If a seed is planted, it has a 60% chance of growing into a healthy plant.

If 10 seeds are planted, what is the probability that exactly 1 doesn't grow? (round to 4 decimal places)

0.0016

Step-by-step explanation:

let p = growth probability = 60/100 = 0.6

q = probability of not growing = 1-0.6 = 0.4

Bernoulli equation is used to finish the probability

if exactly one grows, then 9 does not grow

That would be;

P(x = 1) = 10C1 p^1 q^9

= 10 * 0.6^1 * 0.4^9 = 0.001572864 = 0.0016 to 4 d.p

step-by-step explanation:

hello from mrbilldoesmath!

answer:   x (x+6)^2, choice b

discussion:

factor x out of the equation:

x^3 + 12x^2 + 36x = x (x^2 + 12x + 36).

note that 6+6 = 12 and 6*6 = 36 so the above factors into:

x (x+6)^2

which is choice b
