- If, for instance, you wish to examine if a new category of baseball bat really does have an impact on notable features and the same individuals play once from the old bat and once with new bat, you also have a dependent sample.
- Since each player utilized both bats, there are two measured values for each player, all measured values are likewise accessible in pairs.

Answer:
178 - 3x.
Step-by-step explanation:
The three angles in a triangle add up to 180 degrees so an expression for the third angle is:
180 - (x + 9) - (2x - 7)
Distributing the negative over the parentheses, we have
180 - x - 9 - 2x + 7
= 180 - 9 + 7 - x - 2x
= 180 - 2 - 3x
= 178 - 3x (answer).
