Graphs can be used to model real-world situations
- Segment 8 means: people are leaving the arena
- Segments 5 and 7 represent, intervals where there was no incoming or outgoing fans.
- Segment 6 means a few people left, when the game was going to an end.
Segment 8
From the graph (see attachment), we have the following observations
- Segment 8 is at the second half of the graph
- Segment 8 connects segment 7 and 9 (i.e. from the top, downwards)
The above points imply that:
Fans are leaving the arena at segment 8
Segments 5 and 7
From the graph, segments 5 and 7 are horizontal lines.
This means that:
No entry or exit was observed by the fans, at segments 7 and 5
Segment 6
Segment 6 connects segments 5 and 7, with a short downward line
This means that:
Few people left the arena, at segment 6

Answer:
97
Step-by-step explanation:
It is given that a figure skater needs a total score of at least 90 to move on to the next round.
The first three judges’ scores were 83, 88, and 92.
Let x be the score given by fourth judge.
Formula for average:
where, n is the number of observations.
Average of four judges is
Average score must be at least 90.
Multiply both sides by 4.
Subtract both sides by 263.
Therefore, the minimum score the fourth judge could have given is 97.
