Which statement describes the function through the points ?

C

Step-by-step explanation:

It's difficult to see the answer options. However, this graph is not a direct variation of the form y=kx. In order to be direct variation, the function must be proportional and run through the origin. If you continue the points to the left, it will not cross at the origin (0,0). But this is a function, so C is the best choice.

why do wages differ across industries

step-by-step explanation :

micro economists are concerned with economics on an industry or individual firm basis.

macro economists are concerned with national and international level

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
