See below for the steps to the two-way relative frequency table
<h3>How to create the two-way relative frequency table?</h3>
The table of values is given as:
Communication Gender Male Female Total
Text 150.0 82.0 232.0
Talk 72.0 36.0 108.0
Social Media Apps 28.0 32.0 60.0
Total 250.0 150.0 400.0
Start by dividing each cell by the column total
Male Female Total
Text 150.0/250 = 0.6 82.0/150 = 0.55 232/400 = 0.58
Talk 72.0/250 = 0.288 36.0/150 = 0.24 108/400 = 0.27
Social Media Apps 28.0/250 = 0.112 32.0/150 = 0.21 60/400 = 0.15
Rewrite properly as:
Male Female Total
Text 0.60 0.55 0.58
Talk 0.288 0.24 0.27
Social Media Apps 0.112 0.21 0.15
Total 1 1 1
The above represents the two-way relative frequency table

Answer:
0.053
Or
1 23/25
Step-by-step explanation:
Hope this helps! :D
B=brianne present age
c=camila present age
b=3c (brianne is three times as old as camila)
b+4=2(c+4) (four years from now she will be two times as old as Camila)
<span>b + 4 = 2c + 8
b = 2c + 8 - 4
b = 2c + 4
Replace b with 3c
3c = 2c + 4
3c - 2c = 4
c = 4
Camila is four years old.
b+4=2c+8
b=2(4)+4
b=8+4
b=12
Brianne is 12 years old. </span>
