If you are reflecting across the x axis then the x coordinate will stay the same and the y coordinate will be negative. Draw a picture to help you see this.
That puts P prime in quadrant IV.
Answer:
(a) $2000
(b) $94.9
Step-by-step explanation:
The expected $ value of signing 100 deals with probability of 0.1 each is
E(X) = 100*0.1 + 100*0.1 + 100*0.1 + ... + 100*0.1 = 100(100*0.1) = $1000
Along with the fixed amount of $1000, the total next month salary is $2000
As for the standard deviation we can apply the following formula
![\sigma = E(X^2) - E(X)^2](https://tex.z-dn.net/?f=%5Csigma%20%3D%20E%28X%5E2%29%20-%20E%28X%29%5E2)
![\sigma = \sqrt{0.1*(100 - \mu)^2 + 0.1*(100 - \mu)^2 + ... + 0.1*(100 -\mu)^2}](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%5Csqrt%7B0.1%2A%28100%20-%20%5Cmu%29%5E2%20%2B%200.1%2A%28100%20-%20%5Cmu%29%5E2%20%2B%20...%20%2B%200.1%2A%28100%20-%5Cmu%29%5E2%7D)
![\sigma = \sqrt{0.1*100*(100 - 1000)^2}](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%5Csqrt%7B0.1%2A100%2A%28100%20-%201000%29%5E2%7D)
![\sigma = \sqrt{10*900^2} = \sqrt{9000} = 94.9](https://tex.z-dn.net/?f=%5Csigma%20%3D%20%5Csqrt%7B10%2A900%5E2%7D%20%3D%20%5Csqrt%7B9000%7D%20%3D%2094.9)

Distance between the 2 birds is 2.5 - (-2.5), or 5.0 (units).
