Answer:
Which formula should be used to calculate the variance? C
What is the variance? 58.5
Using proportions, it is found that the correct amount to administer of CC would be of:
A. 0.5.
<h3>What is a proportion?</h3>
A proportion is a fraction of a total amount, and the measures are related using a rule of three.
In this problem, 500 mg are equivalent to one cc. How many cc are equivalent to 250 mg? Hence the <em>rule of three</em> is given by:
500 mg - 1 cc
250 mg - x cc
Applying cross multiplication:
500x = 250
c = 0.5.
Hence option A is correct.

F
Work
So the answer to the original problem:
6-4.5 +(-8) equals -1.5
D,E,and F all yeild this answer.
Another way to do it is to simply rearrange the equation
D:
6-4.5 +(-8)
6-4.5-8
your just removing the parenthesis and swapping the sign
E:
6+(-4.5) -8
is the exact same as
6-4.5 +(-8)
you're just moving the parenthesis
F:
This one you're just adding a parenthesis and flipping the of
6-4.5 +(-8)
which turns it into
6+(-4.5)+(-8)
