Answer:
The answer is 14.
Step-by-step explanation:
E= 15
F= 2
The setup would be;
15- 1/2(2)
Multiply 1/2 and 2. Which is 1.
Next you subtract 15-1.
Then there you get 14.
I think you would look at lbs
Step-by-step explanation:
The answer is 70 because each men chops 7 trees so 10 men = 70 trees
So for this, multiply both sides by 9, and your answer will be:

72*10=720 so all the numbers would need to add to 720
the median is 74 so you need to have both 75 and 76 in the set
the mode is 68 so that need to be in at least twice
and the range is 21 so the largest number-21=smallest number
57, 68, 68, 68, 75, 76, 76, 77, 77, 78
