3

Step-by-step explanation:

Given:

If fifteen less than two times a number is divided by six more than the number, the result is four less than 9 times the reciprocal of the number.

Question asked:

Find the number ?

Solution:

Let the number be

As given that:-

15 less than 2 times a number 6 more than the number = 4 less than 9 times the reciprocal of the number

Then the equation will be:-

By cross multiplication:-

By adding both sides by

Adding both sides by

Dividing both sides by 6

Taking root both sides

Thus, the number is 3.

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%
