<span>Interval between 2.6 minutes late and 8.2 minutes late is within 2
standard deviations of the mean (k =8.2â’5.4/1.4 =5.4â’2.6/1.4 = 2). By Chebyshev’s Theorem, at least 1 â’1/2^2 =3/4 of all flights, i.e. at least 75% of all flights arrive
anywhere between 2.6 minutes late and 8.2 minutes late.</span>

Multiple each term by 3X
(X-3)/3x (3x)+1 * (3X) = 27 (3X)
Simplify 4X -3= 81 X
Move x to the left side
-77X -3 =0
-77X = 3
X= - 77/3
Demical form : x= 0.038961
