If population function x has mean M(x)=2 and M(x²)=8, find its standard deviation
1 answer:
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:

Substitute known values

Evaluate the expression

Step-by-step explanation:
Answer:
x - 6 m.
Step-by-step explanation:
x^2 - 4x - 12
= (x + 2)(x - 6)
So the width is x - 6 m.
Substitute in the values for y and x into the equation.
so..
8 - 4.7(-1) - (2) solve the equation
8 + 4.7 -2
12.7 - 2
