Answer:
The radius of circle O is 8.5 Units
Step-by-step explanation:
Solution
The radius of a circle is refereed to as the half of the diameter.
Now,
On how to figure out the length of AB, we apply the Pythagorean's equation or formula which is given below
Thus,
a² + b² = c²
(15)² + (8)² = c²
225 + 64 = c²
√289 = √c²
Then
c = 17
What this shows is that AB is 17 units.
Since we have gotten the diameter, the next step is to divide into half the know the radius value
Therefore,
17 ÷ 2 = 8.5 Units
= 8.5 Units.

Answer:
<h2> B and C are not independent events </h2>
Step-by-step explanation:
This is a probability question, basically on independent events.
B and C are said to be independent if the occurrence of either event does not affect the occurrence of the other.
And now considering the fact that C will always present a head any way anyhow, the occurrence
of C will affect the outcome of B and C.
<em>Hence B and C are not independent events</em>
