Translate the quotient of 12 and the sum of a number and 4

12/(n +4)

Step-by-step explanation:

"The quotient of x and y" is usually translated to mean x/y.

"The sum of a and b" is translated to mean "a+b".

Here, you want the quotient of a number (12) and a sum ("a number" and 4). It can be convenient to let "n" stand for "a number." Then the sum is (n+4), and the quotient is ...

... 12/(n +4)

step-by-step explanation:

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.
