What is the median of the data set 50 52 68 64 65 61 68 75 75 78

66.5

Step-by-step explanation:

Given data : 50 52 68 64 65 61 68 75 75 78

Step 1 : Arrange the data in an order .

50 52  61 64 65 68  68 75 75 78

Step 2 : Then , calculate the number of elements.

The number of data values in the given data = 10

Since , the data is even then the median of the data will be the mean of the two middlemost values.

Hence, the median of the data set = 66.5

10 * 563.67 = 5636.7

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
