Answer:
96 questions
Step-by-step explanation:
Given that:
Total number of questions = 120
Percentage questions completed = 80%
Number of questions completed =?
Number of questions completed = total number of questions * percentage questions completed
Number of questions completed = 120 * 0.8
Number of questions completed = 96
Answer:
Step-by-step explanation:
4 g.
c=42
a=b=d
a+b+42=180
a+a=180-42
2a=138
a=138/2=69
a=69
b=69
c=42
d=69
5a.
a=30
angle O=180-(a+30)=180-(30+30)=180-60=120°
d=80
angle O=180-(d+80))=180-(80+80)=180-160=20°
central angle O of middle triangle=180-(120+20)=180-140=40°
b=c
b+c+40=180
b+b=180-40
2b=140
b=140/2=70
b=70°
c=70°
1856x^2 - 6032x + 4176 hope it helps if you dont understand ask me anything!
If its a normal distribution that would be 34.1%
