Set up a proportion: 25/100 = 50/n where n = # of teens surveyed
Simplify fraction: 1/4 = 50/n
Cross multiply: n = 200
So 200 teens were surveyed.
Answer:
CASI
Step-by-step explanation:
In Statistics, sampling can be defined as a process used to collect or select data (objects, observations, or individuals) from a larger statistical population using specific procedures.
Sample survey questions are usually read from a computer screen. In a computer-aided personal interview (CAPI), the interviewer reads the questions and enters the responses. In a computer-aided self interview (CASI), the interviewer stands aside and the respondent reads the questions and enters responses. One method almost always shows a higher percent of subjects admitting use of illegal drugs.
This is because they get to interact with a computer rather than a human interviewer.

The key problem is working out the value of 90,000 divide by 10. This is a division operation.
Option-1
Both numbers are divided by 10.
The result is
Option-2
Division operations can be written as fractions, like this.
The numerator and denominator are both divided by 10, or 'cross out a zero from both'.
The result is
- - - - - - -
If x is divided by y equals z, then x is equal to y multiplied by z.
Let's prove it!
This is proven.
