-5x + 12 - 7x = -3(5x + 8)

nikitadnepr [17]

Simplify -5x + 12 - 7x to -12x + 12

-12x + 12 = -3(5x + 8)

Expand

-12x + 12 = -15x - 24

Add 15x to both sides

-12x + 12 + 15x = -24

Simplify 12x + 12 + 15x to 3x + 12

3x + 12 = -24

Subtract 12 from both sides

3x = -24 - 12

Simplify -24 - 12 to -36

3x = -36

Divide both sides by 3

x = -36/3

Simplify 36/3 to 12

Suppose that X is a random variable that has a binomial uncertainty distribution with parameters n = 10 and π = 0.4. Calculate t

swat32

The numerical values of the mean and standard deviation are 4 and 1.55, respectively

<h3>The numerical value of the probability that x = 6. </h3>

The given parameters are:

n = 10

π = 0.4

The probability is then calculated as:

$P(x) = ^nC_x * \pi^x *(1-\pi)^{n-x}$

So, we have:

$P(6) = ^{10}C_6 * 0.4^6 *(1-0.4)^4$

Apply the combination formula

$P(6) = \frac{10!}{6!4!} * 0.4^6 *0.6^4$

So, we have:

$P(6) = 210 * 0.4^6 *0.6^4$

Evaluate

P(6) = 0.1115

Hence, the numerical value of the probability that x = 6 is 0.1115

<h3>The numerical values of the mean and standard deviation </h3>

The mean value is:

$\bar x = n\pi$

This gives

$\bar x = 10 * 0.4$

$\bar x = 4$

The standard deviation value is:

$\sigma = \sqrt{\bar x(1-\pi)$

This gives

$\sigma = \sqrt{4(1-0.4)$

$\sigma = 1.55$

Hence, the numerical values of the mean and standard deviation are 4 and 1.55, respectively
