A binomial probability has p=.20 and n=100, what are the mean and standard deviation?

1 answer:

4 0

Mean: $np=100\times0.20=20$

Standard deviation: $\sqrt{np(1-p)}=\sqrt{100\times0.20\times0.80}=4$

To find the side lengths, you have to factor 4x^2 + 28x + 49. This equation factored is (2x+7)(2x+7), so each side length is (2x+7) feet.

Y=kx+b
2k+b=-1
6k+b=1
6k+b-2k-b=2
4k=2
k=1/2
b=-2
y=1/2x-2
So your answer is option A
