In a corporate environment, a network administrator is tasked with managing user access to a video conferencing system. The system requires that users be assigned roles based on their job functions, which include Administrator, Moderator, and Participant. Each role has specific permissions: Administrators can manage user accounts and settings, Moderators can control the meeting environment, and Participants can only join meetings. If the company has 150 employees, and the administrator decides to allocate 20% of the employees as Administrators, 30% as Moderators, and the remaining as Participants, how many users will be assigned to each role?
