Suppose a has reduced row echelon form equal to the n×n identity matrix and in order to reduce it to this rref you have to use r row swaps (the pij operations), and m operations of multiplying a row by a nonzero scalar where the scalars involved during the process were α1, α2, . . , αm. in addition you also use an unspecified number of operations of the type aij (c) of adding a multiple of one row to a distinct row during the reduction process. describe a formula for d = det(a) in terms of the variables n, r, m, α1, . . , αm and explain how you got your answer

x=17

step-by-step explanation:

solve 3x-24=x+10

then that makes it 2x=34 because you subtract an x from both sides to get rid of the one on the right, and then you add 24 to both sides to get rid of the 24 on the left

divide by both sides by 2 to get your answer so that you can get your answer

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.
