Amanager is considering three new machines for filling boxes of cereal at a processing plant. each of the three machines is assigned to 10 randomly selected employees. the time required to fill 25 boxes using the machine is recorded. how many treatments does this single-factor experiment have?
a. 3
b. 10
c. 1
d. 25

3

Step-by-step explanation:

Given that a manager is considering three new machines for filling boxes of cereal at a processing plant. Each of the three machines is assigned to 10 randomly selected employees

Here the treatments are the no of machines. i.e. three machines are three treatment.

After selecting treatments 25 boxes using each machine is recorded.

Hence this is a one factor anova with three factors namely three machines affecting the result

Hence no of treatments = 3

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.
