Help me please cant figure it out<br> D;
Juli2301 [7.4K]

supplementary angles sum up to 180°, so let's say we have two angles, a and b, a + b = 180, but we know that a is <u>twice the measure of her partner</u>, so a = 2b.


\bf a+b=180\implies \stackrel{a}{2b}+b=180\implies 3b=180\implies b=\cfrac{180}{3} \\\\\\ \boxed{b=60}~\hspace{5em}a=2b\implies a=2(60)\implies \blacktriangleright a=120 \blacktriangleleft

Find and interpret the mean absolute deviation of the data. Round your answer to the nearest tenth, if necessary. Prices of micr
Gennadij [26K]

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

Therefore, the Mean Absolute Vale (MAD) is 4.4
