In a recent poll, a random sample of adults in texas was asked whether they supported a proposed tax increase. the complete results of the poll are shown below.

what percentage of the respondents did not support the tax increase?

53.8% of respondents did not support the tax increase

483 + 807 + 210 = 1500. This means there was a total number of 1500 adults that voted on the tax increase. Because there was 807 voters who said no, 807/1500 of the voters did not support it. 807/1500 = .538 * 100 = 53.8%

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
