Which of the following data sets indicates a strong negative correlation? {(-3, 8), (-2, -6), (-1, 4), (0, -2)} {(-2, -4), (0, -2), (2, 0), (4, 2)} {(-2, 4), (-1, 2), (0, 0), (1, -2)

{ (-2,4) , (-1,2) , (0,0) , (1,-2) } data set indicates a strong negative correlation.

Step-by-step explanation:

Given Set of points are the following;

Set 1 - { (-3,8) , (-2,-6) , (-1,4) , (0,-2) }   , Set 2 - { (-2,-4) , (0,-2) , (2,0) , (4,2) }  and Set 3 - { (-2,4) , (-1,2) , (0,0) , (1,-2) }

Strong Negative Correlation occurs when value of one variable increase then value of second variable decreases.

Strong Positive Correlation occurs when value of one variable increase then value of second variable Also increases.

This can be check by marking them on graph paper.

Graph paper is attached.

From graph paper and definition Data Set 3  indicates a strong negative correlation.

Therefore,  { (-2,4) , (-1,2) , (0,0) , (1,-2) } data set indicates a strong negative correlation.

256π units²   (answer b)

step-by-step explanation:

the formula for the surface area of a sphere of radius r

is             a = 4πr²

and so, if r = 8 units, then the surface area is:

a = 4π(8 units)² = 256π units²   (answer b)

i think it is everything has to equal 180 so, if i correct 4=c. 6=d. 8=a. 7=b. and the last question would be c. because they are parallel lines and they are congruent.

step-by-step explanation:

the reason everything has to equal to 180 is because that is how it works. i'm guessing that is its rule. 4 and 8 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 6 and 7 are congruent and parallel so, that would be 30+30 because they have the same number. it would equal 60. 60+60 is 180. so, now you have your answer
