6. Suppose 60 students are candidates for four scholarships – one for $500, one for $750, one for $1000 and the fourth for $1200: a. How many way can four students get selected from the 60 candidates? b. If you, your brother, and two sisters are four of the 60 candidates, what is the probability all four of you will get the four scholarships?

it alot will look like this 4.4

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.
