Determine the type of correlation that exists in the given data set. r s –40 2 –30 36 –20 27 –10 78 0 13 10 96 20 39 30 4 40 68 a. a positive correlation exists between variables r and s. b. a negative correlation exists between variables r and s. c. no correlation exists between variables r and s. d. there is not enough information to determine what type of correlation exists between variables r and s.

the answer is actually C

Step-by-step explanation: I took the test and the answer is C: no correlation exists between variables R and S

1.true 2.false? ? i think. .

step-by-step explanation:

3. (5x + 1) - (-10x + 6)

simplify the answer choice. combine like terms. remember to distribute the negative to the terms inside the second parenthesis. also remember that two negatives = one positive, and one of each sign = negative.

- (-10x + 6) = + 10x - 6

simplify. combine like terms:

5x + 1 + 10x - 6

5x + 10x + 1 - 6

15x - 5

∴ it is your answer
