Area of the rectangular mat = 12 x 4 = 48 in²
Area of the 3 circles = 3( πr²) = 3(3.14 x 2²) = 37.68 in²
P(landing in a circle) = 37.68/48 = 157/200 = 0.79 (nearest hundredth)
Answer: The probability of landing in one of the circles is 0.79.

The area of the circle is approximately 50
<h3>Areas</h3>
The area of a shape is the amount of space occupied by the shape
<h3>Area of circle</h3>
Given the three radius of the circle, the area of the triangle is calculated using:
From the figure, we have:
--- the radius
So, we have:
Approximate
Hence, the area of the circle is approximately 50

Answer:
The correct option is C) r=-0.80
Step-by-step explanation:
Consider the provided information.
Properties of r in a scatter plot:
The value of r is between -1 and +1.
If the value of r is positive then it associated with positive relationship if the value of r is negative it associated with negative value.
The greater value of r would be closely around a straight line(Regardless of sign).
Now consider the provided relation.
The use of regression line is to minimize the distance between projections and real values.
Correlation is inversely proportional to difference between predicted values and actual values.
So for good fit we just need to look for the highest value of r regardless of the sign.
From the provided options the highest value of r=-0.80
Thus, the correct option is C) r=-0.80
