Gala2k [10]3 years ago
8 0

Answer: x=8 and x=-8

Step-by-step explanation:

To find the solutions of the quadratic equation, you want to factor it and set it equal to 0.

x²-16=0

(x+8)(x-8)=0

x+8=0

<u>x=-8</u>

x-8=0

<u>x=8</u>

Now that we have factored and set the factors equal to 0, we found that the solutions are x=-8 and x=8.

N = number of seeds planted

P = probability of germination

K = number that germinated

Using probability calculation:
p(x = k) = (n k) x 0.90^K x 0.10^n-k


p(10) = (12 10) x 0.90^10 x 0.10^2

P(10) = 0.2310
