Describe what partial and transitive dependencies are
What will be an ideal response?
A partial dependency is when the field only depends on one part of a composite or concatenated key. In other words, the field is determined by only one piece of a multi-field key. A transitive dependency is when a field depends on another field in the table which then that field depends on a candidate key, A?B and B?C, thus A implies C. If C is a candidate key and B is not a candidate key, this is a transitive dependency.

Which of the following statements is false?
a. A runnable thread can enter the timed waiting state for a specified interval of time. It transitions back to the runnable state when that time interval expires or when the event it’s waiting for occurs. b. Timed waiting threads and waiting threads can use a processor, if one is available. c. A runnable thread can transition to the timed waiting state if it provides an optional wait interval when it’s waiting for another thread to perform a task. Such a thread returns to the runnable state when it’s notified by another thread or when the timed interval expires—whichever comes first. d. Another way to place a thread in the timed waiting state is to put a runnable thread to sleep—a sleeping thread remains in the timed waiting state for a designated period of time (called a sleep interval), after which it returns to the runnable state.
