The first term of the arithmetic progression exists at 10 and the common difference is 2.
<h3>
How to estimate the common difference of an arithmetic progression?</h3>
let the nth term be named x, and the value of the term y, then there exists a function y = ax + b this formula exists also utilized for straight lines.
We just require a and b. we already got two data points. we can just plug the known x/y pairs into the formula
The 9th and the 12th term of an arithmetic progression exist at 50 and 65 respectively.
9th term = 50
a + 8d = 50 ...............(1)
12th term = 65
a + 11d = 65 ...............(2)
subtract them, (2) - (1), we get
3d = 15
d = 5
If a + 8d = 50 then substitute the value of d = 5, we get
a + 8
5 = 50
a + 40 = 50
a = 50 - 40
a = 10.
Therefore, the first term is 10 and the common difference is 2.

Answer:
Step-by-step explanation:
Given that a study of 250 households in Cedar Bluff showed that a household produced an average of 4 pounds of garbage per day.
Here a study of only 250 were made to assess about the entire households in Cedar Bluff
Hence the population of interest in this study is the entire households in Cedar Bluff.
The sample is the 250 households in Cedar Bluff which were studied
The objective was to study the sample and from that information to assess about the population.
