((13+-17)/2, (-24+-6)/2)
((-4)/2, (-30)/2)
(-2,-15,)

Which statement best describes the association between variable X and variable Y?
Maksim231197 [3]

Answer:

Perfect positive association

Step-by-step explanation:

Definition: A perfect positive association means that a relationship appears to exist between two variables, and that relationship is positive 100% of the time. Two variables have a positive association when the values of one variable tend to increase as the values of the other variable increase. (+1 indicates a perfect positive linear relationship)

Definition: A perfect negative association means that a relationship appears to exist between two variables, and that relationship is negative 100% of the time. Two variables have negative association when the values of one variable tend to decrease as the values of the other variable increase. (-1 indicates a perfect negative linear relationship)

Values between 0.3 and 0.7 (-0.3 and -0.7) indicate a moderate positive (negative) linear relationship.

From the graph we can see that this relationship shows perfect positive association (both variables increase and we can plot the straight line which will include all points)

When h has the value 12 calculate 5h -2
OLga [1]
The answer to this question is 58. This works because 5h = 5 * h and since h = 12 then that equals 60 and then you minus 2 from 60 and your answer is 58.
