the answer is the square of 13

Step-by-step explanation:

a= 2 and b=3, square both and that equals 4 and 9. using pythagorean theorem 4+9=12=the distance between a and b :D

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.

so, converting firstly the mixed fractions to improper fractions and then "adding".
