The following table was generated from the sample data of 10 college students regarding the number of parking tickets the student receives in a semester, the student'sage, and the student's GPA. The dependent variable is the student's GPA, the first independent variable (x1) is the number of parking tickets, and the second independentvariable (x2) is the student's age.InterceptCoefficients Standard Error15.034003 1.3027391-Statp-value11.540305 0.000025Number of Parking Tickets -0.026275 0.030254Student's Age-0.6383310.062922-0.868470 0.418515-10.144838 0.000053Copy DataStep 1 of 2: Write the multiple regression equation for the computer output given.

A rectangle is a four-sided figure that has two sets of parallel sides, so that we have two sides of one length and two sides of another length; a square is just a special case of a rectangle in which all four sides are the same length. Therefore, the procedure for calculating area is the same no matter whether we are dealing with a rectangle or a square. The area of a rectangle is calculated as follows: Area = base x height = b × h In this formula, the base is the width of the rectangle and the height is simply how tall the rectangle Is. For example, if we have a rectangle that is 20 centimeters wide and 10 centimeters tall, its area can be calculated as follows: Area = 20 cm x 10 cm = 200 cm² Note the superscript '2' In our answer; this is because we have multiplied centimeters by centimeters. In economics, we are more likely to be dealing with quantities bought or sold and prices, so don't worry about it too much for our discussion. The area of a triangle A triangle is really just a…
