Answer:
B: A systematic random sample
Step-by-step explanation:
Systematic sampling is a type of probability sampling in which members of a larger population are chosen at random from a larger population but at a fixed, periodic interval. This interval, also known as the sampling interval, is calculated by dividing the population size by the sample size desired. Despite the fact that the sample population is chosen in advance, systematic sampling is still considered random if the periodic interval is set in advance and the starting point is chosen at random.
Hope this helps and if it does, don't be afraid to give my answer a "Thanks" and maybe a Brainliest if it's correct?
Volume (tank)=base x heitht
base is a squeare, so base=side²
Volume(Tank)=side² * height
600 m³=side² * 6 m
side²=600 m³/ 6 m
side²=100 m²
side=√(100 m²)=10 m.
answer: the side of the base is 10 m.
Plug in the values for b =
and h =
A =
Simplify....

Answer:
1000 : 10
Step-by-step explanation:
1 cm = 0.01 m
10 000 cm = 10 000 * 0.01 m = 100m
so the answer is 1000 : 10.
