Answer:
Step-by-step explanation:
∠CAD is the central angle and ∠CBD is the inscribed/circumference angle which means that
∠CAD = 2(∠CBD)
So, If ∠CBD = 55° then ∠CAD = 110°

Answer:
B: 0.15
Step-by-step explanation:
Answer:
0.8
Step-by-step explanation:
The question here says that In a class of 30 students, 18 are men, 6 are earning a B, and no men are earning a B. If a student is randomly selected from the class, find the probability that the student is a man or earning a B.
Since the question says that 18 out of 30 students are men,6 out of the remaining people earn a "B" and non of the 18 men earn a "B".
The probability of picking a man or a person that earns a "B" is
18/30 (since there are 18 men out of the 30 students)
And 6/30(since there are 6 people that earn a "b")
The probability of picking a man or a "b" earner is
18/30 + 6/30
= 24/30 or 0.8
