Answer:
option A, Estimation gives an approximate answer
Answer:
True, It is a example of inferential statistics.
Step-by-step explanation:
There are two types of statistics which are:
- Inferential Statistics
- Descriptive Statistics
In Inferential Statistics we describe the valuable characteristic of the population using a sample of data.
Here, Since the professor is estimating the average score of 1,500 students using an average score of 20 students. So it is Inferential Statistics.
answer:
A) The angles EA and AG are not congruent.
B) m∠F = 90°
m∠E + m∠F = 180°
90 ° + x = 180° (subtract)
x = 90°
C) Both ∠HEF and ∠AGF are congruent becuase they both have the same angle. Try and measure it using a protractor.
