Answer:

0.69

Step-by-step explanation:

Here, we want to find the probability that a randomly selected television is connected to the internet given that it is voice-controlled

let P(V) is the probability of selecting a voice controlled television

P(I) is the probability that a selected television is connected to the internet

So the probability we want to calculate according to Baye’s theorem will be;

P(I|V) = P(I n V)/P(V)

P( I n V) = 22%

P(V) = 32%

So the probability is;

22%/32% = 0.6875 which is approximately 0.69

What is diameter:

in geometry, a <u><em>diameter</em></u> of a circle is any straight line segment that passes through the center of the circle and whose endpoints lie on the circle. It can also be defined as the longest chord of the circle. Both definitions are also valid for the diameter of a sphere.

What is radius:

In classical geometry, a <u><em>radius</em></u> of a circle or sphere is any of the line segments from its center to its perimeter, and in more modern usage, it is also their length. The name comes from the Latin radius, meaning ray but also the spoke of a chariot wheel.

Explanation:

The <u><em>diameter </em></u>is the line that goes across the center of the circle and double the <u><em>radius</em></u> which is half, therefore <u><em>KR</em></u> is the <u><em>correct answer.</em></u>

Answer:

<u><em>KR, D, or the last option.</em></u>

Statement answer:

<u><em>Segment KR is the Diameter of Q.</em></u>
