3) It is an array of numbers or unknowns, arranged in rows and columns, presented in brackets
4) Programming

6. 1) The data are all presented in tables and are very organized.
2) It is arranged in a manner where people can process and compare the information easily without confusion.
3) Matrix is the rectangular array of numbers, symbols, or expressions, arranged in rows and columns.
4) It is used for the encryption of codes and was used to analyze airplane vibrations during World War II.

7. 1) All of the data is presented in table except the sample E it conveys its message through pictures.
2) It is very organized and the audience need not to take effort to find the information but can easily spot the information she wants.
3) A matrix (plural matrices) is a rectangular array of numbers, symbols, or expressions, arranged in rows and columns.
4) It can be used for game theories.

8. 1) Are quite organized and they are comparing a number of at least 2 things.
2) Since the information that they are presenting are in an organized manner, people viewing it will find it very easy to find what they are looking for.
3) Mathematics: It's a rectangular array of quantities/expressions in rows and columns.
4) They can be used to represent Finite and Direct graphs(Real world data)

9. 1) The data presented are arranged in a neat position making it easier for people to read.
2) People won't have much problem reading and finding the information they need as it is very neat and organized.
3) A matrix is a collection of numbers arranged into a fixed number of rows and columns. Usually the numbers are real numbers.
4) It can be used for data presentation.

10. 1) The data is presented as a table.
2) The data is easy to understand due to the format used for presentation
3) Data presented in rows and columns
4) It is used in Science to present results/data collected

11. 1) The information is presented in a table- like manner, with columns of data.
2) Since it is so organized, the data that is wanted can be easily found. The information is such that everything relevant can be found in a single row, and is hence easy to use and reference.
3) Matrices is data being presented in rows and columns based on their relevance.
