Question

The graph shows tide heights from a location in Canada.

Based on the trend shown by the data, which predictions can be made? Check all that apply.

After 10:48 p.m., the tide height will rise.
The next high tide height will be higher than 12 m.
If the graph continued, the next line would go up.
After 10:48 p.m., the tide height will continue to fall.
If the graph continued, the next line would go down.

Answer 1

Based on the trend shown by the data, the tide height will continue to fall and the next line on the graph would go down.

Step-by-step explanation:

Based on the trend shown by the data, the predictions that can be made are:

• After 10:48 p.m., the tide height will continue to fall. The graph shows a decreasing trend in tide height after this time.
• If the graph continued, the next line would go down. The downward trend in tide height suggests that the next line on the graph would continue to descend.

The prediction that the tide height will rise after 10:48 p.m. and that the next high tide height will be higher than 12 m cannot be made based on the trend shown by the data.
