A coefficient of correlation of –0.80 a. Is a lower degree of relationship than r = 0.80 b. Is the same degree of relationship as r = 0.80 c. Is a higher degree of relationship than r = 0.80 d. Is impossible since correlation cannot be negative e. No comparison can be made between -0.80 and 0.80

Astudent draws two parabolas on graph paper. both parabolas cross the x-axis at (–4, 0) and (6, 0). the y-intercept of the first parabola is (0, –12). the y-intercept of the second parabola is (0, –24). what is the positive difference between the a values for the two functions that describe the parabolas? write your answer as a decimal rounded to the nearest tenth
