Answer:
I believe the answer for this is the 4.
Step-by-step explanation:
n/a
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 is 0.85 kilometers hope i helped
Answer:
-2c^2+4c
Step-by-step explanation:
4c^2+6c-6c^2-2c
combine like terms
4c^2-6c^2= -2c^2 and 6c-2c=4c
so
-2c^2+4c is the simplest form and the answer
