Question
The shoe sizes for a varsity field hockey team are:
5.5, 5.5, 6.0, 6.5, 6.5, 7.0, 7.0, 7.5, 7.5, 7.5, 8.0, 8.0, 8.0, 8.5, 8.5, 9.0
Which of the following is the IQR and explains how this measure of variability describes how the values of a dataset vary with a single number?

The IQR is 3.5.This means that the shoe sizes for half of the players are within 3.5 shoe sizes of each other.
The IQR is 3.5.This means that the shoe sizes for half of the players are within 3.5 shoe sizes of each other.
The IQR is 1.5. This means that the shoe sizes for half of the players are within 1.5 shoe sizes of each other.
The IQR is 1.5. This means that the shoe sizes for half of the players are within 1.5 shoe sizes of each other.
The IQR is 1.5. This means that the shoe sizes for the middle half of the players are within 1.5 shoe sizes of each other.
The IQR is 1.5. This means that the shoe sizes for the middle half of the players are within 1.5 shoe sizes of each other.
The IQR is 3.5. This means that the shoe sizes for the middle half of the players are within 3.5 shoe sizes of each other.
The IQR is 3.5. This means that the shoe sizes for the middle half of the players are within 3.5 shoe sizes of each other.

To find the area of a circle, you can use the formula: A = π * r², where A represents the area and r is the radius of the circle.
In this case, you are given that A is 11, and you need to find the radius. Rearranging the formula, we get:
11 = 3.14 * r²
Now, divide both sides of the equation by 3.14:
11 / 3.14 = r²
This gives us the equation:
3.5031847 = r²
To find the radius, we need to take the square root of both sides of the equation:
√(3.5031847) = √(r²)
This simplifies to:
r ≈ 1.87
So, the radius of the circle is approximately 1.87.
To find the area of a circle, you need to use the formula:
A = πr²
Where A represents the area and r represents the radius of the circle. However, in the equation you provided, the variable "г" is used instead of "r". Assuming "г" is meant to represent the radius, we will substitute it into the formula.
A = π(г)²
Since you have the value of π as 3.14, you can now calculate the area by substituting the values:
A = 3.14(г)²
If you have the value of г (radius), you can square it and multiply it by π, which is 3.14.
