Consider the following proability density function: f(x) = { kx. 0<= x< 2, k(4-x). 2<= x <=4, 0. otherwise. find the

Gnesinka [82]

The value of K for which f(x) is a valid probability density function is 1/4.

<h3>How to solve for the value of K</h3>

$\int\limits^4_0 {fx(x)} \, dx =1$

$\int\limits^2_0 {Kx} \, dx +\int\limits^4_2 {K(4-x)} \, dx =1$

$K[\frac{2^2}{2} -0]+[K[4(4-2)-(\frac{4^2}{2} -\frac{2^2}{2} )]=1$

open the equation

$K\frac{4}{2}+K[8 - (\frac{16}{2} -\frac{4}{2} )] = 1\\$

$2K+K[\frac{4}{2} ]=1$

2K + 2K = 1

4K = 1

divide through by 4

K = 1/4

Please help me do the equation and figure out the right solution. I am supposed to be correcting the one in the picture.

alexira [117]

Answer:

The correct answer is if you want no roots in the denominator, the correct answer is $\frac{2x}{y}$ * $\sqrt[3]{2y^{2} }$

Step-by-step explanation:

The mistake is that you can't take a cube root of a square at step 3 when $y^{2}$ is taken out.
