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.

Answer:
infinite solutions
Step-by-step explanation:
Answer:
height of the tower = 2358.3 feet
Step-by-step explanation:
To solve this question, we can use the tangent relation of the angle of elevation, where the opposite side of the angle is the height of the tower minus six feet and the adjacent side of the angle is the distance from David to the tower. So, we have that:
tangent(78) = (height - 6)/500
4.7046 = (height - 6) / 500
height - 6 = 2352.3
height = 2358.3 feet
We know the total distance and individual times, so we can sum and equate total distance.
Let
E=speed heading east
E+45=speed heading south
then
4(E+45)+6E=3370 miles
Solve for E:
4E+180+6E=3370
10E=3370-180=3190 mph
E=319 mph.
