iragen [17]

Answer:

The expression is  

.\ \ \ \ \ \  \ \ \ \ \ \ \ \ \ \ \ \ B \   \ \ \ \ \ C \ \ \ \ \ T\\M = \left \  NYC} \atop {LA}} \right.  \left[\begin{array}{ccc}{284}&{483}&{410}\\{597}&{551}&{233}{2}}\\\end{array}\right]

Step-by-step explanation:

From the question we are told that

    The  number of each items made in the month of January[J] is  

   .\ \ \ \ \ \  \ \ \ \ \ \ \ \ \ \ \ \ B \  \ \ \ \ C \ \ \ \ \ \ T\\J = \left \  NYC} \atop {LA}} \right.  \left[\begin{array}{ccc}{144}&{474 }&{274}\\{598}&{572}&{302}\\\end{array}\right]

The  number of each items made in the month of February[F] is  

 .\ \ \ \ \ \  \ \ \ \ \ \ \ \ \ \ \ \ B \  \ \ \ \ C \ \ \ \ \ \ T\\J = \left \  NYC} \atop {LA}} \right.  \left[\begin{array}{ccc}{ 424}&{492}&{546}\\{596 }&{530}&{164}\\\end{array}\right]

Generally given that the production for March of all products at all locations was the average of the January and February production then the number of each items made in the month of March[M] is

    .\ \ \ \ \ \  \ \ \ \ \ \ \ \ \ \ \ \ B \  \ \ \ \ \ \ \ \ \ \ \ \ C \ \ \ \ \ \ \ \ \ \ \ T\\M = \left \  NYC} \atop {LA}} \right.  \left[\begin{array}{ccc}{\frac{144 +424}{2}}&{\frac{474 +492}{2}}&{\frac{274 +546}{2}}\\{\frac{598 +596}{2}}&{\frac{572 +530}{2}}&{\frac{302+164}{2}}\\\end{array}\right]

=> .\ \ \ \ \ \  \ \ \ \ \ \ \ \ \ \ \ \ B \   \ \ \ \ \ C \ \ \ \ \ T\\M = \left \  NYC} \atop {LA}} \right.  \left[\begin{array}{ccc}{284}&{483}&{410}\\{597}&{551}&{233}{2}}\\\end{array}\right]
