10. D If someone else wins, that means Jeff does not win. Thus, P(Jeff does not win) = 1-P(Jeff wins) = 1-0.2 = 0.8 20. I do not know what sample the problem is referring to. 12. C (40+30+20)/(15+25+40+30+20) = 0.69 13. C (15 + 40) / (130) = .42

If you have access to Microsoft Excel, paste in the points and plot the results. You'll see that it looks like a power function of the form y = b * m^x and handily enough Excel has a statistical function LOGEST that will get you b and m For this data b = 3.801271, m = 1.03605

"If the guy around-off blunders are UNIFORMLY distributed over (-0.5, 0.5)" skill that the sum of the rounded numbers would be precisely the sum of the numbers till now they're rounded. So the consequent sum will fluctuate by making use of the top sum by making use of 0. for this reason, the question is looking, "what's the prospect that 0 > 3?" So the respond is 0%. i'm hoping this facilitates!

"If the guy around-off blunders are UNIFORMLY dispensed over (-0.5, 0.5)" skill that the sum of the rounded numbers would be precisely the sum of the numbers in the past they're rounded. So the consequent sum will fluctuate via the right sum via 0. subsequently, the question is calling, "what's the possibility that 0 > 3?" So the respond is 0%. i wish this facilitates!

It is true for everyone, you are not alone. The reason I think is that when we answer others problems we are not emotionally attach to the problem, we look at it objectively and suggest really feasible answers. If others chose your answers as best and take your advice, it is proof that you are actually an intelligent and good human being. It is just that in case of your own problems, you are having another input: emotions. I have tries it in past, detach emotionally first and then think of the solution. If you can do it, you have the solution. If you can't, you ask others.

It's easy because you are able to lay aside the jumbled emotions and think rationally, whereas the person experiencing the problem has to deal with the emotions. When they're your own problems... you're the one dealing with the emotions. Even by answering THIS question, I somewhat prove my point. I too have no problem figuring out what someone else should do, but I always have to ask my friend's advice for my own problems. And they always have great answers. And I know that the same thing happens to me for the same reason it happens to you. But it still doesn't mean I can change that about myself. Neither can you, unless you learn to turn off your emotions, and that's really not what you're after at all, is it?
