9 squared is 81
81=9^2
Or, (3^2)^2. Double square!

Answer:</h2>
Four points are always coplanar if:
A. They lie in the same plane.
C. all of them are collinear.
<h2>
Step-by-step explanation:</h2>
<u>Coplanar--</u>
The points are said to be coplanar if all of them lie in the same plane.
<u>Collinear-</u>
The points are said to be collinear if all of them lie on a straight line.
Also as we know that a line always lie in one plane and so all the points that lie on that line will also lie in the same plane.
Hence, we may say that Four points will be coplanar if all of them are collinear.
Hence, the correct options are:
Option: A and Option: C
Answer:
See explanation
Step-by-step explanation:
Solution:-
- The effect of an outlier on the mean, median and range is to be investigated.
- Mean: It is the average of all the values. If the outlier "22" is lies on the upper spectrum of the center value. If the outlier is removed the value of center or mean will decrease.
- Median: The median value is mostly defined as the value around which their is a cluster of data. The value of the outlier "22" if close to that cluster of data points is omitted there will be small deviation in the value of median. If the value of the outlier "22" if far away to that cluster of data points is omitted there will be significant deviation in the value of median.
- Range: Is defined by the uppermost and lowermost value from a set of data points that is considered. The value of outlier will equally effect either of these limits depending where the outlier lies close to upper limit or lower limit of the range.
