Use the given information to find the coefficient of determination. a regression equation is obtained for a collection of paired data. it is found that the total variation is 20.711, the explained variation is 18.592, and the unexplained variation is 2.119.

a) 1.114.
b) 0.102.
c) ) 0.898.
d) 0.114.

Option c) 0.898

Step-by-step explanation:

Given :

Total variation = 20.711

Explained variation = 18.592

unexplained variation = 2.119

we know that coefficient of determination  r² =

                                                                       =

                                                                       = 0.897687 ≈ 0.898

Option c, 0.898 is the answer.

answer: solve 5\cdot 2^x=2405⋅2  

x

=2405, dot, 2, start superscript, x, end superscript, equals, 240.

solution

to solve for xxx, we must first isolate the exponential part. to do this, divide both sides by 555 as shown below. we do not multiply the 555 and the 222 as this goes against the order of operations!

\begin{aligned} 5\cdot 2^x& =240 2^x& =48 \\ \end{aligned}  

5⋅2
