Answer:
The inequality that you have is
. You can use mathematical induction as follows:
Step-by-step explanation:
For
we have:


Hence, we have that 
Now suppose that the inequality holds for
and let's proof that the same holds for
. In fact,

Where the last inequality holds by the induction hypothesis.Then,




Then, the inequality is True whenever
.
Answer:
- The mean length of 10 children's big finger is 8.1 cm
Average length of all the 10 children's finger is (8.1×10) cm = 81 cm.
- The mean length of 11 adult's big finger is 14.1 cm
Average length of all the 11 adult's big finger is (14.1×11) cm =155.1
- Mean length of these 21 people's big finger is

- Hence, <em><u>11.24</u></em> is the right answer.
