When a pair of variables have a positive correlation will the slope in the regression equation always be positive?
Yes
Can variables be positive or negative?
both, variables can be anything
What is a positive slope for an equation?
the positive slope for an equation is a shdjcdhksfdgkf
How do you solve equations with power variables?
To solve equations with power variables, first isolate the term with the variable raised to a power. If it's in the form (x^n = a), take the (n)-th root of both sides to solve for (x), remembering to consider both positive and negative roots if (n) is even. For more complex equations, you may need to rearrange the equation or use logarithms for variables in the exponent. Always check your solutions by substituting them back into the original equation.
If the discriminant of an equation is positive is true of the equation?
If the discriminant of a quadratic equation is positive, it indicates that the equation has two distinct real roots. This means that the graph of the equation intersects the x-axis at two points. A positive discriminant also suggests that the solutions are not repeated and that the parabola opens either upward or downward, depending on the leading coefficient.

Yes
How many solutions do absolute value equations have?
An equation with absolute values instead of simple variables has twice as many solutions as an otherwise identical equation with simple variables, because every absolute value has both a negative and a positive counterpart.
Can variables be positive or negative?

What is the equation of 7 to the negative 2 power as a positive?
7-2 IS positive. You do not need an equation for it. And if it were not positive, no correct equation would show it to be positive.
The equation y -3x2 describes a parabola. Which way does the parabola open?
The given terms can't be an equation without an equality sign but a negative parabola opens down wards whereas a positive parabola opens up wards.
What is positive Correlation?
Positive correlation is a relationship between two variables in which both variables move in tandem that is in the same direction.
What does it mean when two variables have a positive correlation?
A positive correlation between two variables means that there is a direct correlation between the variables. As one variable increases, the other variable will also increase.
In the equation X is x positive negative or zero?
There is no equation in the question and so there can be no answer.
What are the positive and negative effects of democracy?
freedom of speech and equality is spread.
If the discriminant of an equation is positive is true of the equation?
If the discriminant of a quadratic equation is positive, it indicates that the equation has two distinct real roots. This means that the graph of the equation intersects the x-axis at two points. A positive discriminant also suggests that the solutions are not repeated and that the parabola opens either upward or downward, depending on the leading coefficient.
What does a correlation coefficient of 0.8 mean?
It means that there is a strong positive association between changes in the two variables being studied. Positive association means that the two variables tend to increase together or decrease together. Note that there is no mention of a causal relationship between the variables.
