<span>We have the following polynomial:

The problem states that one root is -3. Thus, it is true that

is a factor of the polynomial. Given that this is fulfilled, it is also true that:
</span>

We can find Q(x) by applying Ruffini's rule, thus:
</span>

<span>
Therefore:
The roots of this polynomial can be get as follows:
These are the roots along with

. Finally, the factored polynomial can be written as follows:

Answer:
C
Step-by-step explanation:
In this question, we are asked to calculate the interquartile range of the speed values given in the question.
Firstly, we need to order the values of the speed from the lowest to the highest. That would be;
55 58 65 66 70 72 81
Now, we determine the first quartile position which is Q1. That would be (N+1)/2 where N is the number of data points which is 7 according to this question
We have (7 +1)/4= 8/4= 2
The value at the 2nd position counting from left is 58
For the third quartile , Q3, we have 3 * (N+1)/4 = 3 * 2 = 6
The value at the 6th position counting from left is 72
mathematically, the formula for the interquartile range is Q3 - Q1 = 72 - 58 = 14
In order to calculate this, you need to solve :

x 100 %
= 0.2 / 9.87 x 100 %
= 2.02 %

It's the same amount each month, for a year. So:
total money ÷ times money was taken out= how much has been taken out.
$600÷12=50
