The following table was generated from the sample data of 10 junior high students regarding the average number of hours they are unsupervised per night, the average number of hours they play video games per night, and their final grades in their math class. The dependent variable is the final grade, the first independent variable (x1) is the number of hours unsupervised each night, and the second independent variable (x2) is the number of hours of video games each night. Intercept 64.821745 4.918050 13.180375 0.000012
Hours Unsupervised -1.691108 1.396989 -1.210538 0.271590
Hours Playing Video Games 6.796882 1.515248 4.485657 0.004167

Step 1 of 2: Write the multiple regression equation for the computer output given. Round your answers to three decimal places.

Step 2 of 2: Indicate if any of the independent variables could be eliminated at the 0.05 level of significance.

first, you divide the triangle in two, tô form a retangle triangle. after, using pythagoream theorem:

18^2 = 14^2 + (x/2)^2

(x^2/4) + 196 = 324

x^2/4 = 324 - 196

x^2/4 = 128

x^2 = 512

x = √512

x = √2^9

x = 16√2 cm

i hope i you.
