Answer:

a) = 0.9739

b) = 0.969

c) option A is correct

Step-by-step explanation:

Given that:

sample size n = 30

SST = 1803

SSR = 1756

$R^2 = \dfrac{SSR}{SST} \\ \\ R ^2 = \dfrac{1756}{1803} \\ \\ \mathbf{R^2 =0.9739}$

The adjusted $R_a^2$ is computed as:

$R_a^2 = 1 - (\dfrac{n-1}{n-p})(1-R^2)$

where;

$p = k+1 \\ p= 4+1 = 5$

$R_a^2 = 1 - (\dfrac{30-1}{30-5})(1-0.9739)$

$R_a^2 = 1 - (\dfrac{29}{25})(0.0261)$

$R_a^2 = 1 - (1.16)(0.0261)$

$R_a^2 = 1 -0.030276$

$\mathbf{R_a^2 \simeq 0.969}$

Simplify 2a^2b^3 (4a^2 + 3ab^2 - ab) =?

stellarik [79]

The correct answer is D.D. 8a^4b^3 + 6a^3b^5 - 2a^3b^4

You can tell this by the lead term alone. When you mutliply the term outside to the lead term, D is the only one that has that term.

2a^2b^3*4a^2 = 8a^4b^3

D. 8a^4b^3 + 6a^3b^5 - 2a^3b^4
