Find the geometric mean between 28 and 32. Round to the nearest tenth if necessary.
Answer: The geometric mean is √24 * 32 = √768 = 16√3.
The geometric mean between 28 and 32 is 28.29 after using the formula of the geometric mean.
What is mean?
It is defined as the single number that represents the mean value for the given set of data or the closed value for each entry given in the set of data.
Let x be the geometric mean between 28 and 32
The formula for the geometric mean:
x = √(a×b)
x = √(28×32)
x = √800
x = 20√2
x = 28.284
or
x = 28.29
Thus, the geometric mean between 28 and 32 is 28.29 after using the formula of the geometric mean.
