The line of best fit is a line on a scatter plot graph with equal number of points on either side of it, it is the equivalent of average.
the line of best fit on your graph predicts the average score of a student who studies for 2 hours is 16
{a+c=529
{1.75c+2.25a=1118.75
{9a+9c=4761
-
{7c+9a=4475
2c=286
c=143
a=529-143=386
There are 143 children and 386 adults used the public swimming pool.
They are equal because if you make 4/5 into a denominator of 10 it is 8/10
<span>By similarity of triangles we have the following relationship:</span><span> </span><span> (y) / (12) = (37.5) / (20)</span><span> </span><span> Rewriting we have:</span>
<span> (y) = ((37.5) / (20)) * (12)</span>
<span> Simplifying we have:</span>
<span> y = (1,875) * (12)</span>
<span> Then, the value of y is:
