Question

You ask 70 of your classmates if they have any siblings. complete the two-way frequency table to show the results of the survey.

hintHint:

  • Categories are labelled in the left column and top row.
  • The counts are placed in the centre of the table.
  • Totals appear at the end of each row and column.
  • A sum of all counts (a grand total) is placed at the bottom right.

The correct answer is: 45,25,70


    • Two-way frequency chart: 


    Boys

    Girls

    Total

    Yes

    a

    25

    45

    No

    15

    b

    c

    Total

    d

    35

    70


    • Step 1:

    Find a.

    As, we know,

    Totals appear at the end of each row and column

    thereforea + 25 = 45

    a = 45 – 25

    a = 20

    • Step 2:

    Find b.

    As, we know,

    Totals appear at the end of each row and column

    therefore25 + b = 35

    b = 35 - 25

    b = 10

    • Step 3:

    Find c.

    As, we know,

    Totals appear at the end of each row and column

    therefore15 + b = c

    15 + 10 = c

    c = 25

    • Step 4:

    Find d

    As, we know,

    Totals appear at the end of each row and column

    therefored + 35 = 70

    d = 70 - 35

    d = 35

    • Final Answer:


    Boys

    Girls

    Total

    Yes

    20

    45

    No

    Absolute value of a variable has many uses in mathematics. Geometrically, the absolute value of a number may be considered as its distance from zero regardless of its direction. The symbol |.| is pronounced as ‘modulus’. We read |x| as ‘modulus of x’ or ‘mod x’.
