Which of the following statements are true? all square matrices are diagonal matrices. all diagonal matrices are square matrices. the size of any square matrix is m x m, where m is a positive integer. all coefficient matrices are square matrices.

All diagonal matrices are square matrices.

The size of any square matrix is m x m, where m is a positive integer.

the 2 figures are congruent bc if you reflect abcd over the y axis then over the d axis the figures overlap

15%

step-by-step explanation:

use the table and count the number of guesses that has two correct answers.

the following are two correct answers

10010, 01100, 11000

a total of 3 numbers having 2 correct guesses out of 20 questions.

probability of getting 2 correct guesses = the number of questions getting 2 correct answers / total number of questions.

= 3/20

to convert it into percent multiply by 100, we get

= 3/20 * 100

= 15%

the answer is 15%

you.
