121 x 12 = 1452 so over 1500 is not a correct estimate. Less than 1500 is the right estimate
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.

Answer:
10m.
Step-by-step explanation:
Add up all the areas of the running path and then you can reach to the answer. I got 10m and most probably it should be that only.
Answer:
the 3rd One!
Step-by-step explanation:
Write 0.055 as
0.055
1
Multiply both the numerator and denominator by 10 for each digit after the decimal point.
0.055
1
The factors of 55 are: 1 5 11 55
The factors of 1000 are: 1 2 4 5 8 10 20 25 40 50 100 125 200 250 500 1000
The Greatest Common Factor (GCF) for both 55 and 1000 is: 5
Now to reduce the fraction we divide both the numerator and denominator by the GCF value.
=
0.055 x 1000
1 x 1000
=
55
1000
In order to reduce the fraction find the Greatest Common Factor (GCF) for 55 and 1000. Keep in mind a factor is just a number that divides into another number without any remainder.
Answer ( 55/1000
= 11/200)
