Answer: D

Step-by-step explanation: You just have to take the equation in the question and simplify it. -2 x y = -2y, -2 x -8 = +16, so -2y + 16, then on the other side add 10 to 15 15+10=25, and then keep the -y, so finally the final equation/inequality is -2y + 16 <u><</u> 25 - y.

Answer:

<h2>The Mean Absolute Vale (MAD) is 4.4</h2>

Step-by-step explanation:

The mean absolute deviation is defined as

$MAD=\frac{\sum |x_{i}-\mu |}{N}$

Where $\mu$ is the mean and $N$ is the total number of data.

The means is defined as

$\mu = \frac{\sum x_{i} }{N}=\frac{25+28+20+22+32+28+35+34+30+36}{10}=\frac{290}{10}=29$

And, $N=10$

Replacing these values, in the MAD formula, we have

$MAD=\frac{|25-29|+|28-29|+|20-29|+|22-29|+|32-29|+|28-29|+|35-29|+|34-29|+|30-29|+|36-29|}{10} \\MAD=\frac{|-4|+|-1|+|-9|+|-7|+|3|+|-1|+|6|+|5|+|1|+|7|}{10}=\frac{44}{10}\\ MAD = 4.4$
