3. We are given that on average 5 passengers will board the bus at each of the 6 stops.
Let x be the number of passengers board the bus at the sixth stop.
Therefore, the average is:




Therefore, 7 passengers need to board the bus at the sixth stop for Leah's prediction to be true.
Let A be the surface area, b the base, h the height;
h₁=8.4 cm
h₂=7.8 cm
b= 9 cm
A= 3(1/2bh₁)+1/2 bh₂
A=3(1/2(9)(8.4))+1/2 (9)(7.8)
A= 148.5 cm³
Plastic sphere volume=4/3 times pi times rasius^3
4/3 times 3.14 times 18^3=24416.6
rubber ball whole=4/3 times 3.14 times 22^3=44579.6
subtract
44579.6-24416.6=20163
the answer is 20163 in^3
