What are the solution(s) to the quadratic equation x2 - 25 = 0?
x= 5 and x = -5
o x = 25 and x = -25
o x = 125 and x = -125
o no real solution

A

Step-by-step explanation:

Given

x² - 25 = 0 ( add 25 to both sides )

x² = 25 ( take the square root of both sides )

x = ± = ± 5

Solutions are x = 5 and x = - 5

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%
