Step-by-step explanation:
By looking at the graph, there is no clear direction or association that the graph has. Therefore, there is no clear relationship between the variables being compared.

Answer:
c. Include the date on each page of notes
Step-by-step explanation:
The main reason for her not being able to do this is because she did not include the date on each page of notes. Failing to do so means that she does not know which notes she took first and which ones she took later, therefore preventing her from correctly organizing the notes based on when they were taken (in the correct order). Neither the class title or the names of the guest speaker prevent her from organizing her notes in order, thus making the answer c.
The difference between 90% and 72% is 18%
Let the lengths of the bottom of the box be x and y, and let the length of the squares being cu be z, then
V = xyz . . . (1)
2z + x = 16 => x = 16 - 2z . . . (2)
2z + y = 30 => y = 30 - 2z . . . (3)
Putting (2) and (3) into (1) gives:
V = (16 - 2z)(30 - 2z)z = z(480 - 32z - 60z + 4z^2) = z(480 - 92z + 4z^2) = 480z - 92z^2 + 4z^3
For maximum volume, dV/dz = 0
dV/dz = 480 - 184z + 12z^2 = 0
3z^2 - 46z + 120 = 0
z = 3 1/3 inches
Therefore, for maximum volume, a square of length 3 1/3 (3.33) inches should be cut out from each corner of the cardboard.
The maximum volume is 725 25/27 (725.9) cubic inches.
