Find the length of KU

KU = 8

Step-by-step explanation:

From the diagram

KU + UN = KN , that is

KU + 40 = 48 ( subtract 40 from both sides )

KU = 8

KU = 8

Step-by-step explanation:

UN = 40

        KN = 48

KU + UN = 48

 KU + 40 = 48  {Subtract 40 from both sides}

         KU = 48 -40

         KU = 8

answer:   35 % is the probability of a late departure or an early arrival.

step-by-step explanation:

let l represents the late departure and e represents the early departure.

then, according to the question,

p(l) = 12 %,   p(e) = 27 % and = 4 %

and, we have to find out,

but, we know that,

which is the required equation that will use to find the probability of a late departure or an early departure.

therefore,   the probability of a late departure or an early arrival =   35 %
