Answer:

x = 14

Step-by-step explanation:

1. We know that all angle measures in a triangle sum to 180 degrees.

  • This means that 7x - 11 + 5x - 2 + 2x - 3 = 180.

2. (Solving)

Step 1: Combine like terms.

  • (7x+5x+2x)+(-11-2-3)=180
  • 14x -16 = 180

Step 2: Add 16 to both sides.

  • 14x - 16 + 16 = 180 + 16
  • 14x = 196

Step 3: Divide both sides by 14.

  • \frac{14x}{14}=\frac{196}{14}
  • x = 14

Step 2: Check if solution is correct.

  • 7(14)-11+5(14)-2+2(14)-3=180
  • 98-11+70-2+28-3=180
  • 180=180

Therefore, the answer is x = 14.

Answer:

An ANOVA test

Step-by-step explanation:

You will use the ANOVA test, which is a test that compares the means of more than 2 samples.  Since the teacher used 3 test groups, she would have to use this test if she wanted to do a hypothesis test to determine if the means are equal.  

*This test only tells us if the means are equal, it won't say which is greater than the other.  You would have to do 3 individual hypothesis tests comparing 2 means at a time in order to determine that.
