Answer:
x < - 2
Step-by-step explanation:
given - 4.9x + 1.3 > 11.1 ( subtract 1.3 from both sides )
- 4.9x > 9.8 ( divide both sides by - 4.9 )
Remembering to reverse the direction of the inequality symbol as a result of dividing by a negative quantity.
x < - 2 ← inequality reversed
solution set : x ∈ ( - ∞, - 2 )
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:
Twenty-four and three hundred fifty-seven thousandths.
Step-by-step explanation:
The expanded form of 24.357 in decimals is 24.3757 because it is already in it's decimal form.

.
19 squares are or shaded so it’s 19%
