To find the mean is to find the average, which means add all the data values together and divide by the number of data values. In this case, we add those values together and divide by 6, which equals 82.5/6= 13.75

What number sentence is true?

meriva

D would be true because if you think about it in percentage wise
2/8= 25%
2/3=66.66%
2/3 is automatically greater than 2/8
Hope this helps :)
