a researcher is conducting a study and you are hired to them analyze their data. they have already looked at scatterplots and they give you only the linear correlation coefficient to consider.

suppose that the correlation r between two quantitative variables was found to be r = 0.12 based on this information, what would you advise?

-there is a weak linear relationship between the two variables.

-there is no relationship between the two variables.

-there is a strong linear relationship between the two variables.

-there is a strong relationship between the two variables.

-none of the above.

do you have the measurements?

the answer is 8.64

step-by-step explanation:

$15.40 per mile

step-by-step explanation:

you have to round up to 4 because 6 is over 5 so you have to round the 3 up to 4

1. when "a" is a root of a polynomial, (x -a) is a factor of it. for the three roots given, the factors of the desired polynomial are (x +2)(x -1/2)(x -3).

in order to make the leading coefficient be negative, we need to multiply this product by a negative number. any negative number will do, but we choose a small (magnitude) value that will eliminate the fraction: -2.

then

f(x) = -2(x +2)(x -1/2)(x -3) = -(x +2)(2x -1)(x -3)

= -(2x² +3x -2)(x -3)

= -(2x³ -3x² -11x +6)

f(x) = -2x³ +3x² +11x -6

2. a graph created by the desmos on-line graphing calculator is shown, and the zeros are highlighted.

3. as indicated in part 1, the multiplier of this equation can be anything and the zeros will remain the same. you want a negative leading coefficient, so the "anything" is restricted to any of the infinite number of numbers that will make that be the case.
