Answer:C. Ordinal
The data should not used to calculate the average.
Step-by-step explanation: Ordinal level of measurement is the second level of measurement that is concerned with ordering, ranking and classification of data,it does not show the rate or degree of variation between a set of data.
Stanley Smith Stevens is the one who classified data into four levels of measurement,he is a psychologist and a statistician, the data collected should not be used to calculate the AVERAGE of a set of numbers.
3/(x-2)
The answer is x^2+1+3/(x-2)
To get an expression relating to x you need to have x alone on one side of your equation. ie x =
<span>Try this: </span>
<span>rx - st = r </span>
<span>remove st from the rx side </span>
<span>rx = r + st </span>
<span>now divide by r </span>
<span>x = (r + st)/r </span>
<span>You now have your expression relating to x</span>
2 (3µ) t = Mx
M = 6 µt / x
M = 6 * 2.42 * 131 x 10^-9 /
633 x 10^-9
M = 3

By definition, the pitch of a roof is its vertical rise divided (In this case is 7 feet) by its horizontal measurement, which is called "Run" (42 feet). Therefore, you can calculate the pitch of this roof (P) by applying the following steps:
P=Tan^-1(Rise/Run) Rise=7 feet
Run=42 feet
When you substitute these values into the formula P=Tan^-1(Rise/Run), you obtain:
P=Tan^-1(Rise/Run)
P=Tan^-1(7/42) P=9.46º
<span>What is the pitch of the roof?
</span>
The answer is: The pitch of the roof is 9.46º.
