Answer:
Step-by-step explanation:
We need to find the equation of the circle. First, the formula:
Where (h,k) is the center and r is the radius
The center is (5,-4), so we can say:
Now, to find the radius, we can use the distance formula to find distance between (5,4) and (-3,2).
The distance formula is
Where
x_1 = 5
x_2 = -3
y_1 = 4
y_2 = 2
Plugging in, we get:
Hence, the radius is 10 and we can write the equation of circle as:
A = event that a male highschool player plays on a college team
B = event that a female highschool player plays on a college team
C = event that a male college player is drafted by the pro leagues
D = event that a female college player is drafted by the pro leagues

Going from high school to college:
P(A) = 4500/549500
P(A) = 0.0082 <<-- value is approximate
P(B) = 4100/456900
P(B) = 0.0090 <<-- value is approximate
Females have a better chance of playing on college teams (since 0.0090 is larger than 0.0082)

Going from college to the pro leagues:
P(C) = 44/4500
P(C) = 0.0098 <<-- value is approximate
P(D) = 32/4100
P(D) = 0.0078 <<-- value is approximate
Males have a better chance of getting drafted by the pro leagues (since 0.0098 is larger than 0.0078)
We know the perimeter is the sum of all sides. So lenght+length+width+width = 2length+2width.
Let's call the width x. If the length is 4m longer, then it's x+4.
We know the perimeter, so we can make an equation:
56=2x+2(x+4)
And solve from there:
56=2x+2x+8
56=4x+8
48=4x
48/4=x
x=12
The width, which is x, is 12 m. And the length, x+4, is 16 m.
You can check this is correct by calculating the perimeter using those values: 12+12+16+16=56.
