Assume the radius is R.
2*pi*R = 28 -> R = 14/pi
So the area will be pi*R^2 = 196/pi
Solution: The formula for mean is:

Where:
is the sum of given observations
is the number of observations


rounded to two decimal places
To find the median, we need to first arrange the data in ascending order but we are already given the data in ascending order.
Therefore, the median is:






Therefore, the median = 1.53
Yuna ran three times as many kilometers so here expression should be 3k and the answer is 36.6
We have given that k = 12. 2
We have to find the expression
<h3>What is the writing and evaluating the expression?</h3>
Expressions are considered to be mathematical statements that have at least of two terms comprised of numbers or variables that should be linked. It could be of addition, subtraction, multiplication, or division.
Write the expression as 3k
Second, substitute 12.2 in for the variable, k.
Third, simplify by multiplying 3 and 12.2.
Therefore the answer is 36.6

Answer:
B
Step-by-step explanation:
Data set D does not contain the value 128, which is the median value.
Data set C does not contain the outlier value 91.
Data set A contains value 168, which does not show up on the plot.
The only remaining choice is B.
_____
In order, the data values of set B are ...
... 91, 114, 120, 126, 128, 128 134, 136, 139, 142, 152
The median value of these 11 is the 6th one: 128. The median values of the remaining two sets of 5 are 120 and 139, making these values the quartiles at the ends of the box. The value 91 is more than 1.5 times the IQR (19) below the 1st quartile, so is considered an outlier. (The cutoff is 120-1.5·19=91.5.)
