In practice, it is not often that you will need to work directly with the probability density function (pdf) of Gaussian variables. Nonetheless, we will make sure we know how to manipulate the (pdf) in the next two problems. If the pdf X is a Gaussian variable is fX(x)=n3/√2π exp(−n^2(x−2)^2 / 18), then what is the mean μ and variance σ2 of X?

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.

answer: yes i agree that you should not put it on/p>
