False ....a parameter is something YOU can change, like asking magazines if they are interested in sports, or interested in photography, or something else. So the 12% is a statistic.

Answer:
B
Step-by-step explanation:
Given
7x - 9 > 2x + 6 ( subtract 2x from both sides )
5x - 9 > 6 ( add 9 to both sides )
5x > 15 ( divide both sides by 3 )
x > 3 → B
Let's see if we can find a pattern:
Row number 1 has 
seats
Row number 2 has 
seats
Row number 3 has 
seats
Row number 4 has 
seats
Can you see the pattern? After 
rows, we have added 
seats.
So, the 60th row will have
6 ≤ 4 + (-2x)
6 (-4) ≤ 4 - 2x - 4
4 and 4 cancels out
2 ≤ -2x
-1≥x
When you divide by a negative number, the inequality sign turns to the other side.
