Answer:
64%
Step-by-step explanation:
The percentage of variation in the dependent variable explained by the estimated regression is calculated with the coefficient of correlation as follows:
First, square the coefficient of correlation: 0.8^2 = 0.64
And then, multiply this result by 100, so that, it is expressed as a percentage: 0.64*100 = 64%
Answer:
i thnk 10
Step-by-step explanation:sorry
6x^3+6x^5+12x^4=6x^3 (1+6X^2+2X)= 6X^3 [1+2X(3X+1)]
Answer:
6x^2 - 2
Step-by-step explanation:
plug in f(x) into the g(x) formula given
g(f(x)) = (3x)^2 + 1
simplify
= 9x^2+2
plug in g(x) into the f(x) formula given
f(g(x)) = 3(x^2+1)
distribute
= 3x^2 +3
set g(f(x)) - f(g(x))
(9x^2+2) - (3x^2+3)
carry the negative
9x^2+2-3x^2-3
simplify by combining like terms
6x^2-2
I haven’t done this in a while, but I believe that the “of” in the equation means multiply so you do 3/4 x 1/3 to get 3/12 (simplified to 1/4)!!
