogs as possible at the end of the game. The probability of taming the wolf with each attempt is fixed at 0.54. Let X denote the number of dogs at the end of the game so that X BIN (9,0.54). Assume you are about to play the game. 12. What is the probability you will tame less than 4 dogs?
