There are 13 dogs at the dog park on a busy Saturday. 1 of them is a labrador retriever. What is the probability that a randomly selected dog is a labrador retriever?

there is a 1/13 (one in 13) chance that they will randomly pick a labrador.

Step-by-step explanation: If you need more help just message me :)

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.
