Show work below.

find the vertices,foci and asymptotes of the hyperbola and
sketch its graph y^2/25-x^2/9=1
show all work and step

1. Find P{X = x} for x = 0, 1, 2, 3, 4, 5 for a Bin(5, 3/7)
random variable.
2. Find the first and third quartiles as well as the median for
a Beta(3, 3) random variables.
3. Find P{X ≤ x} for x = 0, 1, 2, 3 for a χ 2 2 random
variable.
4. Simulate 80 Pois(5) random variable. Find the mean and
variance of these simulated values.

a. Find (d) (e)
b. Find (3a) (7c)
c. Find Pe --> d
d. Find Pc --> a +2b
ex. C = |x|(xy/xy) C = xy/|x|
ex. P x --> y = Cux = C(xy/x) (1/|x|) (x) =( xy/yy)(y)
