Systematic sampling is a type of probability sampling method in which sample members from a larger population are selected according to a random starting point but with a fixed, periodic interval. This interval, called the sampling interval, is calculated by dividing the population size by the desired sample size.
Answer:

The equation should look something like this.

Be careful with your use between cubing and multiplying; Cubing is multiplying the number by itself multiple times, while multiplying is like repeated adding, yet much easier.
In this case, if it says triple, I highly recommend multiplying by 3, which is what I did, it only looks different because it is in parentheses.

Answer:
Adjacent - DBC and ABC, EBA and ABC
Vertical - ABC and DBE, CBD and EBA
Step-by-step explanation:
A vertical pair of angles are opposite to each other and intersect by two lines. They make an x shape.
Adjacent angles are angles that have a common vertex and side but do not overlap. They make a v shape with another line in the middle.
Answer: 10 minutes
Step-by-step explanation:
First you have to find out how big the tank is. You will have to you the formula Length x Width x Height. 20 x 18 x 10= 3,600 in. Then you would divide that by 360. 3,600/360= 10. It would have to take 10 minutes to empty the aquarium.
