Answer:
Gets smaller
Step-by-step explanation:
- The standard deviation is the quantification of spread of data. According to descriptive statistics the standard deviation s is given by:
s = Σ ( x - u ) / sqrt ( n )
Where, n : sample size
u : Mean value
- So we see that standard deviation (s) is inversely proportional to square root of sample size (n).
- We can see that as sample size (n) increases the standard deviation (s) decreases.

Compound inequality combines multiple single inequalities.
The solution and interpretation of the inequality is:
<em />
<em> and </em>
<em>. Ryan needs to consume more than 50 grams of carbohydrates, but less than 150 grams of carbohydrates.</em>
<em />
We have:
and 
Solve for x in both inequalities
Divide both sides by 2
Rewrite as:
Also, we have:
Divide by 2
So, the solutions to the inequalities are:
and
This means that Ryan needs to consume more than 50 but less than 150 grams of carbohydrates.
Hence, (a) is correct

Answer:
12 unit squared....................
Answer:
The difference in elevation is 7,716 ft
Step-by-step explanation:
Let
y -----> the elevation of Mt Owens
x -----> the elevation of the bolo cavern
we know that
To find the difference in elevation between the bolo cavern and Mt Owens, subtract the elevation of the bolo cavern from the elevation of Mt Owens
we have
y=7,295 ft ----> is positive because is above sea level
x=-421 ft ----> is negative because is below sea level
therefore
y-x=7,295-(-421)=7,295+421=7,716 ft
