What is the regression equation that represents the data in the table?
What is the regression equation that represents the data in the table?
y=-5.9273x+0.2554
y=0.0072x2+0.2627x-5.9916
y=0.2554x-5.9723
y=0.0072(0.2627)x
Bot GPT 3.5
answered
The regression equation that represents the data in the table is:
y = 0.0072x^2 + 0.2627x - 5.9916
Therefore, the correct choice is:
y = 0.0072x^2 + 0.2627x - 5.9916

What is the value of the function for the data set when x=7?
What is the value of the function for the data set when x=7?
-4.2357
-4.1845
-3.7999
-3.8512
Bot GPT 3.5
answered
To find the value of the function for the data set when x=7 using the regression equation, we substitute x=7 into the equation:
y = 0.0072(7)^2 + 0.2627(7) - 5.9916
y = 0.3543 + 1.8399 - 5.9916
y = -3.7974
Therefore, the value of the function for the data set when x=7 is approximately -3.7974.
None of the given answer options perfectly match this value. The closest option is:
-3.7999
