(x4 - 4x3 + 2x2 - 4x + 1) / (x2 + 1)

7 is the median   7.875 is the mean

step-by-step explanation:

3,4,5,6,8,11,13,13

0

step-by-step explanation:

equals the constant of proportionality.

solve for

for this case we have that by definition, the volume of a cylinder is given by:

where:

r: it's the radio

h: it's the height

we have as data that:

substituting:

so, the cylinder volume is

option d

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
