The discrete uniform distribution is on the interval 8 ≤ x ≤ 10.
Therefore the probability density function (shown in the figure) is
P(x) = 1/3 = 1/3 for x = 8, 9, 10
= 0 otherwse
The mean is μ = 1/3.
The variance is
σ² = Σp(x) (x- μ)²
Because x - μ = 0 for x = 8,9,10, therefore
σ² = 0
Answer:
μ = 1/3
σ² = 0

Answer:
First of all, find x from the Pythagorean theorem , which c is the hypotenuse.
c=25 or x=25
Next, we have to figure out the value of y and z. So, you need to use inverse trigonometric functions.
arctan degrees. arctan
degrees.
All in all, the values are
x=25
y=16.3
z=73.7
Hope this helps and have a nice day!
