The formula for a directed line is:
X = K1(X2) + (K2(X1) / K3
Y = K1(Y2) + (K2(Y1) / K3
K1 = numerator = 2
K2 = denominator - numerator = 3-2 = 1
K3 = denominator = 3
X = (2(6) + 1(3)) /3
X = (12+3) / 3
X = 12/3
X = 5
Y = (2(11) + 1(2)) /3
Y = (22 + 2) /3
Y = 24/3
Y = 8
The point is (5,8)
Area = 24*Pi ft²
Area = Pi*r²
Pi*r² = 24*Pi
Canceling out Pi
r² = 24
Take square root of both sides
r = √24
r ≈ 4.899
Circumference = 2*pi*r
≈ 2*pi*4.899
≈ 2*3.141*4.899
≈ 30.78
Circumference ≈ 30.78 units.
Hope this explains it.
The expected number of left-handed people in the sample= 45
<h3>Calculation of total number of left-handed</h3>
The number of people selected at random= 450
The percentage of people that are left-handed =10%
Therefore, the number of people that are left-handed,
= 10/100 * 450
= 4500/100
= 45
