Total fish = 100
Carp = 30
Number of fish caught = 20
The random variable X follows hyper-geometric distribution.
Mean = 30 *20 / 100 = 600/100 = 6
Variance = 30*20/100 * ((20-1)*(30-1)/100-1 + 1-30*20/100)
Variance = 600/100 * 56/99
Variance = 112/33
Assumptions: Is that X follows hyper-geometric distribution with the given information.
(x-sqrt2)(x+sqrt2)(x+2) = (x^2 -2)(x+2) = x^3 +2x^2 -2x -4
hope helped
0.12r=1.8
Divide both sides by 0.12
r = 15
500 is what you already have if it grows 2.75% a month you multiply it by the month and add it to 500
500+2.75%m
