Answer:
Mean age = 1271.27
Step-by-step explanation:
No of children = 77
The age at which children first began to combine words = 16.51 months
Mean age = No of children × age at which children first began to combine words
= 77 × 16.51
= 1271.27
Mean age = 1271.27

Answer:
$541.22
Step-by-step explanation:
We are given;
Amount deposited (principal) is $500
Rate of interest is 4%
Time = 2 years
We are required to determine amount in the account after 2 years
Interest periods, n = 4 (since the money was compounded semi-annually)
rate of interest, r = 2%
Using the compound interest formula;
Amount, A = P (1 + r/100)^n
Therefore;
Amount = $500 (1 + 2/100)^4
= $500 × 1.02^4
= $541.22
Therefore, the balance in the account after 2 years is $541.22
The sum of the first n natural number = n * (n+1) / 2, for n a natural number.
