Given
49, 34, and 48 students are selected from the Sophomore, Junior, and Senior classes with 496, 348, and 481 students respectively.
To find:
Which of these types of sampling is used: random, stratified, systematic, cluster, convenience?
Explanation:
It is given that,
49, 34, and 48 students are selected from the Sophomore, Junior, and Senior classes with 496, 348, and 481 students respectively.
That implies,
Since Stratified random sampling is a method of sampling that involves dividing a population into smaller groups–called strata.
Then, the random sampling used is Stratified Random Sampling.

Step-by-step explanation:
<u>Step 1: Define</u>
2(x - 4) + 4(45x + 6)
<u>Step 2: Simplify</u>
- Distribute: 2x - 8 + 180x + 24
- Combine like terms (x): 182x - 8 + 24
- Combine like terms (Z): 182x + 16
Answer:
