What is the maximum and minimum value of the correlation coefficient? 1 and -1 2 and 3 0 and -1 0 and 1 2 and -2

1 answer:

5 0

Maximum and minimum value of correlation coefficient are 1 and -1 respectively.
When coefficient (r) = 1, it means that every data set values lies on a straight line or you can say that there is perfect positive linear relationship between two variables. When coefficient(r) = -1, it means that every data set values lies on a straight line but this straight line has negative slope. So they are also said to be perfect negative linearly related.

A contractor has been hired to install flooring for a bandstand in the shape of a circle that is 21 feet across. How many square

SOVA2 [1]

Answer:

A. 346.19 square feet.

Step-by-step explanation:

We have been given that a contractor has been hired to install flooring for a bandstand in the shape of a circle that is 21 feet across.

To find the square feet of flooring required, we will find area of circle.

Since the length across the circle is 21 feet, so radius of circle will be half of 21 feet.

$\text{Radius}=\frac{\text{21 feet}}{2}$

$\text{Radius}=\text{10.5 feet}$

$\text{Area of circle}=\pi r^2$

$\text{Area of circle}=\pi (\text{10.5 feet})^2$

$\text{Area of circle}=3.14*110.25\text{ feet}^2$

$\text{Area of circle}=346.185\text{ feet}^2$

$\text{Area of circle}\approx 346.19\text{ feet}^2$

Therefore, 346.19 square feet of flooring will be required.
