The equation x^2+ (k - 3)x + (3 - 2k) = 0, where k is a constant, has two distinct real roots.
Lisa [10]

Step-by-step explanation:

For quadratic equation ax^2 + bx + c = 0 to have two distinct real roots,

b^2 - 4ac must be positive.

b^2 - 4ac > 0

(k - 3)^2 - 4(3 - 2k) > 0

k^2 - 6k + 9 - 12 + 8k > 0

k^2 + 2k - 3 > 0

Which of the following correlation coefficients represents the strongest relationship between two factors? A. –.15 B. –.80 C. +.
Lena [83]

Answer:

The strongest relation between the two factors is B.) -0.8

Step-by-step explanation:

The correlation coefficient typically varies from -1 to 1.

The value of -1 for the correlation coefficient denotes that the two variables are have a very strong negative  correlation.

The value of +1 for the correlation coefficient denotes that the two variables are have a very strong negative  correlation.

Therefore among the four options given of -0.15, -0.8, 0.38, 0.03 the strongest relation between two factors is given by -0.8 but as the '-' sign indicates the two factors are negatively correlated.

Negative correlation means that if one variable is high the other would be low.

Positive correlation means that if one variable is high then the other variable is also high and if one variable is low then the other is also low.
