Answer: the answer is the 3rd bubble:)
Step-by-step explanation:
The chance that he will catch a grey squirrel is
82/147
but you are trying to figure out the chance of him NOT getting a grey squirrel so
147/147 - 82 /147 = 65/147
65/147 is your answer and you can not round that down anymore
Cos28=11/x
x=11/cos28
it will be c
Note that this just produces three parametric equations:



In the

plane, this is just he parametric equation for an ellipse (as a function of u). The z is simply a linear function.
The surface is then an ellipse extruded along the z-axis. We get a elliptic cylinder.
