A new condominium unit decided to place its reserve water tank below ground. The engineers excavated the land near the condominium building. Because of the water pipes from the other buildings nearby, the excavated land had the shape of a cone with diameter D, and height H. If the largest possible cylindrical tank will be placed in the excavated land, what is the percentage of the volume of the excavated land that will be occupied by the water tank.
A company that manufactures rivets believes the shear strength (in pounds) is modeled by
N(750,30).
Use the
68–95–99.7
Rule to complete parts a) through c) below.
a) Draw and label the Normal model.
b) Would it be safe to use these rivets in a situation requiring a shear strength of
720
pounds? Explain. Choose the correct answer below.
A.
No, because about 32% of all of this company's rivets have a shear strength of less than
720
pounds.
B.
Yes, because very nearly all of this company's rivets have a shear strength of more than
720
pounds.
C.
No, because about 16% of all of this company's rivets have a shear strength of less than
720
pounds.
D.
Yes, because only about 2.5% of all of this company's rivets have a shear strength of less than
720
pounds.
c) About what percent of these rivets can be expected to fall below
810
pounds?
