The arithmetic mean of five numbers is 2.4. And the arithmetic mean of the other three numbers is 3.2. Find the arithmetic mean of these eight numbers.
Let’s find the sum of the arithmetic mean of five numbers 2.4 and the arithmetic mean of three other numbers, as a result we get the arithmetic mean of two values:
2.4 + 3.2 = 5.6.
In order to find the arithmetic mean of eight numbers, after adding the two arithmetic means of these numbers, divide them by two, as a result we get the arithmetic mean of the two arithmetic means or the arithmetic mean of eight numbers:
5.6: 2 = 2.8 is the arithmetic mean of eight numbers.
Answer: 2.8 is the arithmetic mean of eight numbers.
