This question reveals an intriguing pattern.
The rule or pattern to follow here is:
For the left side of the number compared to its predecessor: (First digit x Third digit + 1)
For the right side: (Second digit x Fourth digit -1)
For instance, consider 6447. Next, let's examine its previous number, 9876.
Now,
and

that's how we arrived at 6447
Next, for the third number, 2527, let's look at its previous number, 6447
Now, 
and 
that's how we reached 2527
Following the same reasoning, the missing number should be 534.
This conclusion came from applying the rule of the pattern as:

and

Thus, we derived 534.
In a semicircle, there exist pi radians, whereas a full circle consists of 2pi radians. Since 2pi equals approximately 2*3.14, it results in roughly 6.28 radians in half a circle. The total of 2pi radians corresponds to 360 degrees.
Response:
D
Step-by-step explanation:
Organizing the data in increasing order to find the outlier and compute the mean
Detailed explanation:
The provided data consists of: [4, 1, 3, 10, 18, 12, 9, 4, 15, 16, 32]
Arranging it in ascending sequence
[1, 3, 4, 4, 9, 10, 12, 15, 16, 18, 32 ]
The outlier is identified as 32
Calculating the mean;
Mean=total of data set/quantity of data set
Total= 1 + 3+ 4+ 4+ 9+ 10+ 12+ 15+ 16+ 18+ 32=124
Quantity of data set=11
Mean=124/11=11.27
