It's suppose to add 450mph+250mph=700 then divide 3 hours=233.3
Answer:
i didn't understand what your question is
Number of first class passengers = 325
Number of surviving passengers that took first class = 203
The probability that a passenger survived given that they took taking first class is
number of surviving passengers in first class/number of first class passengers. Thus, the probability is 203/325
Okay this is very simple
The length of the longest lead is 1 3/4
The length of the shortest lead was 1/4
The difference between the longest lead and the shortest lead is 1 1/2
The length the most students had was 1/2
The of the sum of the two shortest lengths are 3/4
The difference of the longest lead and the second shortest lead is 1 1/4
hope this helps :)
6, 3, 8 those are the answer
