What does the term "compound events" describe in mathematics?

• A) A set of lines that all intersect at the same point.

• B) The probability resulting from two or more simple events.

• C) The volume of a cone.

• D) A linear function of the form y = b, where b is a constant.

Answer explanation

Compound events in mathematics refer to the probability resulting from two or more simple events, making option B the correct choice.

What is the definition of "compound interest"?

• A) The process of building something.

• B) Curved inwards.

• C) Where interest is calculated on both the amount borrowed and any previous interest.

• D) A group of curves obtained when a plane intersects a double cone.

Answer explanation

Compound interest is where interest is calculated on both the amount borrowed and any previous interest, making it different from simple interest.

What does "computation" refer to?

• A) The probability of some event (A), given the occurrence of some other event (B).

• B) Finding an answer by using mathematics or logic.

• C) Angles that have the exact same measurement.

• D) A statement that follows logically from other facts.

Answer explanation

The term 'computation' refers to finding an answer by using mathematics or logic, which is option B.

What does "congruent" mean in mathematics?

• A) To solve problems that use numbers.

• B) The relative frequencies placed in the body of a two-way relative frequency table.

• C) Having exactly the same shape and size.

• D) The process of changes from one form to another.

Answer explanation

Congruent in mathematics means having exactly the same shape and size, making option C the correct choice.

What is a "conjugate" in the context of mathematics?

• A) A group of curves obtained when a plane intersects a double cone.

• B) Two binomials whose only difference is the sign of one term.

• C) The volume (V) of a cone.

• D) A linear function of the form y = b, where b is a constant.

Answer explanation

A 'conjugate' in mathematics refers to two binomials whose only difference is the sign of one term, making option B the correct choice.

What is the definition of "converse" in a mathematical statement?

• A) The process of building something.

• B) Switching the hypothesis and conclusion of a conditional statement.

• C) To approach a finite limit.

• D) A set of lines that all intersect at the same point.

Answer explanation

The definition of 'converse' in a mathematical statement is switching the hypothesis and conclusion of a conditional statement, making it the correct choice B.

What is the definition of a coordinate system according to the academic vocabulary words for mathematics?

• A set of points, lines, or any other geometrical shapes that lie on the same plane.

• A standard grid, composed of lines of latitude and longitude, used to determine the absolute location of any object, place, or feature on the earth's surface.

• The plane figure obtained by the intersection of a solid by a plane.

• A method for solving a linear system of equations using determinants.

Answer explanation

The correct definition of a coordinate system in academic vocabulary for mathematics is a standard grid composed of lines of latitude and longitude used to determine the absolute location of any object, place, or feature on the earth's surface.

What does the term "coplanar" refer to in mathematics?

• A pair of numbers used to determine the position of a point on a graph.

• A set of lines or curves used to define a coordinate system.

• A set of points, lines, or any other geometrical shapes that lie on the same plane.

• The plane containing the "x" axis and "y" axis.

Answer explanation

The term 'coplanar' in mathematics refers to a set of points, lines, or any other geometrical shapes that lie on the same plane, making them all coplanar.

Which of the following best defines "correlation" in the context of mathematics?

• The degree to which two variables are related.

• The plane containing the "x" axis and "y" axis.

• A standard grid, composed of lines of latitude and longitude.

• A set of lines or curves used to define a coordinate system.

Answer explanation

Correlation in mathematics refers to the degree to which two variables are related, making it the best definition among the options provided.

What is a "corresponding angle" in geometry?

• An angle formed by two lines that are cut by another line, where the angles in matching corners are called corresponding angles.

• The angle in a right triangle opposite the longest side.

• The angle formed by the intersection of two lines that are not in the same plane.

• The angle between a base and an adjacent side in a polygon.

Answer explanation

An angle formed by two lines that are cut by another line, where the angles in matching corners are called corresponding angles.
