100 / [1 + e^(2x)] = 1. x = ? (5 points)
Hint: One simple - although non-standard - way to do it: notice that e^(2x) = 99.
-/5 POINTS MINTROSTAT9 7.E.521.XP. MY NOTES ASK YOUR TEACHER A simple random sample of 100 postal employees is used to test if the average time postal employees have worked for the postal service has changed from the value of 7.5 years recorded 20 years ago. The sample mean was 7 years with a standard deviation of 2 years. Assume the distribution of the time the employees have worked for the postal service is approximately normal. The hypotheses being tested are...

List all points (x,y) in the elliptic curve y2≡ x3 + 2x - 9 (mod 19). (Hint: Corresponding to any given x , points (x,y) and (x,-y) can exist on the elliptic curve only if y2≡ x3 + 2x - 9 (mod 19) is a quadratic residue mod 19. Recall that a value v ∊ Zp is a quadratic residue modulo p only if v(p-1)/2≡ 1 (mod p). If v is indeed a quadratic residue, we can calculate the two...
