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.

Idk if u got the answer or not, but It's the last graph. Just by looking at it you can point two things out.
1. The y intercept is -3 (so the graph needs to have the point (0,-3) that takes out two options.)
2. The slope is negative. (Which means the graph is going to decrease. So that takes out the other two options that have it increased.)
<u>Answer:</u>
Total number of result at two polling location in a page election is represented by expression 8r + 11.
<u>Solution:</u>
Given that a page election result can hold r result.
Number of result at one polling location = 5r + 15
Number of result at second polling location = 3r - 4
Need to write simplified expression for total number of results at two polling location.
<em>Total number of results at two polling location</em> = Number of result at one polling location + Number of result at second polling location
=> Total number of results at two polling location = (5r + 15) + (3r - 4) = 8r + 11
Hence total number of result at two polling location is represented by expression 8r + 11.
First, pass all the rate of inflation to ballons/hour
John: 1 b/15s * 3600 s/h = 240 b/h
Jamie: 1 b/20s * 3600 s/h = 180 b/h
Jake: 180 b/h
Then sum the rates to obtain the total rate
Total ballons per hour: 240 b/h + 180 b/h + 180b/h = 600 b/h
If it passes x hours the number of ballons inflated is 600*x
The number of ballon defective are 600*x/80
The number of ballons effectiveley inflated = 600x -600x/80 = 600x - 7.5x = 592.5x.
