Answer:
3/k = x
Step-by-step explanation:
5kx +6 = 7kx
Subtract 5kx from each side
5kx -5kx +6 = 7kx-5kx
6 =2kx
Divide each side by 2k
6 /2k = 2kx/2k
3/k = x
This is the concept of statistics. The correct answer is:
There are twice as many participants in the 0-19 age group than in the 60-79 age group. This is because:
Number of participants in the age group 0-19 is 40 participants
Number of participants in the age group 60-79 is 20 participants.
From the above we see that the age group 0-19 is double the number of age group 60-79 years old.
Therefore our answer is option C
