Answer:

The volume of the pyramid is 672\ cm^{3}

Step-by-step explanation:

we know that

The volume of the pyramid of the figure is equal to

V=\frac{1}{3}b^{2}h

we have

b=12\ cm

h=14\ cm ----> the height must be perpendicular to the base

substitute

V=\frac{1}{3}(12^{2})(14)=672\ cm^{3}

There are ten numbers so the thirtieth percentile would be the .3 * 10 

= 3rd number, ordered from smallest to largest. 

so the third number, the thirtieth percentile, is 105

Website 1 : y = 1.50x + 30
website 2 : y = 2x + 0...or just y = 2x
=======================
y = 4x - 4
y = -4x + 4

4x - 4 = -4x + 4
4x + 4x = 4 + 4
8x = 8
x = 1

y = 4x - 4
y = 4(1) - 4
y = 4 - 4
y = 0

so this is a consistent system because it has one solution (1,0)
