Question

A Washerman asks 75 people from two different cities if they own rain boots. Complete thetwo-way frequency table to show the results of the survey.

What pattern do you see in the two-way frequency table?

hint Hint:

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: 32,43,75

Answer:
Given:

Yes

No

Total

City A

a

19

32

City B

28

b

d

Total

c

34

e

Step 1:

Find a.
As, we know,
Totals appear at the end of each row and column
$therefore$ a + 19 = 32
a = 32 – 19
a = 13

Step 2:

Find c.
As, we know,
Totals appear at the end of each row and column
$therefore$ a + 28 = c
c = 28 + 13
c = 41

Step 3:

Find b.
As, we know,
Totals appear at the end of each row and column
$therefore$ b + 19 = 34
b = 34 – 19
b = 15

Step 4:

Find d
As, we know,
Totals appear at the end of each row and column
$therefore$ 28 + b = d
d = 28 + 15
d = 43

Step 5:

Find e.
As, we know,
A sum of all counts (a grand total) is placed at the bottom right
$therefore$ 32 + d = e
e = 32 + 43
e = 75

Final Answer:

Yes

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’.
