You didn't give the fourth zero, but the answer is still false. If you have a root or an imaginary number as a zero, then its conjugate is also a zero. So if 8i is a zero, then -8i must also be a zero, and if 4i is a zero, then -4i must be a zero, with those zeros and -4, the number of zeroes exceeds the number of zeroes that a fourth degree polynomial can have.

Which of these r-value represents the weakest correlation?
Tanya [424]

Answer:

Option C is correct.

The value of r=0.2 represents  the weakest correlation.

Step-by-step explanation:

Strongest correlation states that a linear relationship is indicated by a correlation coefficient of -1 or 1.

Weakest correlation states that a linear relationship is indicated by a correlation coefficient equal to 0 or if the value is nearest to 0, then it also represents the weakest correlation.

From the options, the only r-value that is very close to 0 is 0.2.

Therefore, the r-value represents the weakest correlation is, 0.2
