B and C are correct.
A circle has 360°. 2/3 of that circle is given by
2/3(360) = 720/3 = 240°.
Stu takes half of this, so his piece will have 240/2 = 120°.
He splits the remainder of it between his 2 sisters; 240-120 = 120° left; 120/2 = 60° for each sister's piece.
Answer:
The answer is 73.
Step-by-step explanation:
To find the total number of points for a win, you would do 3*22 which equals 66.
Then the number of draws, which is 7 draws, has one point per draw, so it would be 7.
Add 66 by 7=73
Hope this helps!

Answer:
-37
Step-by-step explanation:
Simplifying
74 + 2x = 0
Solving
74 + 2x = 0
Move all terms containing x to the left, all other terms to the right.
Add '-74' to each side of the equation.
74 + -74 + 2x = 0 + -74
Combine like terms: 74 + -74 = 0
0 + 2x = 0 + -74
2x = 0 + -74
Combine like terms: 0 + -74 = -74
2x = -74
Divide each side by '2'.
x = -37
Simplifying
x = -37
Std dev = sqrt of variance
hence variance would be 17^2= 289
