Find the point P along the directed line segment from point A(-8,-3) to point B(6,12) that divides the segment in the ratio 1 to

Angelina_Jolie [31]

Bearing in mind that, the ratio here is 1:7 form A to B, that matters, because, the AB segment gets split in 8 pieces, and AP takes 1 slice whilst PB takes 7 slices

$\bf \left. \qquad \right.\textit{internal division of a line segment}
\\\\\\
A(-8,-3)\qquad B(6,12)\qquad
ratio1=1\qquad ratio2=7\qquad 1:7
\\\\\\
\cfrac{AP}{PB} = \cfrac{1}{7}\implies \cfrac{A}{B} = \cfrac{1}{7}\implies 7\cdot A=1\cdot B
\\\\\\
7(-8,-3)=1(6,12)\\\\
-------------------------------\\\\$

$\bf { P=\left(\cfrac{\textit{sum of "x" values}}{ratio1+ratio2}\quad ,\quad \cfrac{\textit{sum of "y" values}}{ratio1+ratio2}\right)}\\\\
-------------------------------\\\\
P=\left(\cfrac{(7\cdot -8)+(1\cdot 6)}{1+7}\quad ,\quad \cfrac{(7\cdot -3)+(1\cdot 12)}{1+7}\right)$

Please help me answer this ASAP! The two-way table shows the number of ninth and tenth graders who prefer going to sporting even

Elis [28]

<h2>Answer</h2>

0.43

<h2>Explanation</h2>

Remember that $RelativeFrecuency=\frac{Frecuency}{SumOfAllFrecuencies}$

Since the problem is telling us "Among tenth graders", we must focus on the 10th graders row only. From the row, we can infer that the frequency is the number of 10th graders who prefer going to sporting events, so $Frecuency=6$ . Now, the sum of all frequencies will be the sum of all the 10th graders, so $SumOfAllFrecuencies=6+8=14$ . Let's replace the values:
