ii) (d)
iii) (b)
iv) (a)
3.
ii) 80°
Step-by-step explanation:
2.
i) 2x+x+3x=180°
x=30°
ii) x+110=180
x=70
iii) x+2x+30°=180
x=50°
iv) 2x+15°+45°+x=180
3x+60°=180
x=40°
3.
ii) 2x+5+25=180°
2x+30°=180°
x=75°
the measure: x+5°= 75°+5°=80°
Answer:
The value is 
Step-by-step explanation:
From the question we are told that
The population proportion is 
The sample size is n = 343
Generally given that the ample size is large enough , i.e n > 30 then the mean of this sampling distribution is mathematically represent

Generally the standard deviation is mathematically represented as

=>
=> 
Generally the the probability that the sample proportion will differ from the population proportion by less than 4% is mathematically represented as



=> 
From the z table the area under the normal curve to the left corresponding to 1.887 and - 1.887 is

and

So

=>
