OK, I'm retarded. Math isn't my bag. I should have paid more attention in class. But here I am and I need to know what 3e-8 means. A big number? A small number? I give up. (I will be happy if it's a small number though.)

More details: it's the probability of obtaining a SOBEL test result of 5.56668.

Thanks

For each quadratic function given below, find its vertex, axis of symmetry, y-intercept and x-intercept, if any. Determine the domain and range of each function. Determine where the functions are increasing and where they are decreasing.

(1) f(x) = x^2 - 4x

(2) f(x) = -3x^2 + 3x - 2

Hi.
I need help with the following as I can´t figure out how to get the answer. The textbook show the answer but I don´t know if it is right or how to get it.
Suppose x is a normally distributed random variable with u = 30 and o = 8. Find the random variable, call it a, such that:
P(x > a) = 0.1
Could you please explain each step so I can understand how this works?
How would I proceed if the problem was exactly the same except P(x < a) = 0.1
Thank you.
