These are the answers to the question
Suppose there are n observations in a data set consisting of the observations x1, x2, x3, ..., xn.
Rounding rule: round to one more decimal place than the highest number of decimal places contained in the data.
The formula can also be represented as sigma * xi / n.
x bar = SAMPLE MEAN
Mu = POPULATION MEAN
n= sample size
N= POPULATION SIZE
The sum of the deviations from the mean is always equal to 0.
The mean will always be pulled towards any outliers.
Ex: the average price of similar televisions at different stores. This is quantitative data that does not have outliers since the TVs at the different stores are similar
We can write (fg)(x) as: (fg)(x)=3x−6x−2. Factoring the numerator gives: .
Answer: I tried looking it up but I couldn't find anything, but I woud try typing in "4.1 Practice B (Whatever math that is) big ideas math blue answer key" and see if that works. Hope that helps:)
