Ines created a coefficient matrix to represent the system of linear equations below.
3x=3
4y = 8
-9z=-27
which type of matrix did ines create?
o
a 3x1 matrix
a 3x2 matrix
an augmented matrix
a diagonal matrix

The answer is a 3x2 matrix

Step-by-step explanation:

From the given system of equation

The parameters of the variables x, y and z are outlined as the first column

And the integers on the other side are outline as the second column

This makes the matrix a 3rolls and 2 column matrix

tigers

step-by-step explanation:

cougars 12/10 (12-10 = 2)

bobcats 20/10 (20-10 =10)

bulldogs 8/5 (8-5 =3)

tigers 3/5 (3-5 =-2)

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.
