Answer:
b. used to predict the dependent variable called the intervening variable
Step-by-step explanation:
The variable of interest is also known as response variable or dependent variable, are named the predictors, or independent variables in the regression. By the other hand, the dependent variable is known as the variable of interest or "Y" and usually the independent variables are expressed by "X".
Based on this definition we can analyze one by one the possible options:
a. used to predict other independent variables
No, the independet variable is not used to predict other independt variables, the independent or the intependent variables X's are used to predict the dependent variable Y
b. used to predict the dependent variable called the intervening variable
Yes, the practical use of the independent variables are predict the dependent variable Y.
c. the variable that is being predicted
No, the independent variable X is not the variable that would be predicted, the Dependent variable Y is the variable that would being predicted.
130
srv is a straight line so angleSRV=180
TRV and SRT make up SRV so TRV + SRT = SRV.
(x-10) + (2x+10) = 180.
the 10s cancel each other out so 3x = 180
so x=60 bc 180/3=60. sub 60 for x in TRV and u get 130. sub 60 for x in SRT and you get 50, which, with 130 makes 180, so the answer is correct!
Answer:
slope = 2
Step-by-step explanation:
The ordered pairs are (2,3) and (5,9).
It is given that the function is linear.
Since it is linear, the graph of the function is a straight line.
Slope of the straight line is constant at all points lying on it.
Slope of a straight line containing the points 
and 
is given by:
.
Slope of the straight line containing (2,3) and (5,9) is given by:
.
