Answer:

<em>Hello There If you want to learn of the equation of the circle. Look at the circle first then.. The center-radius form of the circle equation is in the format will help you from that point. with the center being at the point (h, k) and the radius being "r". This form of the equation is really helpful, since you can easily find the of center and the radius.</em>

Hope it helps!

Circle Equation: (x - h)² + (y - k)² = r²

(h, k) = center

r = radius

The center can be found at the point (2, -3)

The radius is 2 units.

Substitute these values into the equation:

(x - 2)² + (y + 3)² = 2²

(x - 2)² + (y + 3)² = 4

Therefore, the answer is [ (x - 2)² + (y + 3)² = 4 ]

Best of Luck!

To control the traffic during Ramadan month, a Police Sergeant is assigned to control the traffic

m_a_m_a [10]

To complete the table it is necessary to know the possibilities that the sergeant has to change or remain in an intersection. The probabilities (depending on the box) are:

0
0.2
0.25
0.33

<h3>How to calculate the probability of intersection change? </h3>

To know the probability of intersection change, it is necessary to locate the police officer at one of the intersections. Subsequently, count how many possibilities of change you have, for example: 3 possibilities and finally add the possibility of remaining in the intersection as shown below:

Intersection 3 has 3 possibilities of changing towards intersections 2, 8 and 4. Additionally, it has the possibility of staying at intersection 3, that is, it has 4 possible decisions.

To know the probability we divide the number 1 (because it is only a decision that we have to make) and divide it by the number of possibilities (4).

1 ÷ 4 = 0.25

According to the image we can infer that in some intersections they only have 3, 4 and 5 possibilities, so the probability of change will be different as shown below:
