Answer:
The measures of a pair of same-side exterior angles are 10w and 5v. ... Find the measure of angles 1-7 given that lines m and n are parallel and t is transversal. ... Solve for x. 120= 15x +5+ 22x +4. 120 = 37% +. 4. (X=3]. 6. Use the following figure, given that ... Find the measure of angle 1. m24 = 123, mZ1 = 2x, mZ2 = x +42.
Step-by-step explanation:
Equation of the line perpendicular to x = -6 is y = -2
Step-by-step explanation:
The equation of a line in the slope-intercept force is
![y-y_0 = m(x-x_0)](https://tex.z-dn.net/?f=y-y_0%20%3D%20m%28x-x_0%29)
where
m is the slope
are the coordinates of a point on the line
In this problem, we have already a point on the line:
![(x_0,y_0)=(-1,-2)](https://tex.z-dn.net/?f=%28x_0%2Cy_0%29%3D%28-1%2C-2%29)
Concerning the slope, we are told that the line is perpendicular to the line
x = -6
This line is a vertical line: therefore, our line must be a horizontal line, so its slope is
![m=0](https://tex.z-dn.net/?f=m%3D0)
So now we can find the equation of the line:
![y-(-2)=0(x-(-1)\\y+2=0\\y=-2](https://tex.z-dn.net/?f=y-%28-2%29%3D0%28x-%28-1%29%5C%5Cy%2B2%3D0%5C%5Cy%3D-2)

Answer:
72 pieces
Step-by-step explanation:
since 1/8 pieces would mean 8 per pie then
8*9 = 72
So 72 pieces
Answer:
40 degrees
Step-by-step explanation:
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
