Answer:

Step-by-step explanation:

You are combining like terms.

1.) find all of the #x³ and there is only one and that is -x³ so that limits the problem to B or D.

2.) now you find all of the #x² and there are three of them being 10x², -x², and 4x². Now that you have identified them you will add them together to get a sum of 13x²

you don't have to do anymore of the question because D does not have 13x² so it is B.

Answer:

The probability that there are 8 occurrences in ten minutes is

option B. 0 .0771

Step-by-step explanation:

Given:

Random Variable = x

Mean number of occurrences in ten minutes is 5.3.

The probability of an occurrence is the same in any two time periods of an equal length

To Find:

The probability that there are 8 occurrences in ten minutes = ?

Solution:

Let X be the number of occurrences of the event X

$X \sim {Pois} (\lambda)$

$\lambda = E(X) = 5.3$

Possion of distribution is given by ,

$P(X=x) = \frac{e^{- \lambda} \lambda^{x}}{x!}$

Substituting the values,

$P(X=8) = \frac{e^{- 5.3} 5.3^{8}}{8!}$

$P(X=8) = \frac{(0.004994) ( 622596.904)}{40320}$

$P(X=8) = \frac{(3109.24894)}{40320}$

P(X=8) = 0.0771
