Yes they are 
When a research question asks you to find a statistical sample mean (or average), you need to report a margin of error, or MOE, for the sample mean. The general formula for the margin of error for the sample mean is the population standard deviation, n is the sample size, and z* is the appropriate z*<span>-value for your desired level of confidence

</span>1.Find the population standard deviation and the sample size, n<span>.
</span><span>2.Divide the population standard deviation by the square root of the sample size.
</span>3.Multiply by the appropriate z*<span>-value.

A perfect square trinomial can be represented by a square model with equivalent length and width. Which polynomial can be repres
lina2011 [118]
The correct answer is 
A) x^2 - 6x + 9

In fact, this is a trinomial of the form ax^2-bx+c, whose solutions are given by
x_{1,2}=  \frac{-b\pm \sqrt{b^2 -4ac} }{2a}
Using this formula for the trinomial of the problem, we find:
x1,2=  \frac{6 \pm \sqrt{6^2-4\cdot 1\cdot 9}}{2} =3
<span>we see that this trinomial has two coincident solutions (x=3 with multiplicity 2). This means that it can be rewritten as a perfect square, in the following form: 
</span>(x-3)^2<span>
