Answer:
And then
C. 240
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"
When we conduct a multiple regression we want to know about the relationship between several independent or predictor variables and a dependent or criterion variable.
If we assume that we have
independent variables and we have
individuals, we can define the following formulas of variation:
And we have this property

If we solve for SSR we got:
(1)
And we know that the determination coefficient is given by:

We know the value os
and we can replace SSR in terms of SSY with the equation (1)

And solving SSY we got:


And then
C. 240
Answer:
I'm not sure how to answer is but i think its called < CDE or < EDC or it is an acute angle.
Step-by-step explanation:
Answer:
$620 every year
Step-by-step explanation:
Since the question didn't specify how long she would have to save for, let's just assume that it's one year. There are 52 weeks in a year which is $520, and on her birthday she would have an extra $100, so every year she saves $620 in total.
This triangle would be acute none of the angles are greater than or equal to 90.
