9-5x=2(x+6)
Step-by-step explanation:
9-5x=2(x+6)
False because descriptive statistics doesn't make any prediction, but inferential statistics make predictions about a population based on a sample of data taken from the population.
Descriptive statistics are informational coefficients that summarize a given data set, but they can't make predictions about the population based on a sample of data for the example is chart or graph.
It has differences from Inferential statistics which allow you to test a hypothesis or prediction from the data. The prediction is made by collecting the sample of data which is taken from the population such as calculating the z-score or ANOVA test.

Answer:
39 units²
Step-by-step explanation:
A line segment from R to V will divide the figure into a 5 by 6 rectangle and a triangle with base 6 and height 3. Appropriate area formulas will help you find the areas of these parts. The total area is the area of the parts.
rectangle area = L·W = 5·6 = 30 . . . units²
triangle area = 1/2·b·h = 1/2·6·3 = 9 . . . units²
Then the polygon area is ...
polygon area = rectangle area + triangle area = (30 +9) units² = 39 units²
