The robot solves a Rubik's cube in an average of 20 moves. But it's correct only 60% of the time. If the robot makes 125 attempts, how many time would you expect it to correctly solve the puzzle

75

Step-by-step explanation:

Let x represent number of times robot will correctly solve the puzzle.

We have been given that the robot solves a Rubik's cube in an average of 20 moves. But it's correct only 60% of the time. We are asked to find the number of times robot will correctly solve the puzzle in 125 attempts.

We will use proportions to solve our given problem as ratio between two proportion quantities is same.

Let us find 60% of 20.

Therefore, the robot will solve 75 puzzles.

in problems involving proportions, we can use cross products to test whether two ratios are equal and form a proportion. to find the cross products of a proportion, we multiply the outer terms, called the extremes, and the middle terms, called the means.
