The mean of the sample is 15.4 and the standard deviation of the sample is 2.87. This shows that the population parameters of the sample is lower and is less dispersed.
3x4=5x-10
12=5x-10
22=5x
x=4.4
3x+4y=12
4y = - 3x + 12
y = -3/4 x + 3; This line has slope equal - 3/4
Perpendicular lines, slope is opposite and reciprocal so slope of new line = 4/3
Passing point (6 , -2)
y + 2 = 4/3(x - 6)
y + 2 = 4/3 x - 8
y = 4/3 x - 10
Answer
Equation: y = 4/3 x - 10
=
