5x^2=60-20x is rewritten as 5(x-p)^2+q=0 what is the value of Q

-80

Step-by-step explanation:

5x² + 20x - 60 = 0

5(x² + 4x) - 60 = 0

5[x² + 2(x)(2) + 2² - 2²] - 60 = 0

5(x - 2)² - 5(4) - 60 = 0

5(x - 2)² - 20 - 60 = 0

5(x - 2)² - 80 = 0

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%
