What is -3 + 1/2 n = 1/2 (-n + 14)

n=10

Step-by-step explanation:

first distribute

-3 + 1/2 n = -1/2n + 7

next multiply both sides of the quation by 2

-6+n=-n+14

add n to both sides

-6+n+n=14

add 6 to both sides

n+n=14+6

combine like terms

2n=20

divide both sides by 2

n=10

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%
