Answer:
3y+x = 3
Step-by-step explanation:
for the point ( 3,0)
x=3 , y= 0
the equation for the line is given as
y-y1= m(x-x1)
for perpendicular ,
m= -1/x
so
y-0 = -1/3(x-3)
3y= -x +3
3y+x=3

N = total number of variables = 15.
25th percentile = [(N + 1)/4]th variable = (15 + 1)/4 = 4th variable.
So, the 25th percentile = 4th variable = 202.
80th percentile = 0.8(N + 1) th variable = 0.8 × (15 + 1) = 12.8th variable = 13th variable = 285
