The r-value that represents the strongest correlation is (a) - 0.83
The correlation coefficient has its value to be from -1 to 1
The closer the value to 1 or -1, the stronger the correlation
-0.83 is closer to -1 than the other values closer to 1 or -1
Hence, the r-value that represents the strongest correlation is (a) - 0.83

Answer:
–0.83
Step-by-step explanation:
In regression analysis, the coefficient of correlation is a statistic which indicates an association between the independent variables and the dependent variable. The coefficient of correlation is represented by "r" and it has a range of -1 to 1. The nearer the r-value to -1 or 1 the better the correlation.
b.(–4 + i) + 4i = 4i + (–4i + i)
c.4i × (–4i + i) = (4i – 4i) + (4i × i)
d.(–4i + i) + 0 = (–4i + i)
The associative property states that we can regroup the terms of an expression and obtain the same result.
We have then:
The expression that complies with this property is given by:
Answer:
An equation that shows an example of the associative property of addition is:
a. (- 4 + i) + 4i = -4 + (i + 4i)
The correct option is i.e., .
Further explanation:
Concept used:
The associative property of the addition states that the addition of numbers cannot affect by the grouping of the number.
Here, in the above equation the value of is always equal to the value of whether the grouping of number is changes or not.
Calculation:
Now check the option to get the answer.
First check option (a)
In the above equation the grouping of the number is changed.
Now check the values of left hand side and right hand side.
The value of LHS is same as RHS.
Therefore, option (a) is correct.
Now check option (b)
The term should be associated with but it is associated with .
Therefore the option (b) is incorrect.
Now check option (c)
The above expression does not follow any property.
Therefore the option (c) is incorrect.
Now check option (d)
The above expression follows additive property not associative property.
Therefore the option (d) is incorrect.
Thus, the correct option is i.e., .
