Answer:
The statement is false.
Step-by-step explanation:
Let a and b represent two odd integers.
The average (A) is defined by:
A=
In order to prove the statement, you have to show that it's true for all odd integers. But, to disprove it, you just have to find a counterexample where the statement is false.
Notice that it is easier to try to find a counterexample.
For example, a=3 and b=5
A= 
The result of the average is even, therefore the statement is false.
The previous calculation is a counterexample.

Answer:
Step-by-step explanation:
a)
d=0.68t + 1.5 if t time is 3 hrs
d=0.68(3) + 1.5
= 2.04 + 1.5
d= 3.54 ft
b)
d=0.68t + 1.5 if d depth is 4 ft solve for t
d - 1.5 = 0.68t
(d - 1.5) / 0.68 = t
(4 - 1.5) / 0.68 = t
t = 2.5/0.68
t = 3.68 ft
