Find the value of X.

klemol [59]

Answer:

I think answer is 3

Step-by-step explanation:

BD = DA

BE = EC

Now, BD/BE = DA/EC

or, x + 5/2x = 4/3

or, 3x + 15 = 8x

or, 15 = 8x - 3x

or, 15 = 5x

or, 15/5 = x

or, 3 = x

Therefore x = 3 <u>Ans</u>

Factorize completely <br> 81k^2 - m^2

Genrish500 [490]

81k^2 - m^2 factors to

(9k + m)(9k - m)

Prove this by FOILing.

First - 81k^2

Outer - (-9km)

Inner - 9km

Last - (-m^2)

Put it into equation form

81k^2 - 9km + 9km - m^2

And combine terms to get the original equation,

81k^2 - m^2.

Answer:

$P(X > 0) = 0.9222$

Step-by-step explanation:

For each name, there are only two outcomes. Either the name is authentic, or it is not. So, we can solve this problem using the binomial probability distribution.

Binomial probability distribution

The binomial probability is the probability of exactly x successes on n repeated trials, and X can only have two outcomes.

$P(X = x) = C_{n,x}.\pi^{x}.(1-\pi)^{n-x}$

In which $C_{n,x}$ is the number of different combinatios of x objects from a set of n elements, given by the following formula.

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

And $\pi$ is the probability of X happening.

In this problem.

5 names are selected, so $n = 5$

A success is a name being non-authentic. 40% of the names are non-authentic, so $\pi = 0.40$ .

We have to find $P(X > 0)$

Either the number of non-authentic names is 0, or is greater than 0. The sum of these probabilities is decimal 1. So:

$P(X = 0) + P(X > 0) = 1$

$P(X > 0) = 1 - P(X = 0)$

$P(X = x) = C_{n,x}.\pi^{x}.(1-\pi)^{n-x}$

$P(X = 0) = C_{5,0}*(0.40)^{0}*(0.6)^{5} = 0.0778$

So

$P(X > 0) = 1 - P(X = 0) = 1-0.0778 = 0.9222$
