For this case we have the following equation:
From here, we must clear the value of x.
For this, we follow the following steps:
1) Place the variable on one side of the equation and the constant on the other side of the equation:
2) Make common factor x:
3) Clear the value of x:
Answer:
The relationship between x and the difference of a - b is inversely proportional.
Answer:
__
0.2676 or 0.268
Step-by-step explanation:
53 ÷198
Using the Empirical Rule, it is found that the proportion of people in a population with IQ scores between 80 and 140 is of 0.95 = 95%.
<h3>What does the Empirical Rule state?</h3>
It states that, for a normally distributed random variable:
- Approximately 68% of the measures are within 1 standard deviation of the mean.
- Approximately 95% of the measures are within 2 standard deviations of the mean.
- Approximately 99.7% of the measures are within 3 standard deviations of the mean.
Considering the mean of 110 and the standard deviation of 15, we have that:
These values are both the most extreme within 2 standard deviations of the mean, hence the proportion of people in a population with IQ scores between 80 and 140 is of 0.95 = 95%.
