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
A^2 + b^2 = c^2
5^2 + 7^2 = c^2
25 + 49 = c^2
74 = c^2
sqrt 74 = c
8.6 = c
so grant's to Isabelle's is 8.6 blocks, then from there to hannah's house, which is 7 blocks....so he walks a total of 8.6 + 7 = 15.6 blocks
It says estimate so I'm not sure if you want the exact answer but after calculating all of this I got 182.353745455
Hope this helps :)
