Answer:
attached below
Step-by-step explanation:
Assuming that Y1 and Y2 are independent exponential random variable with mean 3
where : U = Y1 + Y2 applying the property of exponential distribution sum of exponentials will follow a gamma distribution
i.e. ∝ = 2 , and β = 1
note : U = 2X
Hence probability distribution function X =
Fx (x) = p( X ≤ x )
= p( U ≤ 2x )
= Fu (2x)
probability density function X
f (x) = = 2 Fu (2x)
attached below is the remaining part of the solution
The volume of a cone is one third of the volume of a cylinder that has the same base and height.
The answer is 36/3=12pi in^3.
Answer:
Step-by-step explanation:
<u><em>The question is</em></u>
Find the value of XY
see the attached figure to better understand the problem
we know that
-----> by segment addition postulate
If X is the midpoint WY
then
substitute in the formula above
substitute the given values and solve for XY
Subtract 6 both sides
Divide by 2 both sides
Rewrite
120/300 is equal to 40/100 or 40 percent.
Answer:
14 cm.
Step-by-step explanation:
The formula for the perimeter of a rectangle is P = 2l + 2w, where P is the perimeter, l is the length, and w is the width.
In this case, the width is 4 cm and the length is 3 cm.
P = 2(3) + 2(4)
P = 6 + 8
P = 14
So, the perimeter of the rectangle is 14 centimeters.
