A researcher studies the relationship between the number of hours of sleep per night and the performance on a memory test Study participants are randomly selected to get no sleep or sleep in
1-hour increments, up to 8 hours total (that is, the participant gets 1 hour, 2 hours, and so on, up to 8 hours of sleep). The researcher determines that the association between the two variables
can be modeled with the linear equation p = 9h + 15, where his number of hours of sleep and p is the percentage score on the memory test Use the slope in the equation to describe the
association between the hours of sleep and the performance on the memory test

y > 1/3x

y < = -x + 4

hope this : )

answer: 10 meter

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.
