Answer:
81 games
Step-by-step explanation:
Given
![P(Red) = 0.45](https://tex.z-dn.net/?f=P%28Red%29%20%3D%200.45)
![P(Blue) = 0.40](https://tex.z-dn.net/?f=P%28Blue%29%20%3D%200.40)
![n = 180](https://tex.z-dn.net/?f=n%20%3D%20180)
Required
Expected game the red team will win
Expected number is calculated as:
![E(x) = n * P(x)](https://tex.z-dn.net/?f=E%28x%29%20%3D%20n%20%2A%20P%28x%29)
In this case, the number of winnings for the red team is:
![Expected = 180 * P(Red)](https://tex.z-dn.net/?f=Expected%20%3D%20180%20%2A%20P%28Red%29)
![Expected = 180 * 0.45](https://tex.z-dn.net/?f=Expected%20%3D%20180%20%2A%200.45)
![Expected = 81](https://tex.z-dn.net/?f=Expected%20%3D%2081)
Answer:
Circular shapes - They are those planner shapes that represent the locus of all the points that has a constant distance from a fixed point on the plane. This constant distance is termed as the radius of the circle and the fixed point is known as the center of the circle.
The center of the circle is enclosed by all the points on its periphery.
The circumference of the circle is the total length of its periphery around the center.
Concentric circles are two circles that have the same center

The ship is 394.73 fr far from the base of the lighthouse.
According to the given question.
Angle of depression from the top of the light house is 21 degrees.
Let ∠ABC represents the angle of depression. And BC be the distance of ship from the base of light house.
Now in triangle ABC we have
tan 21 = AC/BC
⇒ 0.38 = 150/BC
⇒BC = 150/0.38
⇒ BC = 394.73ft
Hence, the ship is 394.73 fr far from the base of the lighthouse.
