Moment generating function and probability density function

Just need someone to explain to me step by step how this problem can be solved. My answer was wrong since I was not clear on how moment generating function was used in this area. My tutor in school was pretty vague on how to work this out as well. Respond to OTA: Basically the first equation is the joint pdf of a sample maxim ...continues

Greatest Common Factors

Find the GCF: (12,18), (16,20) (44,153) I tried to do on my own, I'm not sure if I understand what I am doing. If you can would it be possible to describe in details exactly what I should be doing. Thanks.

A certain engineering system can be represented by mass in a spring, as shown in Figure 1. If the mass is pulled downwards and then released, it oscillates on the spring. Using Newton¡¯s second law, a homogeneous second-order differential equation can be set up as below: If the mass m is 1kg and the spring¡¯s stiffness k is 100N/m, find an expression for the displacement x with respect to time t, when t=0, x(0)=0 and x`(0)=1 ...........Diagram .....
