in a class of 32 students, 75% returned their permission slips for the school field trip how many students did not return their permission slip

8 I believe!

Step-by-step explanation:

75% of 32 is 24 so subtract 24 from 32 which equals 8!

mental cunning

explanation:

he is often referred to as a man of twists and turns

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
