Question

Which of the following sets of data would you likely represent with a square matrix? Check all that apply.

Answer 1

Answer : B and C

Explanation :

firstly, we should know the definition of square matrix. It is a matrix in which number of rows is equal to number of columns

In case of A : it is given that several number of airlines  and several number of columns

if we consider the case of more number of airlines say 5 and we have only 4 cities that these 5 airlines offer services to. Then it will not  form a square matrix

NOTE: it would have formed the square matrix if there would have been equal number of airlines and  cities.

In case of  B: in this case we will have equal number of members in each team.

In case of C : in this case we are given with equal number of  equations and unknowns

In case of D: in this case we have augmented matrix which is formed by appending the column of the matrices given so it can never form a square matrix.
