Answer:
b. The sum of the squared deviations between each group mean and the mean across all groups
Step-by-step explanation:
Previous concepts
Analysis of variance (ANOVA) "is used to analyze the differences among group means in a sample".
The sum of squares "is the sum of the square of variation, where variation is defined as the spread between each individual value and the grand mean"
Solution to the problem
If we assume that we have
groups and on each group from
we have
individuals on each group we can define the following formulas of variation:
And we have this property
As we can see the sum of squares between represent the sum of squared deviations between each group mean and the mean across all groups.
So then the best option is:
b. The sum of the squared deviations between each group mean and the mean across all groups
The key thing to look for to determine whether a sequence is geometric is to see whether the ratio between consecutive terms - the number I would multiply one term by to get the next - is constant.
By inspection, we see that the fourth answer choice satisfies that, as
Why not the first? We have 
The third choice is not a geometric sequence, but rather an arithmetic sequence, where the difference between consecutive terms is constant. Just to make sure that it isn't geometric, we compute 
The second sequence is not geometric (although it does eventually converge to 1, but not its corresponding series), as 
Answer:
try c
Step-by-step explanation:
To get the total cost, add the tax rate to 1, then multiply that by the price of the cartridge:
Total: 17.50 x 1.0925 = $19.12
