If you would like to calculate the arithmetic mean, geometric mean, and harmonic mean from the following averages, you can calculate this using the following steps:
averages: 56.4, 59.8, 55.8
the number of values: 3
arithmetic mean:
(56.4 + 59.8 + 55.8) / 3 = 57.33
geometric mean:
(56.4 * 59.8 * 55.8)^(1/3) = 57.31
harmonic mean:
3 / (1/56.4 + 1/59.8 + 1/55.8) = 57.28
First round
137,638=100,000
52,091=50,000
Then add to get the estamate
100,000
+
50,000
150,000
Then to get the real answer add
1
137,638
+
52091
189,729
Answer:
4
Step-by-step explanation:
<em>1 3/5(2/5) = 4</em>
I'm fairly certain the answer is 1/3.
