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.
It is becoming a smaller place value such as 2,000->200-> 20-> 2
Answer:
Step-by-step explanation:
La manera correcta de representar este tipo específico de funciones, se deben usar líneas rectas las cuales pasen por lo que se denomina el origen.
Surface Area of the top and bottom =
2•8•3 = 48 in²
Surface Area of the lateral side rectangle =
(8+8+3+3) • 5 = 110 in²
Total Surface Area = 48+110 = 158 in²
Answer: 158 in²
