Firstly, we have to find the mean. The mean is simply the average of the numbers, which we find by adding each number in the sequence and then dividing that result by the total amount of numbers.

<em>13.3 + 14.3 + 15.3 + 16.3 + 17.3 = 76.5</em>

<em>76.5 / 5 = 15.3

</em>Okay, so our average is 15.3.
<em>
Now, </em>we have to subtract the mean from each number and then square the result.

<em>(13.3 - 15.3)^2 = 4</em>
<em>(14.3 - 15.3)^2 = 1</em>
<em>(15.3 - 15.3)^2 = 0</em>
<em>(16.3 - 15.3)^2 = 1</em>
<em>(17.3 - 15.3)^2 = 4

</em>Now we have to find the mean of those numbers!
<em>
4 + 1 + 0 + 1 + 4 = 10

10 / 2 = 2

</em>Finally, we take the square root of that number and we have our standard deviation. =)<em>

Answer:

Infinite Solutions

Step-by-step explanation:

If you distribute the left side of the expression, you will get 3y -32, which is exactly the same as the right side of the equation. Since both lines are the same, that means that they have an infinite amount of solutions. Therefore, the 4th choice is correct.
