#9 . . . #12, and #14:  Excellent.  All correct, and good estimates.

#13:  A very picky comment: 
Your math is correct, but the camera can't take 2/3 of an image. 
That's why the question asked "How many complete images ...".
After 66 images, there is still some time remaining, but not enough
for another image.  So it captures 66 complete images in 3 seconds.


If you are really in elementary school, then I think you're doing
the work of a prodigy.  Keep it up !  And best of luck to you.

Xelga [282]

Answer: 19.2 inches would be the most reasonable answer, since the first two is too small, and the last answer would be too tall.

if there was 2 feet of water, it would be 24 inches full. taking 1 gallon out, wouldn't make the difference to make it go up or down much.

What is the interquartile range (IQR) of the following data set 17 16 21 15 25 22 18 23 17
Pepsi [2]

IQR = 6

First locate the median Q_{2} at the centre of the data arranged in ascending order. Then locate the lower and upper quartiles Q_{1} and Q_{3} located at the centre of the data to the left and right of the median.

Note that if any of the above are not whole values then they are the average of the values either side of the centre.

rearrange data in ascending order

15 16 ↓17 17 18 21 22 ↓23 25

                     ↑

Q_{2} = 18

Q_{1} = \frac{16+17}{2} = 16.5

Q_{3} = \frac{22+23}{2} = 22.5

IQR = Q_{3} - Q_{1} = 22.5 - 16.5 = 6
