At a certain airport, 65% of the flights arrive on time. A sample of 10 flights is studied. Find the probability that all 10 of
babunello [35]

Answer:

So, the probability is P=0.0135.

Step-by-step explanation:

We know that at a certain airport, 65% of the flights arrive on time.

We get that p=0.65 and q=1-0.65=0.35.

We have 10 flights, so n=10.

We calculate the probability that all 10 of the flights were on time, so k=10.

We use the formulu:

\boxed{P(X=k)=C^n_k \cdot p^k\cdot q^{n-k}}

we get:

P(X=10)=C^{10}_{10}\cdot 0.65^{10}\cdot 0.35^0\\\\P(X=10)=1\cdot 0.0135\cdot 1\\\\P(X=10)=0.0135\\

So, the probability is P=0.0135.

First we need to write the factors of the polynomial. In order for 1, 4, and -3 to be roots, they need to be the x values that make the polynomial equal 0.

(x - 1) = 0

That would be the factor for x = 1 because when we plug 1 in for x we get 1 - 1 which equals 0.

Multiply all the factors together.

(x-1)(x-4)(x+3)=0

Now FOIL.

(x^2-5x+4)(x+3)

x^3-2x^2-11x+12
