Using sampling concepts, the population and the sample are given as follows:
d. population: 6,000 batches of 100 cards sample: every 100th batch.
<h3>What is sampling?</h3>
It is a common statistics practice, when we want to study something from a population, we find a sample of this population, which is a <u>group containing elements of a population</u>. A sample has to be representative of the population, that is, it has to involve all segments of the population.
For example:
I want to estimate the proportion of New York state residents who are Buffalo Bills fans. So I ask, lets say, 1000 randomly selected New York state residents whether they are Buffalo Bills fans, and then:
- The population is: All New York State residents.
- The sample is the 1000 randomly selected New York state residents.
Hence, in the situation described the population is the 6,000 batches of 100 cards, while the sample is every 100th batch, hence option d is correct.

They are all quadrilaterals <span />
Answer:
each of them has to pay $11.5 individually
Step-by-step explanation:
The computation of the amount paid by each one is shown below:
As carla and Ana gone for an icecream and the bill is $23 that should be divided equally
So here the carla should pay
= $23 ÷ 2
= 11.5
And, Ana should pay
= $23 ÷ 2
= $11.5
Hence, each of them has to pay $11.5 individually
To solve this, you can use this helpful equation:
= 
Since you now have this equation, you can just plug in.
= 
To find x you would cross multiply, multiply the x with 100 and the 15 with the 20%.
100x = 300
Now to find x you would just divide both sides by 100.
x=3
