The sum of squares is the method for finding the variation within the groups , between the groups and for the total sample.
Given an incomplete sentence about sum of squares.
We are required to fill the blank with the terms specified in options.
The sum of squares is basically the sum of the square of variation, where variation is defined as the spread between each individual value and the mean. In order to determine the sum of squares, the distance between each data point and the line of best fit is squared and then summed up. The line which is known as line of of best fit will minimize this value.
The sum of squares is the method for finding the variation within the groups, between the groups and for the total sample.In this method the variations between values are find out irrespective of whether it is of a group or not.
Hence the sum of squares is the method for finding the variation within the groups , between the groups and for the total sample.

Answer:
is the answer. Hope this helped!!
Step-by-step explanation:
X is the gcf so:
this is the maximum you can factor that too:
Answer:
Without any studying, the score would be about 328
Step-by-step explanation:
The y-intercept of an equation represents the point where its graph crosses the y-axis. At this point the value of x is always equal to 0.
The y-intercept of the equation in this context would represent the Math SAT score of a student who did not do any studying, that is the number of hours spent studying, x = 0.
Substitute x = 0 in the given equation and solve for y;
y = 24.387(0) + 328.182
y = 328.182
Therefore, Without any studying, the score would be about 328
Answer is A. Hope this helped
