the deadly Ebola virus kills 85% of those who contract it. Of the next 100000 people who contract it, what is the mean number who will die?
 
Physics news on Phys.org
And your thoughts on the matter are___________?
 
I'm thinking it's:

85% of 100 000 which is 85 000 but I'm not really sure of that
 
Why not?
 
The mean is the "expected value". You are told that 85% die. Of 1000000 people, how many would you expect to die?
 
if it's 85% of 100 000 then 85 000 will die
 

Thread 'Prove that the integral is equal to ##\pi^2/8##'

Prove $$\int\limits_0^{\sqrt2/4}\frac{1}{\sqrt{x-x^2}}\arcsin\sqrt{\frac{(x-1)\left(x-1+x\sqrt{9-16x}\right)}{1-2x}} \, \mathrm dx = \frac{\pi^2}{8}.$$ Let $$I = \int\limits_0^{\sqrt 2 / 4}\frac{1}{\sqrt{x-x^2}}\arcsin\sqrt{\frac{(x-1)\left(x-1+x\sqrt{9-16x}\right)}{1-2x}} \, \mathrm dx. \tag{1}$$ The representation integral of ##\arcsin## is $$\arcsin u = \int\limits_{0}^{1} \frac{\mathrm dt}{\sqrt{1-t^2}}, \qquad 0 \leqslant u \leqslant 1.$$ Plugging identity above into ##(1)## with ##u...
