Answer:

(x-4) ^2 + (y+1)^2 = 81    

Step-by-step explanation:

The equation of a circle is given by

(x-h) ^2 + (y-k)^2 = r^2  where (h,k) is the  center and r is the radius

(x-4) ^2 + (y--1)^2 = 9^2

(x-4) ^2 + (y+1)^2 = 81

The F ratio increases as _________. Group of answer choices the variability between means increases relative to the variability
Alex Ar [27]

Answer:

The F-Ratio increases as, the variability between means increases relative to the variability within groups

Step-by-step explanation:

The F-Ratio is given as follows;

F-Ratio = \dfrac{MS_{between}}{MS_{within}}

Where;

Answer:

$20.44

Step-by-step explanation:

first solve for the whole thing

10 x 6 = 60

now to the red part

2 x 1.5 = 3

now the blue

r^2 * pi = a

2^2 * 3.14

4 * 3.14 = 12.56

now add red and blue

3 + 12.56 = 15.56

now subtract that sum from the whole

60 - 15.56 = 44.44

now do

44.44 / 10 = 4.444

now see how much it would cost for the grass

4.444 * 4.60 = 20.4424 ≈ 20.44

it would cost $20.44 to get the grass reseeded
