Given:
The two points C(2,-1) and D(5,3) on a coordinate plane.
To find:
The distance from C to D.
Solution:
The distance between two points is defined by the distance formula.
The two points are C(2,-1) and D(5,3). Using the distance formula, we get
On further simplification, we get
The distance from point C to D is 5 units. Therefore, the correct option is A.
Answer:
A multiple regression equation for this model can be expressed as:
Step-by-step explanation:
To model this problem as a multiple regression equation, we need to define which are the independent and dependent variables.
The dependent variable is the one which we want to predict for any set of independent variables values. This is the case of the driver's automotive insurance monthly premiums.
The driver's automotive insurance monthly premiums is the dependent variable "y".
The independent variables are the ones that explain the dependent variable variation. In this case there are: number of miles driven per week (x1); the age of the car, in years (x2); and the number of accidents in which the driver has been involved in the past 5 years (x3).
Then, a multiple regression equation for this model can be expressed as:
