Answer:
a) 0.96
b) 0.016
c) 0.018
d) 0.982
e) x = 2
Step-by-step explanation:
We are given with the Probability density function f(x)= 2/x^3 where x > 1.
<em>Firstly we will calculate the general probability that of P(a < X < b) </em>
P(a < X < b) = =
= { Because }
= =
= =
a) Now P(X < 5) = P(1 < X < 5) {because x > 1 }
Comparing with general probability we get,
P(1 < X < 5) = = = 0.96 .
b) P(X > 8) = P(8 < X < ∞) = 1/ - 1/∞ = 1/64 - 0 = 0.016
c) P(6 < X < 10) = = = 0.018 .
d) P(x < 6 or X > 10) = P(1 < X < 6) + P(10 < X < ∞)
= + (1/ - 1/∞) = 1 - 1/36 + 1/100 + 0 = 0.982
e) We have to find x such that P(X < x) = 0.75 ;
⇒ P(1 < X < x) = 0.75
⇒ = 0.75
⇒ = 1 - 0.75 = 0.25
⇒ = ⇒ = 4 ⇒ x =
Therefore, value of x such that P(X < x) = 0.75 is 2.
The distance between two points:
(x₁,y₁), (x₂,y₂) - the coordinates of the points
The answer is A.
Answer:
Step-by-step explanation:
From our knowledge of derivatives we use the product rule approach, the product rule is stated below
For f(x)=u(x)v(x) the derivative is express as
hence from the question f(x)=2xlnx,
we can assign u(x)=2x and v(x)=lnx
also the derivative of u(x)=2x is simply
and the derivative of v(x)=lnx can be express using the general log derivative i.e
hence we have
if we substitute value into the general product expression stated earlier we arrive at
