What is the solution for this inequality? 8x < -32 a. x < -4 b. x < 4 c. x > -4 d. x > 4

For this case we have the following expression:

The x must be cleared, for which the 8 (which is multiplying to the x) is passed, to the other side of the inequality, dividing to -32. So, we have left:

Dividing we have:

So, the solution is

Option A

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%
