How can you use the mean absolute deviation of two<br> data sets to compare them?

Naddika [18.5K]

Answer:

The mean absolute deviation tells you how spread out or how clustered around the mean a set of data is. This is the variation in the data. To compare sets, a higher mean absolute deviation indicates that the data points are more spread out from the mean. A lower mean absolute deviation indicates data points are more clustered around the mean.

Find mZLKM.<br> м.<br> M<br> K/(3x – 70)<br> 60°<br> L<br> mZLKM=<br> l

Bingel [31]

Answer:

125

Step-by-step explanation:

( 3x - 70 ) is exterior angle.

60 and x are interior angles.

Formula : -

Exterior angle of a triangle

= Sum of two interior angles in a triangle

3x - 70 = x + 60

3x - x = 60 + 70

2x = 130

x = 130 / 2

x = 65

m∠LKM = 3x - 70

= 3 ( 65 ) - 70

= 195 - 70

m∠LKM = 125

What is the solution to this equation?<br> -1/5(x+1 1/4)=-2 1/2

lubasha [3.4K]

$\large\displaystyle\text{$\begin{gathered}\sf -\frac{1}{5}\left(x+1\frac{3}{4}\right)=-2\frac{1}{2} \end{gathered}$}$

Multiply both sides of the equation by 20, the lowest common denominator of 5,4,2.

$\large\displaystyle\text{$\begin{gathered}\sf \bf{-4\left(x+\frac{4+3}{4}\right)=-10(2\times2+1) } \end{gathered}$}$

Add 4 and 3 to get 7.

$\large\displaystyle\text{$\begin{gathered}\sf \bf{-4\left(x+\frac{7}{4}\right)=-10(2\times2+1) } \end{gathered}$}$

Use the distributive property to multiply −4 times x 4/7.

$\large\displaystyle\text{$\begin{gathered}\sf \bf{-4x-4\times\left(\frac{7}{4}\right)=-10(2\times2+1) } \end{gathered}$}$

Multiply −4 by 4/7.

$\large\displaystyle\text{$\begin{gathered}\sf \bf{-4x-7=10(2\times2+1) \ \ \to \ \ [Multiply \ 2\times2] } \end{gathered}$}$

$\large\displaystyle\text{$\begin{gathered}\sf \bf{-4x-7=10(4+1) \ \ \to \ \ [Add] } \end{gathered}$}$

$\large\displaystyle\text{$\begin{gathered}\sf \bf{-4x-7=10\times5 \ \ \to \ \ [Multiply] } \end{gathered}$}$

$\large\displaystyle\text{$\begin{gathered}\sf \bf{-4x-7=-50 } \end{gathered}$}$

Add 7 to both sides.

$\large\displaystyle\text{$\begin{gathered}\sf \bf{-4x=-50+7 \ \ \to \ \ [Add] } \end{gathered}$}$

$\large\displaystyle\text{$\begin{gathered}\sf \bf{-4x=-43 } \end{gathered}$}$

Divide both sides by −4.

$\large\displaystyle\text{$\begin{gathered}\sf \bf{x=\frac{-43}{-4} } \end{gathered}$}$

The fraction $\bf{\frac{-43}{-4}}$ can be simplified to $\bf{\frac{43}{4}}$ by removing the negative sign from the numerator and denominator.

$\large\displaystyle\text{$\begin{gathered}\sf \bf{x=\frac{43}{4} } \end{gathered}$}$

simplify

$\large\displaystyle\text{$\begin{gathered}\sf \bf{x=10\frac{3}{4} \ \ \to \ \ \ Answer } \end{gathered}$}$
