Which of the following is a description of the data with a correlation coefficient of -0.2?
2 answers:
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:
Step-by-step explanation:
Ok, so first substitute x for 4 in
"g(x) = 5x + 1", and x for 3 in
"k(x) = 2/x + 2x". Now you got:
g(4) = 5(4) + 1
k(3) = 2/(3) + 2(3)
Now you can solve each individually.
g(4) = 5 × 4 = 20
20 + 1 = 21
g(4) = 21
k(3) = 2 × 3 = 6
6 + 2/3 = 6 2/3
k(3) = 6 2/3
g(4) + k(3) = 21 + 6 2/3 = <u>27 2/3</u>
Hope this helps :)
