Question 1:

(attached is a graph of the data)

The graph seems to show a negative trend. Each value is usually less than the value before it.

People may only want to see the first game and decide to not show up to any others. Or maybe, as more games occurred, the weather was colder and people didn't want to go out in the cold.

Question 2:

  • St John's    | 174000 | 173000
  • Sudbury     | 165000 | 155000
  • Saint John | 126000 | 123000
  • Chicoutimi | 160000 | 155000
  • Thun. bay  | 127000 | 122000
  • Regina       | 194000 | 193000
  • Trois-Riv.   | 140000 | 138000

(attached is a graph of the data)

I chose this graph type to demonstrate each city, as well as the change in population over time.

I notice that, for each city, the population decreased slightly from 1996 to 2001.

The graph shows the trend because the pink bar (2001) is lower than the orange bar (1996).

Predicting values for 2006:

  • St John's    | 172000
  • Sudbury     | 145000
  • Saint John | 120000
  • Chicoutimi | 150000
  • Thun. bay  | 117000
  • Regina       | 192000
  • Trois-Riv.   | 136000

To find these values, I found the difference from 1996 to 2001 (<em>for St John's: </em>174000-173000 = 1000). Since 1996 to 2001 is 5 years, and 2001 to 2006 is also 5 years, I can subtract 1000 from 2001's value (173000 - 1000 = 172000). Another example (for Saint John): 126000 - 123000 = 3000. 123000 - 3000 = 120000.

Fill in the blank with the appropriate angle:
Gre4nikov [31]

Answer:

<h2>∠DHG</h2>

Step-by-step explanation:

Same side interior angles refers to the pair of angles which are inside the two "parallel" lines and at the same side of the transversal line.

Notice that angles BGH and DHG are same side interior angles. Similarly, angles AGH and CHG are also same side interior angles.

Therefore, the right answer is ∠DHG.
