FAQ Math 47

What is Causation in Math?

Causation in math refers to a relationship where one event or variable directly causes another event or variable to occur. It is stronger than correlation because it shows a cause-and-effect relationship.

What is Circle in Math?

A circle is a 2D shape consisting of all points in a plane that are a fixed distance (radius) from a central point (center). The equation of a circle in a coordinate plane is $(x – h)^2 + (y – k)^2 = r^2$, where $(h, k)$ is the center and $r$ is the radius.

What is Co-Prime Number in Maths?

Two numbers are said to be co-prime (or relatively prime) if their greatest common divisor (GCD) is 1. For example, 8 and 15 are co-prime because they have no common factors other than 1.

What is Commerce Without Maths?

Commerce without maths refers to studying subjects related to business, economics, and trade without taking mathematics as a subject. Some curricula offer this option for students not pursuing math-intensive career paths.

What is Congruent in Math?

In geometry, congruent means that two shapes or figures have the same size and shape. For example, two triangles are congruent if their corresponding sides and angles are equal.

What is Consecutive in Math?

Consecutive numbers are numbers that follow each other in order without gaps. For example, 4, 5, 6 are consecutive numbers. This term can apply to integers, even numbers, odd numbers, etc.

What is Consistent in Math?

A system of equations is called consistent if it has at least one solution. If no solution exists, the system is called inconsistent.

What is Construction in Maths?

In geometry, construction refers to the process of drawing shapes, angles, and lines accurately using a compass and a straightedge, without measuring.

What is Correlation in Math?

Correlation is a statistical measure that describes the strength and direction of a relationship between two variables. A positive correlation means both variables increase together, while a negative correlation means one increases as the other decreases.

What is Counting On in Math?

Counting on is a strategy used in addition where you start with the larger number and count up by the smaller number. For example, to solve $7 + 3$ , start with 7 and count three more (8, 9, 10).

What is Cubed in Math?

A number is said to be cubed when it is raised to the power of 3. For example, $2^3 = 2 \times 2 \times 2 = 8$ . This represents the volume of a cube with sides of that number’s length.

What is Cylinder in Maths?

A cylinder is a 3D shape with two parallel circular bases connected by a curved surface. The volume of a cylinder is given by $V = \pi r^2 h$ , where $r$ is the radius of the base and $h$ is the height.

What is Data Handling in Maths?

Data handling involves collecting, organizing, and interpreting data to gain insights and make informed decisions. It includes using tables, graphs, and charts to represent data.

What is Data Handling in Maths Class 7?

In Class 7, data handling includes topics like collecting data, organizing it into tables, constructing bar graphs and pie charts, and calculating measures like mean, median, and mode.

What is Data Handling in Maths Class 8?

For Class 8, data handling continues with more advanced topics, such as probability, histogram construction, and interpreting different types of graphs and measures of central tendency.

What is Data Handling in Maths for Class 5?

In Class 5, data handling covers the basics of gathering and organizing data into tables and simple bar graphs. Students learn to interpret basic data representations and solve related problems.

What is Decreased in Math?

To decrease in math means to make a value smaller. For example, if a number is decreased by 5, you subtract 5 from it.

What is Diameter in Math?

The diameter of a circle is the longest distance across the circle, passing through the center. It is twice the radius. The formula for diameter is $d = 2r$ .

What is Direct Variation in Math?

In direct variation, two variables are proportional to each other. When one variable increases, the other increases at a constant rate. The relationship can be expressed as $y = kx$ , where $k$ is the constant of proportionality.

What is Displacement in Math?

In mathematics, displacement refers to the change in position of an object. It is a vector quantity, having both magnitude and direction.

What is Distributive Property in Math?

The distributive property states that multiplying a sum by a number is the same as multiplying each addend individually by the number and then adding the products. For example, $a(b + c) = ab + ac$ .

What is dm in Maths?

In maths, dm stands for decimeter, a unit of length equal to one-tenth of a meter (0.1 meters).

What is e Used for in Math?

The constant e (approximately 2.718) is the base of natural logarithms. It appears frequently in calculus, particularly in growth and decay models and in the exponential function $e^x$ .

What is Enlargement in Maths?

Enlargement is a transformation that increases or decreases the size of a figure, while maintaining its shape. The scale factor determines the degree of enlargement.

What is Eureka Math?

Eureka Math is a comprehensive curriculum that emphasizes a deep understanding of mathematical concepts. It encourages students to learn math by building on prior knowledge and applying problem-solving skills.

What is Exceeds in Math?

In math, exceeds means “is greater than.” For example, if $x$ exceeds 7, this means $x > 7$ .

What is Exponential Growth in Math?

Exponential growth occurs when a quantity increases at a rate proportional to its current value. The general form is $y = a \cdot e^{kt}$ , where $a$ is the initial value and $k$ is the growth rate.

What is Factorial in Math?

The factorial of a number $n$ , written as $n!$ , is the product of all positive integers less than or equal to $n$ . For example, $4! = 4 \times 3 \times 2 \times 1 = 24$ .

What is Fewer in Math?

Fewer means a smaller number. For example, if you have fewer than 5 apples, you have less than 5 apples.

What is Figure in Maths?

A figure in math refers to a shape, such as a triangle, square, or circle, or a drawing that represents a mathematical concept.
