To determine whether the boundary point \( z = 3 \) is included in the solutions to the inequality \( -10z > -30 \), we should first consider what the boundary point \( z = 3 \) represents.

The equation \( -10z = -30 \) simplifies to \( z = 3 \), which is the point where the inequality changes from true to false.

Since the original inequality is strict (using "greater than" rather than "greater than or equal to"), the boundary point itself (3) does not satisfy the inequality.

So the answer is **No**, \( z = 3 \) is not a solution to the inequality \( -10z > -30 \).
