Answer:
9.73 cm to 2 DP
Step-by-step explanation:
Total of the lengths involved = 7*9.4 + 5*10.2
= 116.8 cm
So the mean of the 12 fingers
= 116.8/12
= 9.73 cm to 2 DP.

Unfortunately, there is no way I can find the value of X and Y because there is no question for it.
You can either find the value of X and Y in the problem or make X and Y your own value if you need to find something that is equivalent.
I hope this helped.
