Selena is graphing the inequality x less-than negative 2. She begins by drawing a number line and placing an open circle at –2.

A number line going from negative 7 to positive 3. An open-circle is at negative 2.

Which could be Selena’s next step?
-shading the number line to the left of the open circle.
-shading the number line to the right of the open circle.
-shading the number line to the right and left of the open circle.
-shading in the open circle.

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.

i dont know sorry

step-by-step explanation:

not only in mathematics, scientific proof also are required in the other field of science. also maths proofs are of particular structure, containing steps and logics. so proving is like doing science, it is science. that's why it is important to prove. 

an inaccurate proof leads to errors, or stating results that are not accurate.  which wil mess the probelm up you dont want this

the answer is 13/48
