Answer:
0.21 square meter
Step-by-step explanation:
Area of the section of wall = 1 square meter
Dimension of part of mural completed =
meter by
meter
Part of the mural completed = Area of the rectangular part of mural completed
But,
Area of a rectangle = length x width
So that,
Part of the mural completed = length x width
=
x 
= 
= 0.2083
Part of the mural completed = 0.21 square meter

the last one
Step-by-step explanation:
Answer:
0.025
Step-by-step explanation:
Given that the arrival time of a professor to her office is uniformly distributed in the interval between 8 and 9 A.M.
If the professor did not arrive till 8.20 he will arrive between 8.21 and 8.40
Hence probability for arriving after 8.20 is 1/40
Prob he arrives at exactly 8.21 is 1/60
To find the probability that professor will arrive in the next minute given that she has not arrived by 8: 20.
= Prob that the professor arrives at 8.21/Prob he has not arrived by 8.20
This is conditional probability and hence
= 
It took 12 days for all the 60 gallons of water to leak out of the barrel. If you divide 60 by 5 you will get 12.
