Answer:

(x+3)^2

Step-by-step explanation:

You have the equation and you want to put as a root so x squared plus 6x minus 9 as a root equals (x+3) squared. If you multiply x+3 by x+3 you will get the original equation.

lysha is at a local library with her best friend. they've noticed a lot of cute boys in the library, and alysha bets that of the
Annette [7]

Using the binomial distribution, there is a 0.1201 = 12.01% probability that Alysha will win the bet.

<h3>What is the binomial distribution formula?</h3>

The formula is:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

C_{n,x} = \frac{n!}{x!(n-x)!}

The parameters are:

  • x is the number of successes.
  • n is the number of trials.
  • p is the probability of a success on a single trial.

For this problem, the parameters are given as follows:

n = 20, p = 0.5.

She wins the bet if there are 12 boys, hence the probability is P(X = 12), found as follows:

P(X = x) = C_{n,x}.p^{x}.(1-p)^{n-x}

P(X = 12) = C_{20,12}.(0.5)^{12}.(0.5)^{8} = 0.1201

0.1201 = 12.01% probability that Alysha will win the bet.
