Help. ;( Use the following dot plot to answer the questions. What is the mean of the set? If an additional dot is added to the set in the 3 column, how will the mean change? What will the new mean be?

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.

step-by-step explanation:

spinning a 1, 2, or 3. option d.

step-by-step explanation: when spinning a number graph up to 4, and aiming for any number less than 3, that automatically eliminates the number 4. now you have two numbers to spin on that are less than 3, but the number 3 is included in this question because it's no greater of an number than itself. i hope this you : )
