X/w=y/5
wy=5x
wy/5=x
w/5=x/y
it should be a
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
Answer: The length is 14cm
Step-by-step explanation:
52=2(2x-2)
26=2x-2
28=2x
x=28/2=14
