359 goes to 360
224 goes to 220
360-220=140
I moved the answer up one then down four the way I moved the original numbers, so 140 is actually down three of the actual answer which must be 143 then
The mean is the sum of all 12 numbers divided by 12, which is 578.25 ~ 578.3. The variance is calculated by subtracting each score from the mean, squaring, and adding all such squares. Then divide by the number of terms (12) to get 68572.35. Take the square root to get the standard deviation, which is 261.9. So the correct answer is B.
Greetings!
(There are 3785.41 mL in a gallon.)
There are 60 seconds in minute. Therefore, if we divided the gallon per minute by 60, we can get the answer.
105/60
=1.75 gallon per second
1.75*3785.41
=<span>6624.4675 mL per second
Hope this helps.
