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
Answer:
8/10
Step-by-step explanation:
add the numerator but keep the denominators the same
you could also simplify to 4/5
Answer:
8
Step-by-step explanation:
Solve for x:
x - 8 = 0
Hint: | Isolate terms with x to the left hand side.
Add 8 to both sides:
x + (8 - 8) = 8
Hint: | Look for the difference of two identical terms.
8 - 8 = 0:
Answer: x = 8
