√121 < √134 < √144
√121 = 11
√144 = 12
11 < √134 < 12
Answer: √134 is between 11 and 12.
Answer: 9% parameter, 3% statistic
Step-by-step explanation: Parameter and statistic are are statistical terms used to describe a group or observation.
However, the distinction between a parameter and a statistic is in the measured observation.
Parameter is used to describe an entire population while statistic is used to describe a sample.
Where a population refers to the entire number of people or inhabitant of a particular country while a sample refers to a subset of observation drawn randomly from a population which serves a representative of the entire population.
In the question above, 9% is used to make a description of the whole American population who are at least 75 years of age. While,
3% is used to describe a subset of the American population (sample) who are 75 years or older.
(-a^2 + 1) - (a^2 - 3) + (5a^2 - 6a^2 - 6a + 7)
(-a^2 - a^2 + 5a^2 - 6a^2) - 6a + 1 + 3 + 7
(-2a^2 - a^2) - 6a + 4 + 7
-3a^2 - 6a + 11
Just 2 that is it hope that helps
