Answer:
(2) 4, 7, 9; 2, 5, 6; 1, 3, 8
Step-by-step explanation:
Let's group them based on how many lines they have inside the shape...
0 lines: 4, 7, 9
2 lines: 2, 5, 6
3 lines: 1, 3, 8
Therefore the answer is (2) 4, 7, 9; 2, 5, 6; 1, 3, 8
2x + 12 = 20
2x = 32
32/2x
X= 16
Answer:
the equation is 110=19x-4
Step-by-step explanation:
the angels shown are vertical angles meaning they are congruent so they are equal to each other
8 and 32.
8 times 4 = 32
32 - 8 = 24
4x - x = 24.

Answer:
The critical value for the 95% confidence interval is z = 1.96.
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
So it is z with a pvalue of 
, so z = 1.96.
The critical value for the 95% confidence interval is z = 1.96.
