After learning the theoretical probability of a two sided coin landing on any one side, students work in groups to flip the coin
several times and get the following: 9 heads and 6 tails. Based on the scenario, which of the observations made by students about probability is accurate? A. The theoretical probability of a coin's landing on heads, 0.5, is equal to the experimental probability obtained B. The theoretical probability of a coin's landing on heads is less than the experimental probability obtained.

Answer:
Step-by-step explanation:
Assuming this complete problem: "A cell tower is located at (-8, 4) and transmits a circular signal that covers three major cities. The three cities are located on the circle and have the following coordinates: G (-4, 7), H (-13, 4), and I (-8, -1). Find the equation of the circle"
For this case the generla equation for the circle is given by:
From the info we know that the tower is located at (-8, 4) so then h = -8 and k = 4, so then we need to find the radius. So we have the equation like this:
If the 3 points are on the circle then satisfy the equation. We can use the first point (-4,7) and if we replace we can find the value for
So then
And if we replace the second point we got this:
And for the third point we have:
And we got the same result.
So then our final equation is given:
