Last november there were 620 comma 666 scheduled passenger flights in a certain country, and in november of 1996 there were 651 comma 829. use a percentage to express the relative change. use the second given value as the reference value. also, write a statement describing the result. the relative difference between november of 1996 and last november is what percent

Absolute change refers to the simple difference in the indicator over two periods in time, i.e.

Relative change refers to the absolute change as a percentage of the value of the indicator in the earlier period, i.e.

Now,

Value in Period 1 = 651,829

Value in Period 2 = 620,666.

Then

The ratio between the difference in amounts of passengers to the amount of passengers in November of 1996 is 4.78%.

3. parallelogram

step-by-step explanation:

we turn each of our sides into direction vectors

ab=b-a=(3 - 7, 1 - 0) = (-4, 1)

bc=c-b=(1,6)

cd=d-c=(4,-1)

da=a-d=(-1,-6)

we see how the opposite sides have negated direction vectors; this is characteristic of a parallelogram.   we have congruent sides ab=cd and bc=da with unequal lengths because 1^2+6^2 is different from (-4)^2+1^2.   so it's not a square or a rhombus.  

we check the dot product of direction vectors of adjacent sides.   we have

ab dot bc = -4(1) + 1(6) = 2

that's not zero so the sides are not perpendicular.   we've ruled out rectangle.

the direction vectors indicate two pairs of congruent parallel sides, so we choose parallelogram over trapezoid.
