MATH
Mathematics (Math) is a vast subject that encompasses many different subcategories. Some common subcategories of Mathematics MCQs (Multiple Choice Questions) include:
- Algebra: This subcategory covers questions related to algebraic equations, operations, and functions, including topics such as polynomials, matrices, and linear algebra.
- Geometry: This subcategory covers questions related to the study of shapes and their properties, including topics such as lines, angles, triangles, and circles.
- Trigonometry: This subcategory covers questions related to the study of triangles and their properties, including topics such as trigonometric functions, identities, and equations.
- Calculus: This subcategory covers questions related to the study of rates of change and accumulation. Including topics such as differentiation, integration, and limits.
- Statistics: This subcategory covers questions related to the collection, analysis, and interpretation of data. Including topics such as probability, distributions, and hypothesis testing.
- Applied Mathematics: This subcategory covers questions related to the application of mathematical concepts. And techniques to solve practical problems in various fields, including topics such as optimization, game theory, and cryptography.
These categories of math can be useful for students and professionals to organize and classify different types of Mathematics MCQs. And to focus their study efforts on specific areas of mathematics that are relevant to their interests and career goals.
a number exceeds another number by 5.the sum of the numbers is 19. find the smaller number ?
Answer Detail
a number exceeds another number by 5. the sum of the numbers is 19. find the smaller number? Let one of the numbers be βxβ; then the other is βx+5β. Equation: x + x+5 = 19 2x = 14 x = 7 (the 1st number) x+5 = 12 (the other number)
The mean of five numbers is 18. If one number is excluded, then their mean is 16, the excluded number is______?
Answer Detail
The correct option is B) Mean of 5 numbers =18 β Sum of these 5 numbers =18Γ5=90 Let the number that has been excluded be x New mean = 4 90βx β =16 Solving this, we get 90βx=64 β΄x=26
