The answer is 0.12 and I did it using long division...
The mean is 61.
Mean basically means "average." First you add up all terms, then you divide that sum by the number of terms you added together. 336 is the total when all numbers are added together and 6 is the number of terms that we had to add.
31 + 55 + 68 + 70 + 70 + 72 = 366
366/6 = 61
A = 3. Hope this helps! (Was trying to show the work but I can't take pictures at the moment.)
Answer: then the triangles would be congruent by ASA .
then the triangles would be congruent by AAS .
Step-by-step explanation:
Given: Two triangles in which
The additional information for proving triangles are congruent can be the then the triangles would be congruent by ASA (two angles and an included side).
then the triangles would be congruent by AAS (two angles and an non-included side).
All the other options are not correct because there is no definition or postulate for congruence which satisfy them to prove triangles are congruent.
Answers:
- Year 2000: 57.7 millions
- Year 2008: 58.4 millions
- Year 2015: 59.0 millions
- Year 2020: 59.4 millions
Explanation:
The given model provides a function that allows to approximate the population of Italy from 1990 through 2008 and predict the populations for other years, assuming validity of the same model over the coming years.
You only need to convert the year into the variable t and subsitute in the model.
1. Calculate t for every year of your interest:
Year t = year - 1990
1990 1990 - 1990 = 0 (initial value)
2000 2000 - 1990 = 10
2008 2008 - 1990 = 18
2015 2015 - 1990 = 25
2020 2020 - 1990 = 30
2. Calculate the population as per the model:
