Answer:20%
Step-by-step explanation
When you multiply 64x100, you'd get 6400. Then you divide that by 80, you get 80. And when you have 80/100, you have 20 left out of the 100. So it is 20%.
We want to recast the equation into the standard form equation for a circle centered at (h, k) with radius r. That equation is
... (x -h)² + (y -k)² = r²
Start by completing the square for both x-terms and y-terms.
... x² - 4x + y² + 4y = k
To do that, add the squares of half the coefficients of the x- and y-terms.
... x² - 4x + (-2)² + y² + 4y + 2² = k + (-2)² + 2²
... (x -2)² + (y +2)² = k + 8 = r² . . . . . this is now equal to the square of the radius, so we have
... k + 8 = 6² = 36
Subtracting 8 gives
... k = 28 . . . . . . . matches selection D)
Use a ruler. I can't see the picture.

Answer:
Step-by-step explanation:
Given the data:
Weight ____Height
110 _______ 120
130 _______140
150 _______160
From the data given, we can conclude that that there exist a positive relationship between weight and height. As weight increases, the height increases and vice versa. The weight variable and height variable are positively correlated and thus an individual with a high weight value will have a high height value.
