7 hours + 6 hours + 6 hours
=19 hours
12 minutes + 46 minutes + 53 minutes
=111 minutes
=1 hour 51 minutes
19 hours + 1 hour and 51 minutes is 20 hours and 51 minutes. This is the total time.
Average time = total time/number of deliveries
(20 and 51/60) divided by 3
=6.95 hours
= 6 hours and 57 minutes

Answer: 0.0325
Step-by-step explanation:
Binomial probability distribution formula for x successes in n trials:-
, where n is the number of trials , p is the probability of success.
Given : The probability that taxpayers who filed their tax return are electronically self-prepared their taxes : 
If three tax returns submitted electronically are randomly selected, then the probability that all three were self-prepared is given by :-

Answer:
the density of the iron is 7.9 g /cm^3
Step-by-step explanation:
The computation of the density of the iron is shown below:
Density = weight ÷ volume
= 474 ÷ (5 × 3 × 4)
= 474 ÷ 60
= 7.9 g /cm^3
Hence, the density of the iron is 7.9 g /cm^3
Slope = rise/run
The rise is 6
The run is 4
6/4 is the slope or in
decimal form
1.5
