Answer:
V=1884 Cubic mm
Step-by-step explanation:
We know that the volume of the Sphere is given by the formula
Where r is the radius and h is the height of the cylinder
We are asked to determine the radius of the hollow cylinder , which will be the difference of the solid cylinder and the cylinder being carved out.
Where
is the the volume of solid cylinder with radius 
and height h
is the volume of the cylinder being carved out with radius 
and height h
where
mm ( Half of the bigger diameter )
mm ( Half of the inner diameter )
mm
Putting these values in the formula for V we get

The answer is y-4x^2 + 12x + 9
Answer:
(-16.494 ; -3.506)
Step-by-step explanation:
student Prob A Prob B difference, d (A-B)
1 20 35____ - 15
2 30 40 ___ - 10
3 15 20 ___ - 5
4 40 50 __ - 10
Difference, d = -15, -10, -5, -10
Xd = Σd/ n = - 40 / 4 = - 10
Standard deviation of d ; Sd = 4.082
The confidence interval for the difference is given as :
Xd ± Tcritical*(Sd/√n)
Tcritical at 95%; df = n - 1 ; 4 - 1 = 3
Tcritical(0.05, 3)). = 3.182
C.I = -10 ± 3.182(4.082/√4)
C.I = -10 ± 6.494462
C. I = (-16.494 ; -3.506)
Answer:
A: (-2, 0)
B: (-1, 0)
C: (-1/4, 0)
D: (1/4, 0)
E: (1/2, 0)
F: (1 1/2, 0)
G: (2, 0)
H: (2 3/4, 0)
I: (3 1/2, 0)
Step-by-step explanation:
<em>From the graph we can see that every 4th line from </em><em>0</em><em> is a </em><em>whole unit</em><em>. </em>
<em>I put a </em><em>0</em><em> in place of the </em><em>y value</em><em> for every coordinate because the points don't move neither up nor down.</em>
