(a) Explanation Given Information: The provided matrices are, Age 0 − 10 10 − 30 over 30 ¯ A = Well Sick Carrier [ 0.70 0.70 0.60 0.10 0.20 0.30 0.20 0.10 0.10 ] and Male Female B = [ 60 , 000 65,000 100 , 000 110,000 200 , 000 230,000 ] 0 − 10 10 − 30 over 30 Age The matrix A represents the proportion of people in the city who are either sick, well, or a carrier due to the hit of epidemic flu in the city and the matrix B represents the population in the city according to age and sex. Formula used: The product of two matrixes of order m × n and p × q is possible only if the internal dimensions, that is, n and p are equal. The order of the resultant matrix will be m × q which means, it is determined by the external dimensions of the two matrices. Calculation: Consider two matrices, Age 0 − 10 10 − 30 over 30 ¯ A = Well Sick Carrier [ 0.70 0.70 0.60 0.10 0.20 0.30 0.20 0.10 0.10 ] And, Male Female B = [ 60 , 000 65,000 100 , 000 110,000 200 , 000 230,000 ] 0 − 10 10 − 30 over 30 Age The product of the matrices of order 3 × 3 and 3 × 2 is possible as the internal dimensions, n and p are equal, that is n = p = 3 (b) To determine The number of males who are sick in the city. Where, Age 0 − 10 10 − 30 over 30 ¯ A = Well Sick Carrier [ 0.70 0.70 0.60 0.10 0.20 0.30 0.20 0.10 0.10 ] Male Female B = [ 60 , 000 65,000 100 , 000 110,000 200 , 000 230,000 ] 0 − 10 10 − 30 over 30 Age (c) To determine The number of female carriers in the city. Where, Age 0 − 10 10 − 30 over 30 ¯ A = Well Sick Carrier [ 0.70 0.70 0.60 0.10 0.20 0.30 0.20 0.10 0.10 ] Male Female B = [ 60 , 000 65,000 100 , 000 110,000 200 , 000 230,000 ] 0 − 10 10 − 30 over 30 Age
