Answer:

The correct answer is D. x = 11.1

Step-by-step explanation:

The two chords in the circle are intersecting with each other and are divided into two sub parts.

By Chord intersection theorem we have : If the two chords intersect with each other then the product of their corresponding sub parts is equal.

So, to find x :

⇒ 26 × 6 = x × 14

⇒ 14·x = 156

⇒ x = 11.1 units

Therefore, The correct answer is D. x = 11.1

Find the mean, variance, and standard deviation of the binomial distribution with the given values of n and p. , The mean, ,

Complete Question

Find the mean, variance, and standard deviation of the binomial distribution with the given values of n and p. , The mean, , is nothing. (Round to the nearest tenth as needed.)

p = 0.6 n = 18

Answer:

The mean $\mu = 10.5$

The standard deviation $\sigma = 2.08$

The variance $var = 4.32$

Step-by-step explanation:

From the question we are told that

The probability of success is $p = 0.6$

The sample size is $n = 18$

Generally given that the distribution is binomial, then the probability of failure is mathematically represented as

$q = 1- p$

substituting values

$q = 1- 0.6$

$q =0.4$

Generally the mean is mathematically evaluated as

$\mu = np$

substituting values

$\mu = 18 * 0.6$

$\mu = 10.5$

The standard deviation is evaluated as

$\sigma = \sqrt{npq}$

substituting values

$\sigma = \sqrt{18 * 0.6 * 0.4}$

$\sigma = 2.08$

The variance is evaluated as

$var = \sigma^2$

substituting value

$var = 2.08^2$

$var = 4.32$
