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.

7.5/2=2.5
for how many digits is rounding required to occur?
if it's one digit, it should be 70,000 and 20,000
if it's two digits it would be 75,000 and 23,000
if it's three digits it would be 74,700 and 22,900
if it's four digits it would be 74,710 and 22,980
The answer is B because 2/8= 1/4.
