Mr. Sullivan places tiles numbered 1 through 18 in a bag and assigns a number to represent each of the 18 students in his class. Students will present their final reports in the order that their assigned tiles are drawn from the bag. Is Mr. Sullivan being fair? Use the drop-down menus to explain your answer. Mr. Sullivan being fair because one tile has probability of being selected over another tile.

Mr. Sullivan is being fair because one tile has an equal probability of being selected over another tile.

Step-by-step explanation:

The process is fair because every tile has the same probability of being selected, and as the selection goes on, the selected students are removed.

u = -(6/7)w

step-by-step explanation:

place all values with 'u' on one side of the equation.

4u + 8w = - 3u + 2w

4u + 3u = 2w - 8w

further simplify the equation by solving the addition and subtraction.

7u = - 6w

make 'u' the independent variable by placing its co-efficient on the right-hand side.

u = - (6/7)w
