Containers A and B each hold several balls. Once a second, one of the balls is chosen at random and switched to the other container. After a long time has passed, you regularly record the number of balls in each container every second. In 8 x 105 seconds, you observe 3125 instances when container A held all the balls while container B was empty. Required:
a. How many balls are there?
b. What is the most likely number of balls to be found in one of the containers?

Acircle has a radius of 5/6 units and is centered at (3.6, 7.8) write the equation of this circle

How do i make someone brainliest? (if you answer me, i might be able to make you brainliest! )

Girardo is using the model below to solve the equation . girardo uses the following steps: step 1 add 4 negative x-tiles to both sides step 2 add 1 negative unit tile to both sides step 3 the solution is which step could be adjusted so that gerardo's final step results in a positive x-value? in step 1, he should have added 4 positive x-tiles to both sides. in step 1, he should have added 3 negative x-tiles to both sides. in step 2, he should have added 4 negative unit tiles to both sides. in step 2, he should have added 1 positive unit tile to both sides.
