Step-by-step explanation:

M^2 = M*M

       =  2 5       *       2 5

            1 8                1 8

      = (2*2) + (5*1)      (2*5) + (5*8) ..rows of the 1st matrix * column of 2nd matrix

         (1*2) + (8*1)       (1*5) + (8*8)

There are six households in a rural community. Each household earns $40,000 per year. Suppose that a new resident builds a mansi
dusya [7]

Answer:

Median income has not changed

Mean income has increased

Step-by-step explanation:

Initial number of houses = 6

Earning per household = $40,000

The initial mean :

$(40,000 * 6) / 6 = $40000

Initial median :

40000, 40000, 40000, 40000, 40000, 40000

= 1/2(n+1)th term,

Median = 40000

A 7th household earns 4,000,000

Mean = ((40000*6) + 4,000,000) / 7 = $605,714

Median = 1/2(n+1)th term

40000, 40000, 40000, 40000, 40000, 40000, 4000000

Median = 4th term = 40000
