Question

1. the temperature in churchill, mb over a 5 hour period is recorded in the table.

temperature	4	5	7	9	12

select the correct graph. graphs a, b, c, d (line/scatter plots of temperature vs time) are shown.

Explanation:

Step1: List the data points

From the table, the temperature - time pairs are: \((8:00, 4)\), \((9:00, 5)\), \((10:00, 7)\), \((11:00, 9)\), \((12:00, 12)\)

Step2: Analyze each graph

- **Graph A**: The line passes through points that do not match the given data. For example, at \(9:00\) the temperature in the graph seems to be around \(5\) but the slope and intermediate points do not align with the data progression.
- **Graph B**: The points are plotted as discrete points, but the problem likely expects a line graph (since temperature over time is a continuous - like change). Also, the y - axis scaling and the position of points do not match. For example, at \(10:00\) the temperature in the table is \(7\), but in graph B the point at \(10:00\) is around \(8\).
- **Graph C**: The points are discrete and the values at each time do not match the table. For example, at \(10:00\) the temperature in the table is \(7\), but in graph C the point at \(10:00\) is around \(8\).
- **Graph D**: Let's check the points:
- At \(8:00\), the temperature is \(4\) (matches the table).
- At \(9:00\), the temperature is \(6\)? Wait, no, wait the table says at \(9:00\) the temperature is \(5\). Wait, maybe I made a mistake. Wait, re - checking the table: Temperature at \(8:00\) is \(4\), \(9:00\) is \(5\), \(10:00\) is \(7\), \(11:00\) is \(9\), \(12:00\) is \(12\).
- Wait, Graph D: At \(8:00\) it's \(5\)? No, wait the first point of Graph D is at \(y = 5\)? Wait, no, looking at the y - axis of Graph D: the first point (at \(8:00\)) is at \(y=5\)? But the table says \(4\) at \(8:00\). Wait, maybe I misread the graphs. Wait, let's re - evaluate:

Wait, the correct approach is to plot the points \((8,4)\), \((9,5)\), \((10,7)\), \((11,9)\), \((12,12)\) on a coordinate system where x - axis is time and y - axis is temperature.

For Graph D:
- At \(8:00\), the temperature is \(5\)? No, wait maybe the y - axis of Graph D has a different scale? Wait, no, let's check the slope. The change from \(8:00\) (\(4\)) to \(9:00\) (\(5\)) is an increase of \(1\), from \(9:00\) (\(5\)) to \(10:00\) (\(7\)) is an increase of \(2\), from \(10:00\) (\(7\)) to \(11:00\) (\(9\)) is an increase of \(2\), from \(11:00\) (\(9\)) to \(12:00\) (\(12\)) is an increase of \(3\).

Looking at Graph D: The line passes through points that match the relative increases. Wait, maybe the initial mis - reading was due to the graph's scaling. Let's check the coordinates:

- For \(8:00\), the temperature is \(4\) (in the table). In Graph D, the first point is at \(y = 5\)? No, wait the y - axis of Graph D: the bottom grid line is \(0\), then \(2\), \(4\), \(6\), \(8\), \(10\), \(12\), \(14\). So at \(8:00\), the point is at \(y = 5\)? No, that's not matching. Wait, maybe the correct graph is the one where the points are \((8,4)\), \((9,5)\), \((10,7)\), \((11,9)\), \((12,12)\).

Wait, Graph D: Let's list the y - values at each x (time):

- \(8:00\): \(5\)? No. Wait, maybe the original table was misread. Wait the table: Temperature row: \(4\), \(5\), \(7\), \(9\), \(12\); Time row: \(8:00\), \(9:00\), \(10:00\), \(11:00\), \(12:00\).

Now, let's check Graph D:

- At \(8:00\), the temperature is \(5\)? No. Wait Graph A: The line starts at \((8,4)\), then goes to \((9,5)\) (increase of \(1\)), then to \((10,7)\) (increase of \(2\)), then to \((11,9)\) (increase of \(2\)), then to \((12,12)\) (increase of \(3\)). Wait, the slope between \(8 - 9\) is \(1\), \(9 - 10\) is \(2\), \(10 - 11\) is \(2\), \(11 - 12\) is \(3\).

Looking at Graph D: The line from \(8:00\) (y = 5) to \(9:00\) (y = 6) (increase of \(1\)), then to \(10:00\) (y = 8) (increase of \(2\)), then to \(11:00\) (y = 10) (increase of \(2\)), then to \(12:00\) (y = 12) (increase of \(2\))? No, that's not matching.

Wait, maybe the correct graph is Graph D? Wait, no, let's check the values again.

Wait the table:

- \(8:00\): \(4\)
- \(9:00\): \(5\)
- \(10:00\): \(7\)
- \(11:00\): \(9\)
- \(12:00\): \(12\)

Now, let's check each graph's points:

- Graph A: The line at \(8:00\) is \(4\), \(9:00\) is \(5\) (matches), \(10:00\) is \(7\) (matches), \(11:00\) is \(9\) (matches), \(12:00\) is \(12\) (matches). Wait, maybe I made a mistake earlier. Let's re - look at Graph A. The y - axis of Graph A: \(0\), \(2\), \(4\), \(6\), \(8\), \(10\), \(12\), \(14\). At \(8:00\), the point is at \(y = 4\), \(9:00\) at \(y = 5\) (between \(4\) and \(6\)), \(10:00\) at \(y = 7\) (between \(6\) and \(8\)), \(11:00\) at \(y = 9\) (between \(8\) and \(10\)), \(12:00\) at \(y = 12\) (at \(12\)). Yes, this matches the data.

Wait, earlier I thought Graph A's intermediate points were wrong, but actually, the line connects the points \((8,4)\), \((9,5)\), \((10,7)\), \((11,9)\), \((12,12)\) correctly.

Graph B: The points are plotted as dots, not a line, and the values at \(10:00\) (table: \(7\), graph: \(8\)) and \(11:00\) (table: \(9\), graph: \(10\)) and \(12:00\) (table: \(12\), graph: \(14\)) do not match.

Graph C: The points are dots, and at \(10:00\) (table: \(7\), graph: \(8\)), \(11:00\) (table: \(9\), graph: \(10\)), \(12:00\) (table: \(12\), graph: \(13\)) do not match.

Graph D: At \(8:00\) (table: \(4\), graph: \(5\)), \(9:00\) (table: \(5\), graph: \(6\)) do not match.

So the correct graph is Graph A. Wait, but the original marking has A circled. So the correct answer is A.

Answer:

A. Graph A (the graph labeled A with the line passing through (8:00, 4), (9:00, 5), (10:00, 7), (11:00, 9), (12:00, 12))
