$1)~-8x-(8x)=-48\iff -16x=-48\iff 16x=48\iff\\\\\x=\dfrac{48}{16}\iff \boxed{x=3}$

$2)~y-y_p=m(x-x_p)\Longrightarrow\boxed{y-3=-2(x-2)}$

<h3>Sin $\theta_{1}=\frac{3\sqrt{21}}{17}$ </h3>

Solution given:

Cos $\theta_{1}=\frac{10}{17}$

$\frac{adjacent}{hypotenuse}=\frac{10}{17}$

equating corresponding value

we get

adjacent=10

hypotenuse=17

perpendicular=x

now

by using Pythagoras law

Hypotenuse ²=perpendicular²+adjacent ²

substituting value

17²=x²+10²

17²-10²=x²

x²=17²-10²

x²=189

doing square root

$\sqrt{x²}=\sqrt{189}$

x= $3\sqrt{21}$

now

In I Quadrant sin angle is positive

Sin $\theta_{1}=\frac{perpendicular}{hypotenuse}$

<h3>Sin $\theta_{1}=\frac{3\sqrt{21}}{17}$ </h3>

I think when you divide decimals the numbers get bigger but when you divide by a whole number, they get smaller.

Which of the five measures of center (the mean, the median, the trimmed mean, the weighted mean, and the mode) can be calculated

Sever21 [200]

Quantitative data is information that can be measured, while qualitative data is descriptive data which can not be measured.
All five measures (the mean, the median, the trimmed mean, the weighted mean and the mode) can be calculated for quantitative data only, because they all use values in order to be calculated.
