11) blood type male female a 105 93 b 99 84 o 160 140 ab 15 18 a survey of patients at a hospital classified them by sex and blood type, as shown in the table. what percent of the female patients have type-o blood? [round the answer to the nearest tenth of a percent.] a) 41.8% b) 46.7% c) 47.8% d) 71.8%

The answer is C.

93+84+140+18=335

140/335=0.4179(100)

41.8%

the discriminant is 64 + 4*1*12 = 112

this is prime.

step-by-step explanation:

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
