Answer:
Herman's final position is -3 feet relative to the ground level.
Step-by-step explanation:
As given:
Herman starts out on a rung that is 6 feet under ground ,climbs up 14 feet,then climbs down 11 feet.
The initial position is 6 feet(negative value) under ground, then up 14 feet (plus value)and down again 11 feet(negative value).
We take positive value when position is above the initial level and negative when the position is below the level.
The final position relative to ground level is:
=
Therefore, Herman's final position is -3 feet relative to the ground level.

The mean absolute deviation for the number of hours students practiced the violin is 6.4.
<h3>What is the mean absolute deviation?</h3>
The average absolute deviation of the collected data set is the average of absolute deviations from a center point of the data set.
Given
Students reported practicing violin during the last semester for 45, 38, 52, 58, and 42 hours.
The given data set is;
45, 38, 52, 58, 42
Mean Deviation = Σ|x − μ|/N.
μ = mean, and N = total number of values
|x − μ| = |45 − 47| = 2
|38− 47| = 9
|52− 47| = 5
|58− 47| = 11
|42− 47| = 5
The mean absolute deviation for the number of hours students practiced the violin is;
Hence, the mean absolute deviation for the number of hours students practiced the violin is 6.4.
