<span>As of January 8, 2015, the U.S. is $18.1 trillion in debt. (Source: National Priorities Project)
1 Trillion
= 1 Thousand Billion
= 1,000,000,000,000
= 10</span>¹²

U.S National debt currently stands at:

*What information would be lost? Well firstly the 0's. The 0's put the size of the number into perspective. The word "trillion" would also be taken out of the picture, once again altering the perspective of the number.
Personally I'd prefer to hear "18.1 Trillion Dollars". Sounds more interesting.

Answer:
The answer is x = -3, 3
Step-by-step explanation:
Answer:
1/3 I think
Step-by-step explanation:
The commutative property is shown. It states that an equation has the same value as it would even if the numbers were mixed. In this equation, the 2 and the 3 are switched within the parentheses, so it still has the same value.
Answer:
The confidence interval at 95 % for which we assume that it contains the true value is (0.0962, 0.1838).
Step-by-step explanation:
We have that to find our 
level, that is the subtraction of 1 by the confidence interval divided by 2. So:
Now, we have to find z in the Ztable as such z has a pvalue of 
.
So it is z with a pvalue of 
, so 
Now, find M as such
In which 
is the standard deviation of the population and n is the size of the sample.
The lower end of the interval is the mean subtracted by M. So it is 0.14 - 0.0438 = 0.0962
The upper end of the interval is the mean added to M. So it is 0.14 + 0.0438 = 0.1838
The confidence interval at 95 % for which we assume that it contains the true value is (0.0962, 0.1838).
