Let
be the root with the positive square root and
the root with the negative square root. Then
The simplest quadratic with these roots can be written as
The correlation coefficient (r) is a number that describes how closely the numbers in the data set are related. The correlation coefficient will always be between −1.0 and +1.0. If the correlation is positive, there is a positive relationship. If it is negative, the relationship is negative. If the two are not correlated at all, the correlation coefficient will be 0. Strong and weak correlations are a little more subjective in that there is no exact cutoff between strong and weak, but generally, any r value that is close to either 1 or negative 1 is considered strong. Any value of r that is closer to 0 is considered weak.
Answer:
Step-by-step explanation:
2r+4<8
subtract 4 from both sides
2r<4
divide by two
no need to reverse the sign since you are not dividing by a negative number
r<2
The answer is 1,163, my friend!
