To solve for 
, we need to isolate it on one side of the equation.
Take the square root of both sides, making sure to use both positive and negative roots.
cannot be simplified, so we'll leave it as-is.
Add 
to both sides to fully isolate .
Expand the solution by making two solutions, one where is positive and one where it's negative.
Answer: The mean increases.
Step-by-step explanation:
The value of 0.9 mg/L is very low compared to a means of 7.6 mg/L with a standard deviation of 2.1 mg/L. It seems as though it is an outlier that is suffiently different from the others, and probably should be dropped from the data set. That would do 2 things: 1) the stabdard deviation will likely decrease, indicating a more confident data set, and 2) the mean vitamin C level will increase.
Answer:
The all common Factors of 24 are 1, 2, 3, 4, 6, 8, 12 and 24
To get the equivalent fractions, you simply have to multiply
the fraction with another fraction that would equal to 1.
2/8 x 2/2 (this is equal to 1) = 4/16; 1/4
3/8 x 2/2 = 6/16; 9/24
4/8 x 2/2 = 8/16; 1/2
So we have to use the distributive property:
We ll get -12x-9-2x+5+18x-24
Now we have to combine like terms
-12-2x+18x=4x
-9+5-24=-28
Therefore our answer is:
Y=4x-28
