Answer:
2 : 3
Step-by-step explanation:
Let,
Radius of cylinder 1 = R
Radius of cylinder 2 = r
Now,
We know that
Volume of cylinder = πr²h
=> πR²h/πr²h' = 20/27
=> R² × 5/r² × 3 = 20/27
=> R²/r² = 20/27 × 3/5
=> R²/r² = 4/9
=> R/r = √(4/9)
=> R/r = 2/3
=> R : r = 2 : 3

Answer:
89%
Step-by-step explanation:
If he's on time on the previous day, there's a 10% probability he'll be late, which means there's a 90% probability that he'll be on time.
If he's late on the previous day, there's a 20% probability he'll be late, which means there's a 80% probability that he'll be on time.
He's on time on Monday, so there's a 10% probability he'll be late on Tuesday and a 90% probability he'll be on time.
If he's on time on Tuesday, there's a 10% probability he'll be late on Wednesday and a 90% probability he'll be on time.
If he's late on Tuesday, there's a 20% probability he'll be late on Wednesday and a 80% probability he'll be on time.
So the probability he'll be on time on Wednesday is:
0.10 (0.80) + 0.90 (0.90) = 0.89
