True or false? the first distribution shown below has a smaller standard deviation than does the second distribution.1, 2, 3, 4, 5, 6, 7, 8, 9, 10, 11, 12101, 102, 103, 104, 105, 106, 107, 108, 109, 110, 111, 112

False, they have the same standard deviation

Step-by-step explanation:

Standard deviation is the distance each data value is from the mean.

While the mean of each data set will be different, the distance each data value is from this mean will be the same.  This is because each set goes sequentially from 1 to 12, or from 101 to 112.  The average distance from the mean will have to be the same.

To verify, using a graphing calculator, the standard deviation of the first set is 3.45.  The standard deviation of the second set is also 3.45.

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
