Inequalities is a topic in ....
Correct Answer
A. Maths
Explanation
Inequalities is a topic in maths. It involves comparing two values or expressions using symbols such as <, >, ≤, or ≥ to indicate the relationship between them. Inequalities are used to represent situations where one quantity is greater than or less than another, and they are commonly used in algebraic equations and problem-solving. Understanding inequalities is important in various mathematical concepts and applications, such as graphing linear inequalities, solving systems of inequalities, and analyzing inequalities in real-world scenarios.
2.
In mathematics, an inequality is a relation that holds between .... values when they are different.
Correct Answer
B. Two
Explanation
An inequality is a mathematical relation that holds between two values when they are different. It compares the values and determines whether one is greater than, less than, or not equal to the other. This is why the correct answer is "two" as it accurately describes the nature of an inequality.
3.
In contrast to strict inequalities, there are how many types of inequality relations that are not strict?
Correct Answer
A. Two
Explanation
There are two types of inequality relations that are not strict. This means that there are two ways in which numbers can be related to each other in a non-strict manner. The concept of non-strict inequalities encompasses scenarios where numbers can be equal or differ without imposing a strict "greater than" or "less than" requirement. It introduces a broader spectrum of relationships between numerical values, providing flexibility in mathematical comparisons.
4.
Mathematics is taught in .....
Correct Answer
B. School
Explanation
Mathematics is taught in schools because it is considered an essential subject for developing logical thinking, problem-solving skills, and numeracy. Schools provide a structured environment where students can learn mathematical concepts, formulas, and techniques through textbooks, lectures, and practical exercises. Additionally, schools offer qualified teachers who can guide and support students in their mathematical journey. The curriculum in schools is designed to progressively build upon mathematical knowledge and skills, ensuring a comprehensive understanding of the subject. Overall, schools serve as the primary institution for teaching mathematics due to their educational infrastructure and expertise in delivering academic content.
5.
Who is not a scientist here?
Correct Answer
A. Will Smith
Explanation
Will Smith is not a scientist because he is primarily known as an actor and musician, not for any scientific contributions or research. On the other hand, Albert Einstein, Isaac Newton, and Bill Nye are all well-known scientists who have made significant contributions in their respective fields. Therefore, Will Smith is the only one in the list who is not a scientist.
6.
This symbol "<" represents ...
Correct Answer
B. Less than
Explanation
The symbol "<" represents "less than" in mathematics. It is used to compare two numbers or quantities, indicating that the value on the left side is smaller or inferior to the value on the right side. This symbol is commonly used in mathematical equations, programming languages, and inequalities to express the relationship between two values.
7.
The symbol ">" represents ....
Correct Answer
A. Greater than
Explanation
The symbol ">" represents "greater than" in mathematical and logical contexts. It is used to compare two values, indicating that the value on the left side is larger than the value on the right side.
8.
The symbol "≤" could represent ....
Correct Answer
C. Equal to
Explanation
The symbol "≤" represents "less than or equal to." It is used to compare two values, indicating that the left value is either less than or equal to the right value. It does not represent "greater than" or "none." Therefore, the correct answer is "equal to."
9.
The notation "≠" means what?
Correct Answer
A. Not equal to
Explanation
The notation "≠" is used to represent "not equal to". It indicates that two values or expressions are not equal to each other.
10.
Inequalities is studied under ....
Correct Answer
A. Maths
Explanation
Inequalities is a topic studied under maths. It involves comparing two values or expressions using inequality symbols such as greater than, less than, greater than or equal to, and less than or equal to. By studying inequalities, mathematicians can analyze and solve problems related to equations, systems of equations, and real-life situations involving variables and constraints. Understanding inequalities is crucial in various fields such as economics, physics, and engineering, where mathematical modeling and optimization are required.
