The following are the last 10 run scores Colin got in cricket: 22, 35, 33, 18, 16, 12, 28, 18, 1, 16 a) Work out Colin's mean score. b) Colin plays cricket again on Sunday. He gets 10 runs. What is his new mean score? Give your answers as decimals

solution:

→c= a b , that is product of a and b is possible only when when a is m × n matrix and b is n × p matrix.

that is, number of columns of a= number of rows of b.

so, size of matrix , c= a b is , if a = (m × n)matrix

b= (n × p)matrix

then a b = [ (m × n)matrix] ×[   (n × p)matrix ]

→→c= a b= [m × p ] matrix

→→size of product a b will be equal to = number of rows of a × number of columns of b

-2 is the right
