Answer: B
Step-by-step explanation:
negative correlation so as x increases y decreases,
as population rises houses should rise, not A
as buildings rise, need more space and less trees, B is the answer
as cars rise population should rise, not C
no correlation, not D
Answer:
2,294.66 square inches
The area of an octagon is given by the formula:
A = 2 * a² * ( 1 + √2 )
So, if we input the numbers we have:
A = 2 * 21.8² * ( 1 + √2 )
A = 2 * 475.24 * (2.4142)
A = 2,294.66 square inches
As you can see, if you double the side of an octagon, its area will quadruples, which is logic since the one variable in the calculation of the area is the side's length... that is squared. So, if you double it, that double factor is squared.
It's as if we had written
A = 2 * (10.9 * 2)² * ( 1 + √2 )
A = 2 * (10.9² * 2²) * ( 1 + √2 )
