The data set represents the ages of students, in years, attending a robotics club meeting. What is the median age of the students in the club? ​ 13,\ 15,\ 12,\ 12,\ 11,\ 16,\ 11,\ 13,\ 14,\ 1213, 15, 12, 12, 11, 16, 11, 13, 14, 12 ​ ​The median age of the students in the club is years.

12

Step-by-step explanation:

12

-13

step-by-step explanation:

f(x)=2x-5 for f(-4)

f(-4)   means let x=-4

f(-4) = 2(-4) -5

f(-4) =-8-5

      = -13

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
