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:
99
Step-by-step explanation:
110% × 90 = 99
<em>OR</em>
110/100 × 90 (Simplify this)
11/10 × 90 (Divide 10 into 90 / Cross multiply)
11 × 9 = 99
Answer:
You can look for these:
Step-by-step explanation:
The factors of the equation:
For example, if multiplication, the factors 2x2=4
if addition, the addends 2 + 2= 4
So just look for the numbers before the equal sign and any key words in the problem.
Hope this helps!
Answer:
g is decreasing for all x less than or equal to -1
Step-by-step explanation:
The graph of the function y = |x| looks like a "vee."
g(x) = |x + 1| - 7 moves that graph 1 unit to the <u>left</u><em> </em>(I know, it looks backwards!) and down 7 units. See attached image.
Function g(x) is decreasing for all
.
Correct answer is D).
A) and C) are polynomials, so x∈R, in B) we have √x, and in this case x ≥ 0.
