Answer:

3/4 of a liter

Step-by-step explanation:

2 - 5/4

Get a common denominator

2 *4/4 -  5/4

8/4 - 5/4

3/4

The denominator is 4 so rewrite 2 liters as a fraction with 4 as the denominator.

4/4 = 1 so 2 liters would be 8/4

Now subtract:

8/4 - 5/4 = 3/4

There is 3/4 of a liter left.

</span>Pick two pairs
<span><span>4x - 3y + z = - 10</span><span>2x + y + 3z = 0
</span></span>eliminate the same variable from each system
<span><span>4x - 3y + z = - 10</span> 
<span>2x + y + 3z = 0</span> 

<span>4x - 3y + z = - 10</span>

A polling organization announces that the proportion of American voters who favor congressional term limits is 64 percent, with
kvasek [131]

Answer:

We are 95% confident that the proportion of American voters who favor congressional term limits is 64 percent with a difference of 3% for small sample size.

Step-by-step explanation:

95 % confidence means that we are 95 % confident that the the proportion of American voters who favor congressional term limits is 64 percent.

95 % confidence  means that of all the sample about 95 %  values are within in the given range.

And only 5% sample are not included in the given parameter.

Margin of error is the amount of miscalculation or difference in change of circumstances from the obtained data.

3% margin of error usually occurs when the data size is small.

As the data size increases the margin of error decreases.

So this statement tells us that we are 95% confident that the proportion of American voters who favor congressional term limits is 64 percent with a difference of 3% for small sample size.

Margin of error= z *σ/√n→

This indicates that as the sample size decreases the margin of error increases and vice versa.
