example of nither symmetric and nor skew symmetric mat

1. A square matrix A is said to be skew-symmetric if A ' = -A. 2. The diagonal elements of a skew-symmetric matrix are all ze..

A square matrix A = [a i j ] is said to be skew-symmetric if the (i,j) t h element of A is the negative of the (j,i) t h element of A i.e., if a i j = -a j i for all i, j. In particular, for i = j, we have Thus the diagonal elements of a skew symmetric ma..

Which of the following statement(s) can be inferred from a box plot? I. In a box plot, if the median falls to the left of the center of the box, then the distribution is negatively skewed. II. If the median is near the center of the box, the distribution is approximately symmetric..

The average price of the suburban station wagon is $20,000 with a standard deviation of $2000. The median price of the suburban station wagon is $18,000. Find the coefficient of skewness and describe the shape. => 0, symmetric or - 3, negatively skewed or + 3, positive..

skew-symmetric for every square matrix A. That is any square matrix is expressible as the sum of a symmetric matrix and a skew-symmetric matrix. 5. A matrix which is both symmetric and skew symmetric is a zero matr..

>If any two rows or columns of a determinant are equal, then its value is zero. If each element of a row or column of a determinant multiplied by k, then its value is multiplied by k. If two rows or columns of determinant are proportional, the value of the determinant is zero. A square A = [a i j ]..
