Answer:
it is 1/2 of 1
Step-by-step explanation:
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 answer is D, y - 4 = -2(x - 1).
Point Slope Form: y - y₁ = m(x - x₁)
Info Given:
Coordinates - (1,4)
Slope: -2
(1,4)
x₁ y₁
Plug slope and point into formula: y - 4 = -2(x -1)
If the entire class lasts 7/8 of an hour, then it lasts 52.5 minutes as:
60/8 * 7 = 52.5mins or 52min 30secs
a) Then warm up and cool down lasts 3/10 of the class so this is:
52.5/10 * 3 = 15.75mins or 15min 45secs
b) Instruction is 1/5 of the class so 4/5 is not spent on instruction so:
52.5 / 5 * 4 = 42mins
