I think The answer is b. 17
A² + 4a + 3
(a+3)(a+1) This is the length and the width of the rectangle.
Perimeter = length + length + width + width
P = (a+3) + (a+3) + (a+1) + (a+1)
P = a + a + a + a + 3 + 3 + 1 + 1
P = 4a + 6 + 2
P = 4a + 8
B) 4a + 8
Answer:
Descriptive statistic, Inferential statistic
Step-by-step explanation:
Descriptive Statistic:
- The process of summarizing a data to get insight about the data.
- it consist of measure of central tendency and measure of spread.
- It can be about the entire population or a sample of the population.
- It helps to understand the feature of the data
Inferential statistic:
- It is the method of making generalizations about the entire population based on the sample.
- It help us to make prediction about the population parameter with the help of sample statistic.
- This is done with the help of estimation and hypothesis testing.
Thus, the correct answer is:
Descriptive statistics consists of organizing and summarizing information collected, while inferential statistics uses methods that generalize results obtained from a sample to the population and measure the reliability of the results.
