Answer:
years worked: 14
at least 10 years: 73%
Step-by-step explanation:
The mean is found by adding the years of service and dividing by the number of employees. The total years of service is 417, so the average is ...
average years worked = 417/30 = 13.9 ≈ 14 . . . years
__
The percentage of employees that have worked there at least 10 years is found by counting the number with 10 or more years of service and dividing that count by the total number of employees. The result is then expressed as a percentage.
(10 years or over)/(total number) = 22/30 = 0.73_3 (a repeating decimal) ≈ 73%

Comment on the working
A spreadsheet can be helpful for this. It has a function that can calculate the mean for you. Sorting the years of service into order can make it trivially easy to count the number that are 10 or more, or you can write a function that will do the count for you. (Also, less than 10 means the years are a single digit. There are 8 single-digit numbers in your list.) The hard part is copying 30 numbers without error.

the area of the cross-sections, is really the same area as the rectangular faces, so, just use those areas, since they're the same
I hope you want the time taken to finish a 5 km race. Based on this i am solving the problem given.
Amount of time required to jog 2 kilometers = 12 minutes
Then
Amount of time required to jog 1 kilometer = (12/2) minutes
= 6 minutes
So
Amount of time required to jog 5 kilometers = (6 * 5) minutes
= 30 minutes
So it will take 30 minutes to finish a 5 kilometer race.
I hope the procedure is clear to you.
