Answer: 10 minutes
Step-by-step explanation:
1. Jonathan can type 20 documents in 40 minutes (20/40=1/2 per minute), Susan can type it in 30 minutes (20/30=2/3 per minute) and Jack can type it in 24 minutes (20/24=5/6 per minute), then you must add them to obtain the number of pages they wan write in 1 minute working together:
2. Then, the time will it take them type the same document of 20 pages is:
25.592
25.593 (If you need to round because the 4th decimal spot number is larger than 5)
Hope this helps! :)
Under 45 mins is roughly 16%. This is because 68% of the curve exists within 1 SD of the mean. So 16% must be outside and smaller and 16% outside and larger (on average).
It is impossible to determine how likely you are to find someone with exactly the second amount. However, if you are looking for that or less, you would get 84%
