The type of sampling used in this scenario is "simple random sampling." In other words, the type of sampling used in this scenario is simple random sampling because each contestant's name has an equal chance of being selected from the bag.
Simple random sampling is a method where each member of the population has an equal chance of being selected. In this case, all the contestant names are written on separate cards, and three names are picked from the bag. Since each card has an equal probability of being selected, this represents simple random sampling.
Other types of sampling, such as stratified sampling or cluster sampling, involve dividing the population into groups or clusters and selecting samples from those groups. However, since the scenario doesn't mention any specific grouping or clustering of the contestants, simple random sampling is the most appropriate classification.
Therefore, the type of sampling used in this scenario is simple random sampling because each contestant's name has an equal chance of being selected from the bag.

Answer:
(C)68
Step-by-step explanation:
Given: From the given figure, it is given that arcDC=112° and arcAB=72°.
To find: the measure of DE.
Solution: From the given figure, it is given that arcDC=112° and arcAB=72°.
Now, it is given that ∠DOC=112° and ∠EOC=180° (straight line)
thus, using the property that the sum of angles around a point is 360°, therefore
∠EOD+∠DOC+∠EOC=360°
⇒∠EOD+112°+180°=360°
⇒∠EOD=68°
Thus, the measure of DE is 68.
Hence, option (C) is correct.
B. 86.40 sq ft
C. 6.94 sq ft
D. 82.52 sq ft
Answer: A. 4.17 sq ft
Step-by-step explanation:
The total surface area of cube is given by :_
Given: The side of cube = 10 in.
We know that 1 feet = 12 inch
∴
Therefore, the side of cube =
Then the total surface area of cube is given by :_
