The annual maximum rainstorm produces rainfall depths (R) in inches at a site of interest that follow a lognormal distribution with a mean of 4.2 in. and a standard deviation of 1.1 in. (a) Compute the parameters of the lognormal distribution.
(b) Compute the magnitude of the 20-year storm (ie. the 95th percentile).
(c) The drainage system at the site can handle 6 in. of rainfall. Anything beyond that will result in flooding.
Determine the probability that the drainage system will not meet demand for such events.

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

range is infinite on both x and y axis positive and negative

step-by-step explanation:

in the math equation 8 x 7 = 56, the 8 and the 7 are both factors of 56, since in this lesson we will use square tiles to figure out the factors of a whole find as many different arrays as you can, but follow one important rule: all the rows must have the i can make two rows of nine, so 2 and 9 are both factors of 18.
