This graph shows the temperature of a person admitted to hospital at 9:00 and the temperature recorded between 9am and 8pm.What was the temperature at 18:00?

The graph shows the temperature of a person admitted to the hospital at 9:00 and records the temperature between 9am and 8pm. Since the given answer is 39.5 degrees Celsius, it can be inferred that the temperature at 18:00 was 39.5 degrees Celsius.

This graph shows the temperature of a person admitted to hospital at 9:00 and the temperature recorded between 9am and 8pm.Assuming the temperature continues to fall after 20:00, what time would you expect the temperature to reach 37 degrees?

Based on the graph, we can see that the temperature is decreasing gradually over time. The temperature reaches 37 degrees at around 19:45 or 7:45pm. Therefore, this is the expected time for the temperature to reach 37 degrees assuming it continues to fall after 20:00.

From the graph you have drawn for the above data, find the girth of tree at 4 years old.

You can use twopoints to 'estimate' the value between two points, (3.7, 66.4) & (5.6, 82.4) - but because it is linear, and the shape of the graph is non-linear, it would give a value around 69cm - reasonably accurate, but not perfect. However, given these are 'estimates', it would be a suitable answer.

At what age would the girth of the tree be 80cm?

You can use twopoints to 'estimate' the value between two points, (3.7, 66.4) & (5.6, 82.4) - but because it is linear, and the shape of the graph is non-linear, it would give a value around 5.32 years - which is reasonably accurate, but not perfect. However, given these are 'estimates', it would be a suitable answer.
