What is the Pythagorean Theorem?

Back

The Pythagorean Theorem states that in a right triangle, the square of the length of the hypotenuse (c) is equal to the sum of the squares of the lengths of the other two sides (a and b). Formula: a² + b² = c².

Front

Define a linear equation.

Back

A linear equation is an equation that makes a straight line when graphed. It can be written in the form y = mx + b, where m is the slope and b is the y-intercept.

Front

What is the slope of a line?

Back

The slope of a line is a measure of its steepness, calculated as the rise over run (change in y over change in x). It is often represented by the letter m.

Front

Explain the concept of a function.

Back

A function is a relation between a set of inputs and a set of possible outputs where each input is related to exactly one output. It can be represented as f(x).

Front

What is the difference between mean, median, and mode?

Back

Mean is the average of a set of numbers, median is the middle value when numbers are arranged in order, and mode is the number that appears most frequently.

Front

What is the area of a rectangle?

Back

The area of a rectangle is calculated by multiplying its length (l) by its width (w). Formula: Area = l × w.

Front

Define the term 'probability'.

Back

Probability is a measure of the likelihood that an event will occur, expressed as a number between 0 (impossible) and 1 (certain).

Front

What is a quadratic equation?

Back

A quadratic equation is a second-degree polynomial equation in the form ax² + bx + c = 0, where a, b, and c are constants and a ≠ 0.

Front

Explain what a variable is in mathematics.

Back

A variable is a symbol, often a letter, that represents a number in mathematical expressions or equations. For example, x and y are common variables.

What is the formula for the circumference of a circle?

Back

The circumference of a circle is calculated using the formula C = 2πr, where r is the radius of the circle.
