Answer:
a. B
b. 4
c. BD
Step-by-step explanation:
a. Point A is at -7; point D is at +1. The distance between these points is ...
1 -(-7) = 8
The midpoint will be 8/2 = 4 units from either end so will be at ...
A +4 = -7 +4 = -3
or
D -4 = 1 -4 = -3
The point located at -3 is point B, the midpoint of AD.
__
b. Having done the above calculations, we know that segment AB is 4 units long.
__
c. We also know that segment BD is 4 units long. That is because the midpoint divides a segment into two equal parts.

Answer:
Radius = 12 cm
Step-by-step explanation:
Given:
Volume of the cylinder is, 
cm³
Height of the cylinder, 
cm
Let the radius be 
Using the formula for volume of cylinder,
Plug in 3165.12 for 
, 7 for 
and solve for .
Therefore, the radius of the cylinder is nearly 12 cm.
Answer:
There is a 1/64 possibility.
Step-by-step explanation:
Since the probability of selecting student 1's number is 1/8 and then replacing it leaves us with still 8 numbers to choose from, so student 8's probability of being selected is also 1/8. Multiplying these two gives P=1/64, since (1/8)^2 = 1/64.
Hope this helps!
