What is the definition of arithmetic mean?
It is the sum of all of the numbers, divided by the number of numbers. For example, what is the arithmetic mean of this set of numbers: 8, 6, 4, 2 ? Add up the numbers: 8+6+4+2=20. The number of numbers is 4; so divide 20 by 4 to get 5, which is the arithmetic mean.
What is the Relation between geometric mean and arithmetic mean?
The mean of the numbers a1, a2, a3, ..., an is equal to (a1 + a2 + a3 +... + an)/n. This number is also called the average or the arithmetic mean.The geometric mean of the positive numbers a1, a2, a3, ... an is the n-th roots of [(a1)(a2)(a3)...(an)]Given two positive numbers a and b, suppose that a< b. The arithmetic mean, m, is then equal to (1/2)(a + b), and, a, m, b is an arithmetic sequence. The geometric mean, g, is the square root of ab, and, a, g, b is a geometric sequence. For example, the arithmetic mean of 4 and 25 is 14.5 [(1/2)(4 + 25)], and arithmetic sequence is 4, 14.5, 25. The geometric mean of 4 and 25 is 10 (the square root of 100), and the geometric sequence is 4, 10, 25.It is a theorem of elementary algebra that, for any positive numbers a1, a2, a3, ..., an, the arithmetic mean is greater than or equal to the geometric mean. That is:(1/n)(a1, a2, a3, ..., an) ≥ n-th roots of [(a1)(a2)(a3)...(an)]
What is the mean of 4 9 7 4 1?
The mean is the arithmetic average. The average of 4 9 7 4 & 1 is 5
What is the mean of 0 1 2 3 4?
