Let x have pmf p(x = k) = cpk k fork = 1, 2, . . where p is a parameter with 0 < p < 1 and c is a normalizing constant. we have c = −1/ log(1 − p), as seen from the taylor series − log(1 − p) = p + p2/2 + p3/3 + this distribution is called the logarithmic distribution (because of the log in the above taylor series), and has often been used in ecology.
(a) show that the pmf is a valid pmf.
(b) find the mean and variance of x.

The image of abc is a'b'c. what transformations would result in this image? abc is reflected over the line x = 1, then is rotated -90° around the origin. abc is reflected over the line y = x - 1, then t: (x, y) → (x - 1, y - 1). abc is rotated 90° around the origin, then is reflected over the y-axis. abc is rotated -90° around the origin, then is reflected over the line y = -1.
