      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The explanation for the given correct answer is that transposing a matrix involves swapping the elements of each row with the corresponding elements in the same column. This means that the rows become columns and the columns become rows in the transposed matrix. Therefore, the statement "Transpose matriks dalah matriks yang diperoleh dari menukar setiap elemen baris dengan elemen kolom matriks" is true.

    Rate this question:

  • 6. 

     matriks disamping memiliki ordo 3x2

    • A.

      True

    • B.

      False

    Correct Answer
    B. False
    Explanation
    The given statement is false. The matrix mentioned has an order of 3x2, which means it has 3 rows and 2 columns.

    Rate this question:

  • 7. 

    Jika matriks A berordo m x q dan matriks B berordo q x n maka hasil kali matriks A x B berordo m x n adalah syarat dari perkalian matriks

    • A.

      True

    • B.

      False

    Correct Answer
    A. True
    Explanation
    The statement is true because in order to multiply two matrices, the number of columns in the first matrix must be equal to the number of rows in the second matrix. In this case, the matrix A has q columns and the matrix B has q rows, satisfying the condition for matrix multiplication. Therefore, the product of matrix A and matrix B will have dimensions m x n.

    Rate this question:

    A. True
    Explanation
    A singular matrix is a matrix that does not have an inverse. In other words, it is not possible to find another matrix that, when multiplied with the original matrix, gives the identity matrix. This means that the original matrix cannot be "undone" or reversed. Therefore, the correct answer is true.

    The answer is true because matrix multiplication can be either correct or incorrect depending on the dimensions of the matrices involved. In order for matrix multiplication to be possible, the number of columns in the first matrix must be equal to the number of rows in the second matrix. If this condition is met, then the multiplication is considered correct. Otherwise, it is not possible to perform matrix multiplication and it would be considered incorrect.
