Given:
Total distance = miles
Hiking before lunch = miles
To find:
How much further does Sylvia have left to hike?
Solution:
Let x be the remaining hiking distance.
We know that,
Total hiking distance = Hiking before lunch + Remaining hiking distance
Isolate variable term.
It can be written as
So, miles left to hike.
Therefore, the correct option is C.
Using margin of error, it is found that increasing the sample size results in a smaller sampling error.
The equation for the <em>margin of error</em> is given by:
In which:
From the equation, it can be noted that the margin of error is inversely proportional to the square root of the sample size, hence, increasing the sample size results in a smaller sampling error.
