Answer:
68%
Step-by-step explanation:
According to the empirical rule, 68% of the distribution lies within 1 standard deviation of the mean.
Here, the mean is 20 and the standard deviation is 5. The bounds on 1 standard deviation from the mean are 20±5 = [15, 25]. This is precisely the interval of interest.

Answer: 3 1/6 + 4 5/6 = 8 1/6.
Step-by-step explanation:
Let’s leave the whole numbers out for a second. You add 5/6 and 1/6 and that equals 1 or a whole. You add that to the whole numbers on the side of the fractions. So 3+4+1 =8. This is how the answer is 8 1/6.

Answer:
11
Step-by-step explanation:
58=2 x length + 2 x height.

The absolute value equation that represents the minimum and maximum scores is:
|x - 82| = 3.2.
<h3>What is the absolute value function?</h3>
The absolute value function is defined by:
It measures the distance of a point x to the origin.
For this problem, the distance between the minimum and the maximum scores and the mean is of 3.2, that is, the difference between these scores x and the mean of 82 is of 3.2, hence the absolute value equation that represents this situation is given by:
|x - 82| = 3.2.
