STEP 1: Compute the mean
The mean of the dataset is the sum of the elements divided by their number:
STEP 2: Compute the residuals
You have to compute the difference between every element and the mean:
Step 3: Square the residuals:
Step 4: Sum the squared the residuals:
Step 5: Divide by the number of elements in the dataset:
Step 6: Consider the square root of the result:
The formula we used is
where 
is the standard deviation, 
are the elements in the dataset, 
is the number of elements in the dataset, and 
is the mean of the dataset.
The answer would be a would just have to look up 32% as a decimal
Answer:
Option 4.
Step-by-step explanation:
Reciprocal of the second fraction turns the product into the division of the two fractions, which equals to 1.
Two fractions are said to be the reciprocal or multiplicative inverse of each other, if their product is 1.
Answer: Thought I’d return the favor and help u with this question! But anyways, the axis of symmetry is at x = -3.
Explanatio: This can be found by looking at the basic form of vertex form:
y = (x - h)^2 + k
In this basic form the vertex is (h, k). By looking at what is plugged into the equation, it is clear that h = -3 and k = -4. This means the vertex is at (-3, -4).
It is a fact that the axis of symmetry is a vertical line of x = (vertex value of x). So we can determine that the axis of symmetry is at x = -3
i hope this helps u
Answer:
x=1
Step-by-step explanation:
3(x+2) - 4 = 2(x-1) +5
Distribute
3x +6 -4 = 2x -2 +5
Combine like terms
3x +2 = 2x +3
Subtract 2x from each side
3x-2x +2 = 2x-2x+3
x+2 =3
Subtract 2 from each side
x+2-2 = 3-2
x=1
