Using proportions, it is found that there is a 0.54 = 54% probability that a randomly selected household owns a cat.
<h3>What is a proportion?</h3>
A proportion is a fraction of total amount.
In this problem, the proportions associated with owning a cat are given by:
- 70% of 60%(also have a dog).
- 30% of 40%(do not have a dog).
Hence:
p = 0.7(0.6) + 0.3(0.4) = 0.42 + 0.12 = 0.54.
0.54 = 54% probability that a randomly selected household owns a cat.

Answer:
see below
Step-by-step explanation:
1 million
1,000,000 seconds * 1 hour/ 3600 seconds * 1 day/ 24 hours * 1 year / 365 days
.031709792 years
Rounding to 3 decimal places
.032 years
50 years * 365 days/ 1 year * 24 hours/ 1 day * 3600 second / 1 hour
1577000000 seconds
46 inches * 1 ft/ 12 inches * 1 mile/5280 ft
0.000726 miles
A positive one because the nagatives cancel out
