13. In an experiment to see whether the amount of coverage of light-blue interior latex paint depends either on the brand of paint or on the brand of roller used, one gallon of
each of four brands of paint was applied using each of three brands of roller, resulting
in the following data (number of square feet covered).

a. Construct the ANOVA table. (Hint: The computations can be expedited by
subtracting 400 (or any other convenient number) from each observation. This
does not affect the final results.)
b. State and test hypotheses appropriate for deciding whether paint brand has any
effect on coverage. Use a = 0.05.
c. Repeat part (b) for brand of roller.

  the correct choice is marked

step-by-step explanation:

the first two graphs show multiple turning points. the last graphs matches the description in every detail.

answer: yes, since the line has a steeper rate of change than the exponential the y-values will be greater and they will only intersect one time.

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.
