Answer: Low negative correlation
Step-by-step explanation:
High correlation: The value of correlation coefficient lies between -1 to -0.5 or 0.5 to 1.
Medium correlation : The value of correlation coefficient lies between -0.5 to -0.3 or 0.3 to 0.5.
Low correlation : The value of correlation coefficient lies between -0.3 to -0.1 or 0.1 to 3.
The given correlation coefficient :
Clearly it is negative having minus sign.
Also it lies between -0.3 to -0.1
Hence, the data with a correlation coefficient of -0.2 has a low negative correlation.
Answer:
(a) and
Step-by-step explanation:
Required
Which of a to d has no solution
(a) and
We have:
Sole for m
Divide by 6
So, we have:
and
implies that: m = -6,-7,-8,-9.....
implies that m = -3,-2,-1,0.....
<em>Hence, there is no solution</em>
