the probability of the two
boys sitting in the middle

the probability of Frida
and Natalie sitting
together
the probability of Robbie
sitting between the girls
the probability of Natalie
sitting between Dave
and Robbie

step-by-step explanation:

hiking down a winding trail.

step-by-step explanation:

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.
