Answer:
B
Step-by-step explanation:
The equation of a circle in standard form is
(x - h)² + (y - k)² = r²
where (h, k) are the coordinates of the centre and r is the radius
To obtain this form use the method of completing the square
Given
x² - 8x + y² - 2y - 8 = 0 ( add 8 to both sides )
x² - 8x + y² - 2y = 8
add ( half the coefficient of the x/y terms )² to both sides
x² + 2(- 4)x + 16 + y² + 2(- 1)y + 1 = 8 + 16 + 1
(x - 4)² + (y - 1)² = 25 → B
If you send me the points I’ll do it in the comments
Answer:
14%
Step-by-step explanation:
First find the total for all the dresses.
Total = 14 + 37 + 22 + 56 + 33
Total = 162
Now you are concerned about the blue dresses.
% = (22 / 162) * 100 = 13.58 %
Rounded to the nearest % it would be 14%
The number of degrees it would occupy in the pie chart would be 360 * 14/100 = 49 degrees.
Answer:
1/9
Step-by-step explanation:
the probability of one blue marble is 1/3 so to find the probability of 2 marbles you multiply it by itself.
