Answer:

1.) 3.18

2.)3.375 (not rounded)

Step-by-step explanation:

To find the mean, you need to count the total value of the dots and divide that number by the amount of dots. For example: The value of the dots is 51, and the amount of dots is 16. So 51/16=3.18. This also applies to adding an extra dot in the 3's column. So 51+3=54. 54/17=3.176.
