In Mr. Johnson’s third and fourth period classes, 30% of the students scored a 95% or higher on a quiz. Let be the total number of students in Mr. Johnson’s classes. a. If 15 students scored a 95% or higher, write an equation involving that relates the number of students who scored a 95% or higher to the total number of students in Mr. Johnson’s third and fourth period classes.

b. Solve your equation in part (a) to find how many students are in Mr. Johnson’s third and fourth period classes.

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%
