Answer:
The probability of finding the entry in the period between 30 and 32 minutes is 5%.
Step-by-step explanation:
Given that the time required to find an entry is uniformly distributed between 0 and 60 minutes, it implies that 100% of the chances are in that period of time distributed equally. Therefore, since 100/60 is equal to 1.66, each minute has a 1.66% chance that the entry will be there.
Thus, since between minutes 30 and 32 there are 3 minutes in total (30, 31 and 32), to determine the probabilities of finding the entry in that period it is necessary to perform the following calculation:
1.66 x 3 = X
5 = X
Therefore, the probability of finding the entry in the period between 30 and 32 minutes is 5%.
Mode: ( The number seem the most )
14. 240
15. 3 and 9
16. 60
Range: ( The biggest and smallest number subtracted )
14. 330-210=120
15. 11-3=8
16. 65-57=8
I think it is b .because negative numbers are less than anything
