This is the answer for your question: y=3x+130
Answer:
B. At the corner of 10th Street and 17th Avenue.
Step-by-step explanation:
The point (x,y) which divides the segment AB with endpoints at
and
in ratio
has coordinates

In your case,

The fruit market (F) is three-fourths the distance from Tia’s home to Lei's home, then
or 
Thus,

So, the fruit market is at point
which ,=means it is placed at the corner of 10th Street and 17th Avenue.
QR =12 because you set up a proportion 21/14=x/8 then cross multiply and get 14x=168 then you divide and get 12
Answer:
N=27 participants
Step-by-step explanation:
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
The degrees of freedom for the model on this case is given by
where k =2 represent the number of variables.
The degrees of freedom for the error on this case is given by
. Sinc we know k we can find N.

And the total degrees of freedom would be 
On this case the correct answer would be N=27 participants
