Answer:
1 hour 42 minutes
Step-by-step explanation:
Given: Speed of 1st trucker= 62 mph
Speed of 2nd trucker= 66 mph
Total distance need to cover to be in contact is 270 miles
1st trucker start 1 hour ahead of 2nd trucker
Lets assume 2nd trucker take `x` hours to be in contact and 1st trucker take `(x+1)` hours.
We know, distance=
1st trucker, distance
∴
2nd trucker, distance
∴
Now, putting the values in an equation.
⇒
Opening the parenthesis to solve and subtracting both side by 62
⇒
∴ x= = 1 hour 42 minutes
∴ It will take 1 hour 42 minutes to be able contact each other after first trucker leaves.
Answer:
Step-by-step explanation:
Well, an even decimal die has probability 0.5 of rolling even and 0.5 of rolling odd.
->The chances of rolling exactly one even number on five rolls is
->The chances of rolling exactly three even numbers on five rolls is
The chances of rolling exactly five even numbers on five rolls is
Further, the probability of independent events is the sum of their probabilities, so the probability of rolling an odd number of even numbers is
