If a quadratic equation has solutions, the standard procedure will always work: given an equation like

The solutions (if any) are given by

In your case, you have
So the formula becomes

Anyway, this is quite a special case, because you're missing the linear term (since
)
This means that you can solve equations like these more easily: rearrange the equation to make it look like
. In your case, it becomes

Divide both sides by 9:

Now, you know that the square of a number equals 1/9. By definition, it means that this number is the square root of 1/9. Nevertheless, both the square root and its opposite are solutions of the equation, because the minus sign will cancel out when squaring.
So, in general, you have

which of course makes sense, if you're using real numbers, only if c/a>0.
In your case, this becomes

It should be noted that a population means the entire group that a researcher wants to draw conclusions about.
<h3>What is a population?</h3>
Your information is incomplete s the data is not provided. Therefore, an overview will be given.
In statistics, a population refers to a set of similar items which is of interest for an experiment.
On the other hand, a sample is a set of individuals or objects that are selected from a statistical population through a defined procedure.
In this case, it is important to deduce if the sample represents the population.

Answer:
10% would be the answer
Step-by-step explanation:
Well, it would be 1+3 which is 4. Then 4+5 which is 9. Then 9+7 which is 16 so your final answer would be 16
