I would say the answer is A) missing data because they have lost 8 of the original participants in the study.
Ok so I can't sketch a graph for you because I don't know how to but i can give a formula that will help you graph it on your own. The equation is y = 8x having x represent the amount of extra pages you want to add. I came to this equation because if 8 photos can fit in each extra page and x represents the the extra pages then 8 photos is the slope for the equation y = mx + b. So if you were to graph this you will get a continuous line because it has no holes.
It would be zero bc they cancel out each other
6/11 = 0.54_54 . . . . . the digits 54 are repeated indefinitely
You can arrive at the digits 54 by multiplying the numerator (6) by 9. This will be the case for any proper fraction with 11 as a denominator.
