NO LINKS Use the correlation coefficient to find the coefficient of determination.

What percent of variation in the response variable can be explained by changes in the explanatory variable?

r=−0.5

coefficient of determination: 0.25; 25% of the variation in the response variable can be explained by changes in the explanatory variable

coefficient of determination: 0.1; 10% of the variation in the response variable can be explained by changes in the explanatory variable

coefficient of determination: 0.5; 50% of the variation in the response variable can be explained by changes in the explanatory variable

coefficient of determination: 0.71; 71% of the variation in the response variable can be explained by changes in the explanatory variable

4.6875 pounds

step-by-step explanation:

(x3 + 6x2 + 2x - 6) • (x - 1)

step-by-step explanation:

polynomial long division :

3.2     polynomial long division

dividing :   x4+5x3-4x2-8x+6

                              ("dividend")

by         :     x-1     ("divisor")

dividend     x4   +   5x3   -   4x2   -   8x   +   6

- divisor   * x3     x4   -   x3            

remainder         6x3   -   4x2   -   8x   +   6

- divisor   * 6x2         6x3   -   6x2        

remainder             2x2   -   8x   +   6

- divisor   * 2x1             2x2   -   2x    

remainder               -   6x   +   6

- divisor   * -6x0               -   6x   +   6

remainder                     0

quotient :   x3+6x2+2x-6   remainder:   0

the answer is b.)

< 1=< 2

c.

step-by-step explanation:

because first you have to add the 4x, 9x, and the 7x together and you get 20x and then you add the last numbers up and you get 5and then you put the subtraction sign in there and that's how you get the answer.
