A number cube is rolled 120 times. The number 4 comes up 47 times.
We have to determine the experimental probability of rolling a 4.
The formula to evaluate probability of an event is given by:
Probability =
So, Probability of rolling a 4 =
=
Now, we have to find the theoretical probability of rolling a 4.
Total number of outcomes of number cube = {1,2,3,4,5,6}
Probability of rolling a 4 =
So, Option B is the correct answer.
Answer:
4 mins 31 seconds
Step-by-step explanation:
Maximum speed is 203 mph equivalent to
Time taken to attain maximum speed, where v is velocity and a is acceleration hence
The distance traveled when at top speed
Total distance is provided as 12.42 miles converted to ft is 12.42*5280=65577.6 ft
Total distance-distance moved to attain maximum speed will be
65577.6 ft-15127.2 ft=50450.44 ft
Time taken during maximum speed
Total time=101.6155 s+169.45 s=271.06 s
271.06/60=4 mins 31 seconds
