Using the uniform distribution, we have that:
a) The density curve is given at the end of this question.
b) 16.67% of the time does a customer have to wait between 100 and 120 seconds.
-----------------
The uniform distribution has two bounds, a and b, and the probability of finding a value between c and d is given by:

- Uniform distribution on the interval of 0 to 120 seconds, thus
.
The proportion between 100 and 120 seconds is:

0.1667*100% = 16.67%
16.67% of the time does a customer have to wait between 100 and 120 seconds.

Answer:
0.341
or 1.0723
Step-by-step explanation:
the volume of hemisphere = (2/3)

r = (1/2)d = 0.8
(2/3)
= 0.341
= 1.0723
The package weighs 30 ounces.
Step-by-step explanation:
Mailbox Plus charges;
Charges per ounce = $0.25
Let,
x be the number of ounces.
M(x)=5+0.25x
United packges charges;
Charges per ounce = $0.35
U(x) = 2+0.35x
Cost will be same when the functions are equal;
M(x) = U(x)

Dividing both sides by 0.10

The package weighs 30 ounces.
