FAST PLEASE HELP You've taken a random sample of beaches in the United States and measured their
lengths. A hypothetical probability distribution for beach length is represented in the
table below. What's the probability of a randomly selected beach having a length of
9 miles?

X (lengths in miles
0-3
3-6
6-9
9-12
12-15

p(x)
.1
.20
.25
.35
.10

Options:
A. .35
B. .60
C. .25
D. .45
None of the above

center= (-2,0)

radius= sqrt2/2

step-by-step explanation:

"if it is my birthday, then it is snowing"

center (1,3) with radius 6

step-by-step explanation:

we must complete the square to find the center and radius of the circle.

first make sure the x and y squared terms have 1 as their coefficients. we also make sure x and y terms together.

we now create space between the x and y terms with parenthesis.

we complete the square by taking the middle terms -2x and the -6y - divide each and square them.

we add the squares to both sides.

simplify.

and write the quadratics in factored form.

the center is (h,k) or (1,3). the radius is the square root of 36 which is 6.
