Step-by-step explanation:
2x+1x= -2+1
3x= -1
3x÷3= -1÷3
x=|-3.3333..|=3.33333.. or
The equation for the horizontal line that passes through (1.5, 2.5) is y = 2.52 * Y = 2.5 :: Y = 1.5 " y = 1.52

0.64 or 64% of the variance for the y scores is predicted by its relationship with x.
<h3>What is coefficient of determination?</h3>The percentage of the variation in the dependent variable that can be predicted from the independent variable is known as the coefficient of determination, abbreviated R2 or r2, in statistics.
<h3>How to find the variance for the y scores?</h3>given that
A set of n = 25 pairs of scores (x and y values) has a pearson correlation of r = 0.80.
now we have to find the variance for the y scores.
here, r=0.80 then
which means 0.64 or 64% of the variance for the y scores is predicted by its relationship with x.
