The average (mean) absolute deviation of a data set is the average of the absolute deviations from a central point.

so we need to calculate the mean of this data set firstly:::
the mean of (7,10,19,14,3) = \frac{7+10+19+14+3}{5} =10.6

then we will calculate how far each record is from this mean:::
7-10.6 = - 3.6
10-10.6 = - 0.6
19-10.6 = 8.4
14-10.6 = 3.4
3-10.6 = - 7.6


BUT as it requires the ABSOLUTE mean deviation, we will take the absolute values of the previous results

3.6  &    0.6  &    8.4  &    3.4  &    7.6

Adding them together and divide by the records number (5)::

ABSOLUTE mean deviation = \frac{3.6+0.6+8.4+3.4+7.6}{5} =4.72


Done!!!



I hope you got the idea

Create your own real-world example of a relation that is a function. Domain: The set of Range: The set of
ivanzaharov [21]

Answer:

C(t)=5000 -10t

Step-by-step explanation:

There are many examples in the real world of relationships that are functions.

For example, imagine a tank full of water with a capacity of 5000 liters, this tank has a small hole, by which 10 liters of water are lost every hour.

If we call C the amount of water in the tank as a function of time, then we can write the following equation for C:

C(t)=C_{0}-at\\

Where:

C (t): Amount of water in the tank as a function of time

C_{0}: Initial amount of water in the tank at time t = 0

a: amount of water lost per hour

t: time in hours

Then the equation is:

C(t)=5000 -10t

The graph of C (t) is a line of negative slope. This relation is a function since for each value of t there is a single value of C.

Its domain is the set of all positive real numbers t between [0,500]

Because the time count starts at t = 0 when the tank is full and ends at t = 500 when empty

Its Range is the set of all positive real numbers C between [0,5000] Because the amount of water in the tank can never be less than zero or greater than 5000Litres

Find the measure of each angle (in degrees) of
d1i1m1o1n [39]

Answer:

∠A = 88°

∠B = 92°

∠C = 88°

∠D = 92°

Step-by-step explanation:

∠A + ∠B = 180°

(2x + 4) + (3x - 34) = 180

reduce:

5x - 30 = 180

5x = 210

x = 42

∠A = 2(42) + 4 = 88°

∠B = 3(42) -34 = 92°

∠C = ∠A = 88°

∠D = ∠B = 92°
