Answer:

Step-by-step explanation:

This a special right triangle with angle measures of 30° 60° 90°

The side length that sees angle measure 30° is represented with a, the one that sees 90° is represented by 2a and the one that sees 60° is represented by a√2

AC sees angle B which has an angle measure of 60

(6√2)×(√2) = 24

Is the mistake one two three or is their no mistake

maria [59]

Answer:

the mistake is that to "remove" the 1/2 on the left you would have to multiply by 2 (or divide by 1/2 but no one does that)

the result would be that 2h-4 = 10 should actually be 2h-4 = 20

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
