Which is the answer?

(a)= the third one  (b)= The last one

Step-by-step explanation:

One unit to the left of -8 gives you the first part which is -8.  Then one unit to the left must be a negative and is therefore -1.

Like above the first number is -8.  Since you're moving to the right, it has to be a positive making it +1.

d.192

step-by-step explanation:

12*16=192

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.
