The standard deviation of the population function is 2

<h3>How to determine the standard deviation?</h3>

The given parameters are:

M(x) = 2

M(x²)=8

The standard deviation is calculated using:

\sigma = \sqrt{M(x^2) - (M(x))^2

Substitute known values

\sigma = \sqrt{8 - 2^2

Evaluate the expression

\sigma = 2

Hence, the standard deviation of the population function is 2

Clara found the product of 3 – 6y2 and y2 + 2. Her work is shown below. (3 – 6y2)(y2 + 2) = 3(y2) + (–6y2)(2) = 3y2 – 12y2 = –9y
Lilit [14]
No he's not correct

<span>(3 – 6y2)(y2 + 2)  
= 3(y2) -6(y2)(y2)  - 6y2(2) </span>+ 3(2)<span>
= 3y2 -6y4 - 12y2 </span>+ 6 <span>
= -6y4 - 9y2 +6</span>
