What is the mean of the following data set?<br>

If I'm not mistaken you add the numbers up, then you divide it by the amount of numbers there. 4 + 5 + 2 + 4 + 9 + 7 + 5 + 5 + 2 + 8 = 51

51 / the amount of numbers there (10) = 5.1

Hope this helps :)

**Move the center of circle A to (1,7), then multiply its radius by 3.**

**Step-by-step explanation:**

Moving the circles to the same center would make them concentric. Then, by multiplying the radius of Circle A by 3, the circle is dilated to the exact size of circle B, since its radius is 9. This shows that Circle B is proportional to Circle A, thus they are similar.

**Answer:**

Your wrong, it’s B.
