Step-by-step explanation:
The population size is everybody running the race. It does not include people watching the race and it is not confined to just the 20 people the researcher talked to.
If it doesn't limit itself to the 20 people, then the 5 and 12 and 3 people are also too limiting.
Answer:
63+ 2x- 17 = 180 degree
or, 2x+46=180degree
or, 2x=180-46=134degree
or, x = 134÷2=67 degree ans.
Answer:
(7, -1)
Step-by-step explanation:
Look at vertex R. The x is 7. Q has the same x value as R and same Y value as P.
Answer:
x = 17
Step-by-step explanation:
77° + (6x + 1)° = 180° (angels on a straight line)
Solve for x
77 + 6x + 1 = 180
Add like terms
6x + 78 = 180
6x + 78 - 78 = 180 - 78
6x = 102
6x/6 = 102/6
x = 17
