Answer:
Second option:
Third option:
Fifth option:
Step-by-step explanation:
By definition, a perfect square trinomial can be obtained by squaring binomials.
Then:
Knowing this, to obtain a perfect square trinomial, the binomials that you multiply must be equals.
Therefore, the products result in a perfect square trinomial are:
The value of a = 2.17 and b = 1.95.
<h3>What is regression line?</h3>A regression line is a graphic representation of the regression equation expressing the hypothesized relationship between an outcome or dependent variable and one or more predictors or independent variables;
y=
Correlation:
r=0.964
R-squared:
r²=0.9292
Hence, value of a and b is 2.17 and 1.95.
