Answer: median
Step-by-step explanation: Statistical Mathematics
- First, we re-arrange the given data in ascending or descending order.
- Then we count the no. of data (here 8).
- If the data given is odd in count then the middle value of the arranged data is the median.
- but if the case is of even no. of data then we take the average of the two middle values of the arranged data.
7, 10, 16, 21, 26, 30, 40, 43
Here we have an even number of the data entries so we get two values in the mid.
Now take the average of those mid values:
<h2>- Subtract the least value from the greatest value to find the range.
- For midrange add together the greatest value and the least value and divide by 2.
- Mean is the average of all the values.
- Mode is the value that occurs the most number of times.

Answer:
<em>P=760</em>
Step-by-step explanation:
Three of the coordinates of the square ABCD are A(-212,112) B(-212,-3) C(2,112). The image below shows the square is not ABCD but ABDC. In fact, this is not a square, as we'll prove later.
Note the x-coordinate of A and B are the same. It means this side is parallel to the y-axis. Also, the y-coordinate of A and C are the same, meaning this side is parallel to the x-axis. The missing point D should have the same x-coordinate as C and y-coordinate as B, i.e. D=(2,-3).
This shape has sides that are parallel to both axes.
To calculate the perimeter we find the length of two sides.
The distance from A to B is the difference between their y-axis:
w=112-(-3)=115
The distance from A to C is the difference between their x-axis:
l=2-(-212)=215
It's evident this is not a square but a rectangle. The perimeter is
P=2w+2l=330+430
P=760
