6 Questions
What is the definition of a rational number?
A rational number is a number that can be expressed as p/q, where p and q are integers and q ≠ 0.
What is the difference between a linear equation and a quadratic equation?
A linear equation has a degree of 1, whereas a quadratic equation has a degree of 2.
What is the purpose of factorization in algebra?
To express an algebraic expression as a product of simpler expressions.
What is the coordinate geometry used for?
To study geometric shapes using coordinates (x, y) on a graph.
What is the formula for the circumference of a circle?
The formula for the circumference of a circle is 2πr, where r is the radius.
What is the definition of mean in statistics?
The mean is a measure of central tendency, calculated by adding all the values and dividing by the number of values.
