Answer:
17.5
Step-by-step explanation:
Because the lines of the trapezoid are parallel that means that side ratios are similar mainly: BC/AB = DE/EF
Which yields: DE = CB * EF/ AB = 18.5 * 8.5 / 9 ~ 17.5
The most appropriate unit of measure to describe the distance around the outside of a small picture frame would be the perimeter.

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.
-20=-4x-6x
First combine like terms.
-20=-10x
Divide by -10 on both sides
X=2
