In a television advertisement, a company called "waist away" claimed the workout program on their set of dvds would people lose weight more than any other dvd workout program. to test this claim, an independent company, called "slim down," selected one other dvd program. they then randomly assigned half the volunteers to the waist away program and the other half to the slim down program. each participant was weighed before they started the program and then regularly participated in their assigned program for one month. after one month, each participant was weighed again. the percent of weight lost was recorded for each person, where negative values indicated a weight gain. what type of study was performed?

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.

10 - 75

step-by-step explanation:

there's nothing attached so it's most likely anything in that range.
