The absolute value equation for the scores within one standard deviation of the mean is:
|x - 20.9| = 5.3.
The minimum score that is within one standard deviation of the mean is of 15.6.
<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 of x = 0.
One standard deviation is of 5.3, while the mean is of 20.9, hence the absolute value equation for the scores within one standard deviation of the mean is:
|x - 20.9| = 5.3.
Which means that the minimum score is:
x - 20.9 = -5.3
x = 15.6.

Step-by-step explanation:
length = 2×width + 6
84 = 2×length + 2×width
now using the first in the second equation :
84 = 2×(2×width + 6) + 2×width = 4×width + 12 + 2×width
84 = 6×width + 12
72 = 6×width
width = 12 cm
length = 2×width + 6 = 2×12 + 6 = 24 + 6 = 30 cm

Nonlinear
Step-by-step explanation:
Answer:
0.76 or 19/25
Step-by-step explanation:
Convert 4/10 so that it has a common denominator with 36/100.
4/10 x 10/10 = 40/100
Now that the denominator is the same, just add the top values.
40/100 + 36/100 = 76/100
We can also simplify the answer to be 19/25 by dividing the top and bottom by 4.
