Answer:
The mean length of the 13 people's big finger is 15.45 cm
Step-by-step explanation:
Given;
mean length of 4 childrens' big finger, x' = 14cm
mean length of 9 adults' big finger is 16.1cm, x'' = 16.1cm
Let the total length of the 4 childrens' big finger = t

Let the total length of the 9 adults' big finger = T

The total length of the 13 people's big finger = t + T
= 56 + 144.9
=200.9 cm
The mean length of these 13 people's big finger;
x''' = (200.9) / 13
x''' = 15.4539 cm
x''' = 15.45 cm (2 DP)
Therefore, the mean length of the 13 people's big finger is 15.45 cm
What you have to do first is put them both into improper fractions first. 4 1/6 would be 4 time 6 plus 1 which equals 25/6. Next 1 5/6 would be 1 times 6 plus 5 which equals 11/6. Next what you have to do is subtract 25-6 which equals 19. Next you put 19/6. Two ways to answer is to leave it improper or as a mix number. Answer for improper fraction is 19/6. The other way for a mix number is 3 1/6.
