1) from smaller to higher:
1,5,11,11,17
2) find the mean
<span>1 + 5 + 11 + 11 + 17 = </span><span>45
</span>mean = 45/5 = 9
Variance = Σ(x- mean)²/(N-1)
[(1-9)² + (5-9)²+(11-9)² + (11-9)²+ (17-9)² ]'(5-1) = 38
Variance = 38
You already know that the quetioent of 1/2 divided by 6 would be more or less than one because, 1/2 is equal to 50% and 50% of 6 is 3. So, you would know how the answer would turn out.
Factorization involves representing an expression with smaller terms.
- <em>When the greatest common factor is factored out, the equivalent expression is: </em>
<em>.</em> - <em>The complete factored expression is: </em>
<em />
The expression is given as:

The GCF of
and
is
.
So, we have:

Factor out 

To factorize the expression completely, we express
and
as squares.
So, we have:

Apply difference of two squares

So, the complete factor of
is
