Step-by-step explanation:

a)

Number of children under 5    Number of household   Relative frequency

      0                                                      17                           17 / 50 = 0.34

       1                                                      14                           14 / 50 = 0.28

       2                                                      14                           14 / 50 = 0.28

       3                                                       3                            3 / 50 = 0.06

       4                                                        2                            2 / 50 = 0.04

                                                                50

Note,

Relative frequency  = Class frequency / Total Frequency

b) Percentage of households has two children under the age of 5 ,

= x 100

= 0.28 x 100

= 28%

from the figure we get,

the x axis shows   the months and,

the y-axis shows the number of satisfied customer.

each line or each cell in upward direction (y-axis) shows 500.

the appropriate scale for the y - axis is: -

a = 2000 customers

b = 4000 customers

c = 6000 customers

d = 8000 customers

e = 10000 customers

f = 12000 customers

g = 14000 customers

( - 4 , -7 )

all the lines must parallel  

step-by-step explanation:

coordinates of c = ( - 1 , 2 )

3 units left = ( -4 , 2 )

9 units down = ( - 4 , 11 )
