WILL GIVE BRAINLIEST! Find the solution sets to the following quadratic equations.
8. 5x^2 – 40 = 100

9. 9x^2 = 4x^2 + 10

10. x^2 – 4 = 80

11. x^2 + 25 = 100

12. 2x^2 + 7 = 67

13. (x^2 + 2^2)= 16

14. (x + 5^)2 = 23

15. (x – 4)^2 = 11

Given are five observations for two variables, x and y. xi 1 2 3 4 5 yi 3 7 5 11 14 which of the following is a scatter diagrams accurately represents the data? what does the scatter diagram developed in part (a) indicate about the relationship between the two variables? try to approximate the relationship betwen x and y by drawing a straight line through the data. which of the following is a scatter diagrams accurately represents the data? develop the estimated regression equation by computing the values of b 0 and b 1 using equations (14.6) and (14.7) (to 1 decimal). = + x use the estimated regression equation to predict the value of y when x = 4 (to 1 decimal). =
