A plane is heading due south with an airspeed of 211 mph. A wind from a direction of 53 degrees is blowing at 17 mph. What is the bearing of the plane?
Two line segments, each of length two units, are placed along the x-axis. The midpoint of the first is between x=0 and x=14 and that of the second is between x=6 and x=20. Assuming independence and uniform distribution for these midpoints, find the probability that the line segments overlap. Show...
Suppose X and Y are random variables of the discrete type which have the joint pmf p(x,y) = (x+2y)/18, (x,y)= (1,1), (1,2), (2,1), (2,2), aero elsewhere. Determine: (Show work in all parts) a) The conditional mean and variance of Y given X=x, for x=1,2. b) The variance of the conditional mean...

Tips for asking Questions
- Provide any and all relevant background materials. Attach files if necessary to ensure your tutor has all necessary information to answer your question as completely as possible
- Set a compelling price: While our Tutors are eager to answer your questions, giving them a compelling price incentive speeds up the process by avoiding any unnecessary price negotiations
1. I’m having problems with my math. Can you help me? All I need is an example just to make sure I'm on track.
- Solve the following
- a) 3/(n+1)-1/(n+1)=14/(n^2-1)
- b) 1/(y-1 )+y/(1-y)
- d) (x-2)/(8x-24)*(5x-15)/(x^2 -4)
- e) z/(z-1)+1/2=3/z
- f) (x-3)/(x^2+2x-15)-(4-x)/(x^2-9x+20)
- 2. How do I set up this problem? An exam contains five "true or false" questions. How many of the 32 different ways of answering these questions contain 3 or more incorrect answers?
