That would be the square root of 60, approximately 7.7. Because 3/7.7 is (close to) 7.7/60.
It is sqrt(20) = 4.4721, approx.
sqrt(6*10) = sqrt(60) = 7.75 (approx)
No, the geometric mean is not the same as the mean of two numbers.
The geometric mean of 9 and 25 is: 15.0
The geometric mean of 10 and 20 is 14.1421356237
That would be the square root of 60, approximately 7.7. Because 3/7.7 is (close to) 7.7/60.
Geometric mean of 6 and 20 = sqrt(6*20) = sqrt(120) = 10.95445
What is the sum of the first 27 terms of the geometric sequence -3, 3, - 3, 3, . . . ?
Geometric mean = sqrt(5*80) = sqrt(400) = 20
it is 10
22.36068
Geometric mean of two numbers is the square root of their product so sqrt(8*50) = sqrt(400) = 20
To find a geometric mean, we multiply all of the terms together and take the nth root of the result (where n is the number of terms we are averaging). With 10 and 6, we find the geometric mean is the square root of 10*6 = 60. Sqrt(60) = 2*sqrt(15).
Arithmetic mean = (60+85)/2 = 145/2 = 72.5 Geometric mean = sqrt(60*85) = 71.41 approx.
GM(4, 60) = sqrt(4*60) = 4*sqrt(15) = 15.492 approx
It is approx 16.73
