The robot solves a Rubiks Cube in 20 moves. But it is only correct 60% of the time. If the robot makes 125 attempts, how many times would you expect it to correctly solve the puzzle?

So the question is asking what 60% of 125 is:

60% * 125

60/100 * 125

7500/100

= 75.

You can expect it to correctly solve the puzzle 75 times.

option 1 is correct.

step-by-step explanation:

y varies inversely with x and constant of variation is 4

the equation will be:

y = k/x

where k =4 so,

y = 4/x

if we put values of x of option 1 in the above equation and find values of y

y = 4/-2 => y =-2

y = 4/-1 => y = -4

y = 4/1 => y = 4

y = 4/2 => y =2

so, all the values of x and y are correct.

if we put values of x given in other options and find value of y we cannot find whole table satisfying the equation.

hence option 1 is correct.
