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.
![N=24+k+1=24+2+1=27](https://tex.z-dn.net/?f=N%3D24%2Bk%2B1%3D24%2B2%2B1%3D27)
And the total degrees of freedom would be ![df=N-1=27 -1 =26](https://tex.z-dn.net/?f=df%3DN-1%3D27%20-1%20%3D26)
On this case the correct answer would be N=27 participants
665%
percent means parts out of 100
665%=655/100=6.55
'of' means mutliply
so you gots do do that first
655% of 568766=6.55 times 568766=3725417.3
now we gots
5+3725417.3-557899
add
3725422.3-557899
subtraact
3167523.3=y
Answer:
pliz u substrate first so that i can solve easily
Part 1:
First figure out how many apples she has. She bought 3 bags, each bag holds 12 apples. 3 * 12 = 36. So she has 36 apples in total. She needs 8 apples to make one pie. We can divide this by the total number of apples to figure out how many pies she can make.
36 / 8 = 4.5
So she can make 4.5 pies, or since this is real-life context, she can only make 4 pies.
Part 2:
To make 6 pies, she needs to have 8 apples for each pie. 8 * 6 = 48. So she needs 48 apples. She only has 36 apples now, 48 - 36 = 12. So she needs to buy 12 more apples if she wants to make 6 pies. Each bag holds 12 apples, so she needs to buy 1 more bag of apples.
Answer is -8/21 hope this helps
