The mean absolute deviation of the scuba diver’s depth over the entire 25 min is 2.4 meters
<h3>What is mean absolute deviation?</h3>It is defined as the measure to show the variation in data set in other words between the mean and every data value, the distance known as the MAD.
We have depths of the scuba diver, in meters
{−9, −18, −16, −13, −14}
We know the formula for the mean absolute deviation:
Here n is total number of observation
x is the elements in the data set
X is the mean of the data.
n = 5
x = -70/5 = -14
∑|x-X| = 12
MAD = 12/5 = 2.4 meters
Thus, the mean absolute deviation of the scuba diver’s depth over the entire 25 min is 2.4 meters.

Answer:
Step-by-step explanation:
1) Circumference of cake = 25 1/7 inches
r = 4 inches
Area of cake = πr²
= 50.2857
= 50.29 in²
2) Area of square = side *side = 5 * 5 = 25 ft²
Diameter of semicircle = 5 ft
radius = 5/2 = 2.5 ft
Area of two semi circles = 2 * (1/2) πr² = πr²
= 3.14 * 2.5 *2.5
= 19.625
= 19.63 ft²
Area of the part of logo that still is green = 25 - 19.63
= 5.37 ft²
