3p . (2+k) = 6p + 3pk

pashok25 [27]

$3p* (2+k) = 6p + 3pk$

Subtract $6 p + 3 pk$ from the both sides:

$3p(2+k) -(6p+3pk) = 6p+3pk-(6p+3pk)$

$= 3pk(2+k) - 6p-3pk = 0$

Factor $3p(2+k) - 6p - 3k$

Factor out common term $3p$

$= 3p(k-k+2-2)$

refine:

$0 = 0$

true for all $p$

hope this helps!

Find the variance of the following data. Round your answer to one decimal place. x 1 2 3 4 5 P(X=x) 0.3 0.2 0.2 0.1 0.2

Reptile [31]

The variance of a distribution is the square of the standard deviation

The variance of the data is 2.2

<h3>How to calculate the variance</h3>

Start by calculating the expected value using:

$E(x) = \sum x* P(x)$

So, we have:

$E(x) = 1 * 0.3 + 2* 0.2 +3 * 0.2 + 4 * 0.1 + 5 * 0.2$

This gives

$E(x) = 2.7$

Next, calculate E(x^2) using:

$E(x^2) = \sum x^2* P(x)$

So, we have:

$E(x^2) = 1^2 * 0.3 + 2^2* 0.2 +3^2 * 0.2 + 4^2 * 0.1 + 5^2 * 0.2$

$E(x^2) = 9.5$

The variance is then calculated as:

$Var(x) = E(x^2) - (E(x))^2$

So, we have:

$Var(x) = 9.5 - 2.7^2$

$Var(x) = 2.21$

Approximate

$Var(x) = 2.2$

Hence, the variance of the data is 2.2
