The pulse rates, in beats per minute, for some students of a class are shown below:

82, 88, 67, 88, 85, 67, 79, 76, 79, 67, 88, 67, 85, 79, 67, 88, 79, 88, 76, 67

midge created the following incorrect dot plot to represent the data:

dot plot showing 6 dots over 67, 2 dots over 76, 3 dots over 79, 1 dot over 82, 2 dots over 85, and 5 dots over 88

what should midge do to make the dot plot correct?

put another dot on 79
put another dot on 76
delete one dot on 88
delete one dot on 67

Put another dot on 79

Step-by-step explanation:

Because the plot shows that 79 must have 4 dot.So you need to add one more dot

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
