<span>Actually, yes there is. Being in the 80th percentile means that you are smart than 80% of the people (i.e. out of 100 people, you would be smarter than 80 of them). However being in the top 80% means that you are a part of the 80 smartest people out that same 100. </span>
4c2 + 7c – 5 = 0 a=4 b=7 c=-5
x = [-b +-sq root (b^2 -4ac)] / 2a
x = [-7 +-sq root(7^2 -4*4*-5)] / 2*4
x = [-7 +-sq root(49 + 80)] / 8
x = [-7 +-5.5677643628] /8
x1 = 0.544727125
x2 = -2.294727125
The value of p = 11
y = 5x + p
1 = 5(-2) + p
1 = -10 + p
11 = p
How what size is the large block?
Convert the measurements of the large block to cm.
Then calculate the Volume of the large cube.
The answer will be in cubic cm. That is the number of 1 cm cubes.
