What is the average of the two roots of quadratic equation?
In a quadratic y = ax² + bx + c, the roots are where y = 0, and the parabola crosses the x-axis. The average of these two roots is the x coordinate of the vertex of the parabola.
How is the x-value of the vertex of a parabola related to the zeros of the function?
For a parabola in a normal position ... with its nose either straight up or straight down ... the x-value of the vertex is midway between the zeros of the function, i.e. their average.
Is the average of a set of negative numbers is a positive?
The average of any group of numbers is always more than the smallest one and less than the largest one. If the numbers are all negative, then their average is negative too.
Is there negative correlation between weight and distance walked on an average day?
That's a question that can only really be answered via a study. Take a random sample of people (from your school for example) and plot their weight against their average daily walking distance (you may have to make your subjects carry a pedometer during the study period). Do you see a negative relationship on the graph?As a second step, calculate the correlation coefficient. As negative correlation gets stronger the correlation coefficient will get closer to -1.
Can the average be zero?
Sure. If some of the items on the list are positive and some are negative, then their average can be positive, negative, or zero. But if all of them are positive, then their average must be more than zero. Remember that the average is always greater than the least item on the list, and less than the greatest one.

What is the sum of the average and four is negative 6?
It is a mathematical statement. It means that the average of a set of numbers is negative 10 and the sum of this average and four is, therefore, negative six!
What is the average negative twelve negative fourteen negative three and positive five?
Negative six is.
Can average deviation be negative?
No, average deviation cannot be negative. Deviation is a representation of differences between numbers. A difference is always an absolute value, so the number cannot be negative (even though subtracting the deviation from an average may result in a a negative result).
Is the average of a set of negative numbers is a positive?
The average of any group of numbers is always more than the smallest one and less than the largest one. If the numbers are all negative, then their average is negative too.
What conditions will the average be a negative number?
The sum of the set of values must be negative.
Is the average of a set of negative numbers positive or negative?
It would be negative because there would be more negatives that positives
What is a negative mean?
IN statistics yes there is a negative mean. Mean is the average of multiple numbers. Negative is opposite of positive.
