Answer:
22.5 pages per week
Step-by-step explanation:
Considering that After 2 weeks, he has read
45 pages, and after 6 weeks, he has
read 135 pages
Difference in weeks = 6-2=4 weeks
Difference in pages=135-45=90
Rate per week will be 90÷4=22½ pages per week
To prove this
If 1 week is 22½
2 weeks will be 2*22½=45
6 weeks will be 6*22½=135
Therefore, the reading rate is 22.5 or 22½ pages per week
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.

Step-by-step explanation:
Given the statement
If 
, then E and F are mutually exclusive events.
If two events are mutually exclusive, they have no elements in common. Thus, P(E∩F)=0.
Therefore, the statement is always true as P(E∩F)=0
For mutually exclusive events:
