Step-by-step explanation:

mean; 8+6+4+7+3y+5/6=6

         30+3y/6=6

cross multiply; 30+3y=36

                          3y=36-30

                        3y=6

                       y=2

3y=2x3

3y=6

Answer 2

Answer:

8

Step-by-step explanation:

Given:-

mean of 8,6,4,7,3y and 5=6

To Find:-

y³

Formula Applied:-

Mean=Sum of all the values/Total Number of Values

Solution:-

(8+6+4+7+3y+5)/6=6

30+3y=36

3(10+y)=36

10+y=36/3

10+y=12

y=12-10

y=2

⇒y³=(2)³=8
