Answer:
3 students
Step-by-step explanation:
If everyone in the class has either a pierced nose or ear, we just simply have to add up the total number of hands raised and minus the number of students in the class.
35+8=43
43-40=3
3 students have both a pierced nose and pierced ear.

Answer: 9/100
Step-by-step explanation:
Probability of people own a cat:
P(cat)=30/100=0.3
Probability of people own a bird:
P(bird)=3/100=0.03
Probability of both own a cat and a bird
P(cat and bird)=(30/100) × (3/100)
=90/1000=9/100=9%
The value of 13 weeks in seconds is 7862400 seconds
<h3>Conversion of weeks to seconds</h3>
In order to convert weeks to seconds, we will use the following conversion factor
1week = 7 days
13weeks = 91days
<u>Convert days to hours</u>
Since 24 hours = 1 day, then;
91 days = (91*24)
91 days = 2184 hours
Convert hours to seconds
1 hour = 3600secs
Hence 2184 hours = (2184*3600)
2184 hours = 78624000 seconds
Hence the value of 13 weeks in seconds is 7862400 seconds
