The circle below is centered at the origin and has a radius of 10. What is its equation?

x²+y² = 100

Step-by-step explanation:

Equation for circle of radius r that is centered at (h,k):

(x-h)² + (y-k)² = r²

In your case, h=k=0 and r=10.

x²+y² = 100

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.
