Answer:
A population is defined as the data set which consists of all members of a specified group and the sample contains a part or a subset of a population.
For example : all the students of a school are population. But out of all, how many students play sports is a sample.
Hence, the answer is - A population is the complete group under study. A sample is the sub-collection of members of the population from which data are actually collected.
To solve this, follow these steps:
5x + 27 = 9 (x+3) - 4x
Distribute the 9 within the parenthesis:
5x + 27 = 9x + 27 - 4x
Then combine like terms:
5x + 27 = 5x + 27
These two then cancel each other out completely.
This is an identity because an identity in math is when both equations equal each other, which is shown above.
Hope this helps!
Answer: 0.57 hours each day or 34.28 minutes each day.
Step-by-step explanation:
1. You know that:
-Alejandra worked on the animal report for school for 4 hours in a week.
- A week has seven days.
2. Therefore, to calculate the number of hours she worked on the project each day (which you can call 
), you can divide the number of hours worked on in a week by 7 days.
3. Therefore, you obtain the following result:
Multiply the result by 60 to obtain the time in minutes, then:
2340x0.18= 421.20
She paid $421.20 in property taxes
