22. Suppose that the teacher started recording on a digital camera with an hour available.
She gives 15 minutes introduction. Thus 60 minutes – 15 minutes is 45 minutes.
She still have 45 minutes remaining, now the question is how many minutes will remain if she uses 1 minutes per students.
Since the number of students is not given. It depends on how many students will be there. For example 25 students thus that’s equals to 25 minutes also. So she has a 20 minutes remaining.,
Answer:
The percentages are 267% and 400% respectively.
Step-by-step explanation:
To find the answers of these, you need to divide the second number by the first. This will give you the percentage.
2/3 ÷ 1/4 = 8/3 = 2.67 = 267%
You can do the same for the second one.
2/3 ÷ 1/6 = 12/3 = 4 = 400%
Answer:
2/45
Step-by-step explanation:
Total socks:
7 + 8 + 10 + 5 = 30
P(blue) × P(patterned)
8/30 × 5/30
4/15 × 1/6
2/45
Answer:
Step-by-step explanation:
a) No of outcomes= 7
total no of outcomes= 10
probability = no of outcomes/total no of outcomes
=7/10
b) 4/10 ( since the outcomes could be 1,2,3,4)
c) no 1 to 10 has 5 odd numbers
so, probability = 5/10 = 1/2
d) multiples of 3 from 1 to 10 are :-
3,6,9= 3 no's
so probability = 3/10
