Answer:
True.
Step-by-step explanation:
The <em>empirical rule </em>states that for a bell shaped distribution, nearly all of the data will fall within three standard deviations of the mean.
<em>Chebyshev’s inequality </em>says that at least
of data from a sample will fall within
standard deviations from the mean.
We have to remember that Chebyshev’s inequality has been proven mathematically for any distribution. But the empirical rule is a tool created for bell shaped distributions.
1/2+3/x = 3/4
3/x = 3/4 - 1/2
3/x = 3/4 - 2/4
3/x = 1/4
12 = x
the denominator are not 0 and still can solve it with a value of 12
