Yes, it is possible to find mean. The mean of the given boxplot is 32.
Given a boxplot that is shown in the attached images and which represents the distribution of the number of points scored by a cross country team at 12 meets.
We have to find the mean of the given boxplot.
Mean is the average value of a given set of numbers. To find the mean of a data set, add up all the numbers in that set, then divide that total by the number of numbers in the set.
The given numbers are 22,24,26,28,30,32,34,36,38,40,42.
Now, we will calculate the mean of the numbers, we get
mean=Total points scored/ Total number of points
mean=(22+24+26+28+30+32+34+36+38+40+42)/11
mean=352/11
mean=32
Hence, the mean of the given boxplot which is shown in the attached image is possible and it's mean is 32.

Answer:
9.11*10^-4 %
Step-by-step explanation:
To find the probability, you simply need to find the possible outcomes that allows no rooks to be in danger, and the possible amount of ways to place the rooks.
For the first outcome, you start by putting 1 rook in the first columns, you have 8 possible rows to do this. The next rook in the next column will only have 7 possible rows, as you have to exclude the one where the previous rook is located. The next rook, 6 possibilities, the next 5, and so on. So we conclude that the total amount of ways so that none of the rooks can capture any of the other rooks is 8*7*6*5*4*3*2*1 = 8! = 40320
In order to find the total amount of ways to place the rooks, you can just use a combinatoric:
Then:
P =
