A. The two listed added up will be 180 degrees.
5x - 57 + 3x + 5 = 180
8x - 52 = 180
8x - 52 + 52 = 180 + 52
8x = 232
x = 29
B. The two listed added up will be 180 degrees.
2x + 4x + 150 = 180
6x + 150 = 180
6x + 150 - 150 = 180 - 150
6x = 30
x= 5

Answer:
Option B is correct.
0.0166 is correct.
Step-by-step explanation:
The σrho is the standard error of the sample proportion and it is given as
σₓ = = √[p(1-p)/n]
where p = sample proportion = 55% = 0.55
n = sample size = 900
σₓ = = √(0.55×0.45/900) = 0.016583124 = 0.0166 to 3 s.f.
Hope this Helps!!!
