The random variable X has the following probability density function: fX(x) = ( xe−x , if x > 0 0, otherwise. (a) Find the mo
ment generating function of X. (b) Using the moment generating function of X, find E[Xn] for all positive integers n. Your final answer should be an expression that depends only on n.
For this question, we can use formula - πr²(m/360). Here we are given m as 82 and r as 1.4cm. We can substitute values to get the area of the sector as approximately 1.4 cm²
