We have to calculate the radius
Radius: Distance between the points (8,2) and (3,7)
Given two points (x₁,y₁) and (x₂,y₂) the distance between these points will be:
Distance=√((x₂-x₁)²+(y₂-y₁)²)
In this case:
Distance=radius=√((3-8)²+(7-2)²)=√(25+25)=√50
Area of a circle=πr²
Data:
r=√50
Therefore:
Area of this circle=π((√50) u)²=50π u²≈157.1 u².
Answer: the area would be: 50π u² or 157.08 u²
Answer:
Number of families in the sample is 218 families
Step-by-step explanation:
Given:
There are 24 families in the sample that turned on television for 21hours or less.
The 11th percentile of the data is 21hours .
The mean of the data is 36hours.
The standard deviation is 32.2hours.
To calculate number of families in the sample = 24 / 0.11 = 218 families
-7.08 = -(7 + 0.08) = -(7 8/100) = -7 2/25
