Answer:
Step-by-step explanation:
The third quartile is at 75% of total of number of students.
So percentage score great or equal to this is 25%.
The answer would be C. 8.
I would cross multiple the fractions (3*40) and (15 * x)
That would equal 15x= 120
Divide both sides by 15 and you get 8
Or
You could say: what number times 3 gives me 15? The answer would be 5 and then you would divide 40 by 5 to get 8.
Hope the explanation helps :)

Answer:
Volume_stack = 214 n^3
Step-by-step explanation:
The volume of the stack is the sum of the volume of the two boxes
The rectangular box has a volume of
V_rectbox = long*wide*height
V_rectbox = 6 in * 5in * 5 in = 150 in^3
The volume of the cube is
V_cube = long*wide*height , but since all its sides are equal
V_cube = side^3 = (4 in)^3 = 64 in^3
Volume_stack = V_rectbox + V_cube = 150 in^3 + 64 in^3
Volume_stack = 214 n^3
