If the mean of 5, 11, 6, 4, 7, P and 10 is 8, find the value of (P)​

(p+5+11+6+4+7+10)/7=8

Step-by-step explanation:

p+43/7=8

p+43=8*7

p+43=56

p=56-43

p=13

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.
