After law school, you visit an island where everybody is a truth-teller or a liar, and get caught up in a criminal trial. The prosecutor, who is either a truth-teller or liar herself, says: X is guilty. X and Y are not both guilty. Can we determine who is guilty and who is innocent?

No, we cannot determine who is guilty and who is innocent.

Step-by-step explanation:

The prosecutor is either a truth teller or a liar.

The probability of her telling the truth is 0.5, which is the same probability of her telling lies.

Now, she said: X is guilty.

We cannot determine who is guilty and who is innocent, because X and Y both have equal chances of being guilty or innocent, which is due to the equal chances of her telling the truth, and telling a lie.

i believe the answer to be 48

step-by-step explanation:

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
