Answer:
By the Empirical Rule,
Step-by-step explanation:
The Empirical Rule states that, for a normally distributed random variable:
68% of the measures are within 1 standard deviation of the mean.
95% of the measures are within 2 standard deviation of the mean.
99.7% of the measures are within 3 standard deviations of the mean.
The symbol of a standard deviation is . So
When plotting sample statistics on a control chart, 99.7% of the sample statistic values are expected to fall within plus/minus how many sigma?
By the Empirical Rule,
Answer:
6
Step-by-step explanation:
- 6x +5 = 0
- 6x + 9 -9 +5 = 0
[ - 6x + 9] - 4 =0
-4 = 0
= 4
(x-3) = or (x-3) = -
(x-3) = 2 or (x-3) = -2
x = 5 or x = 1
therefore, sum of these solutions is 5+1 = 6
