What is the residual value when the price of jeans is $28.00?
- 9.37
- 1.13
- 1.13
- 9.37

The sales manager uses
y = 1.75x + 92.13 as a line of best fit.

well the answer is 1.13 because id you divide 28 in to 42 then you will get 1.13

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
