Answer:

a. a selection of members from a population in such a way that every possible sample of the same size has an equal chance of being chosen.

Step-by-step explanation:

In the process of simple random sampling, a subset of the population is directly randomly chosen from the whole population, without dividing the population in groups (like in cluster sampling), without taking proximity into account (like in convenience sampling) or using set intervals (like in stratified sampling). In simple random sampling, every possible subset of the same size has the same probability of being selected.

Therefore, the statement that better fits this description is alternative a.

If 3x - 2 = 13, what is the value of x?<br>0-5<br>• 5<br>0 -3.7<br>0 3.7<br>​
SIZIF [17.4K]
X=5 because you add 2 to both side and get 3x=15, and then you divide both sides by 3 to get x alone, and get 15/3 which equals 5

Given:
Cylinder: radius = 8 yd; height = 4 yd
Surface Area = 2 π r h + 2 π r²
SA = 2 * 3.14 * 8 yd * 4yd + 2 * 3.14 * (8yd)²
SA = 200.96 yd² + 401.92 yd²
SA = 602.88 yd²
Volume = π r² h
V = 3.14 * (8yd)² * 4yd
V = 803.84 yd³

Dimension is cut in half. radius = 4yds ; height = 2yds
S.A = 2 * 3.14 * 4yd * 2yd + 2 * 3.14 * (4yd)²
S.A = 50.24 yd² + 100.48 yd²
SA = 150.72 yd²
V = 3.14 * (4yd)² * 2yd
V = 100.48 yd³

SA =
602.88 yd² - 150.72yd² = 452.16 yd²
V =
803.84 yd³ - 100.48 yd³ = 703.36 yd³
