Mary wanted to solve the system of equations shown. She first used row reduction to get the system into 2 equations with 2 variables x and y. she then used her calculator and got the graph shown what is the solution to her system

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.

the answer is simply just 6n add the two together as they have an n

they charge the same amount at 20 minutes.
