Answer:
52 ft
Step-by-step explanation:
For each chord, the product of segment lengths is a constant. We can find that constant as the product of the segment lengths of the bisected chord:
(24 ft)·(24 ft) = 576 ft^2
Then the missing segment length (DX) of the diameter chord is ...
DX·(36 ft) = 576 ft^2
DX = (576 ft^2)/(36 ft) = 16 ft
So, the total length of the diameter chord is ...
DX +XL = 16 ft + 36 ft
DL = 52 ft
_____
We know DL is a diameter because the perpendicular bisector of any chord intersects the center of the circle.

FISH does not work because the S is not horizontally symmetric.
BONE doesn't work because the N is not horizontally symmetric.
Let the speed off the walk way be x and speed of the walkway be y
x+y=6....i
x-y=2....ii
adding the above equation we get:
2x=8
thus
x=4 ft/s
and
y=6-4=2 ft/s
thus the speed off the walk way is 4 ft/s
the speed of the moving walkway is 2 ft/s

▹ Answer
<em>(-1, 3)</em>
▹ Step-by-Step Explanation
y - 4x = 7
2y + 4x = 2
<u>Substitute</u>
y - (2 - 2y) = 7
<u>Solve</u>
y = 3
<u>Substitute</u>
4x = 2 - 2 * 3
<u>Solve</u>
x = -1
<u>Final Answer</u>
(x, y) = (-1, 3)

Answer:
A. 0.009899
B. 0.005624
Step-by-step explanation:
Data:
Let the probability that an item is defective = 
The probability that the item is not defective = 
The probability that the fifth item is defective = 
= 0.009899
Probability that one in 5 items is defective = 0.005624
