You can complete three-tenths of a task in an hour. Your friend can complete one-fifth of the same task in an hour. How long will it take to complete the task if you work together? Explain.
hours.

2 hours

Step-by-step explanation:

If you convert 1/5 to tenths it's 2/10.

If you add 2/10 and 3/10 you get 5/10 which would be how much off the task you got done in one hour.

Therefore you times 5/10 by 2 and you get 10/10 so the task is done and it took 2 hours.

dalila is incorrect. the whisker on the left is very long, going all the way out to 5. the whisker goes from 5 to 30, so it has a spread of 25. the rest of the box plot values are closer together, so 5 is an outlier

14.3

step-by-step explanation:

add all the numbers together.

9 + 12 + 15 + 16 + 17 + 17 = 86

now, divide 86 by how many numbers we have: 6.

86 / 6 = 14.3
