Answer:
B. Ordinal
Step-by-step explanation:
The level of measurement used for a variable in statistical analysis determines what summary statistics and analysis are possible. In statistical analysis, we have three types of level of measurement.
Nominal
, Ordinal , Interval/ Ratio
The nominal is the most basic level of measurement. It is the qualitative level of measurement such as color or number. Data in Nominal scale of measurement are stored as a word or as numerical code.
Ordinal level of measurement are variables based on ranks or hierarchy. Ordinal level of measurement posses a sequential step-wise order but the intervals between the variables are not equal. They are usually expressed in frequencies.
Therefore, the level of measurement of variable that determines the livability rankings for cities based on their ranks or hierarchy is Ordinal.
The interval/ratio level of measurement is the highest level of measurement where data are being measured and ordered in a sequential process.
The three vectors
,
, and
each terminate on the plane. We can get two vectors that lie on the plane itself (or rather, point in the same direction as vectors that do lie on the plane) by taking the vector difference of any two of these. For instance,


Then the cross product of these two results is normal to the plane:

Let
be a point on the plane. Then the vector connecting
to a known point on the plane, say (0, 0, 1), is orthogonal to the normal vector above, so that

which reduces to the equation of the plane,

Let
. Then the volume of the region above
and below the plane is

Answer:
Rent
Step-by-step explanation:
Yes
vertex form of a parabola
y= a(x-h)^2 +k
y =a(x--3)^2 +2
y = a(x+3)^2 +2
