Astudent shines a light through a prism which causes a rainbow to form onto a piece of paper. the student then places
a thermometer in each color of light (a thermometer in the red light, a thermometer in the orange light, a thermometer in
the yellow light, etc) for two hours. the student then records the temperature displayed on each thermometer
the dependent variable in this experiment is

the color of the light

the temperature in each color of light

the time the thermometer sits in each color of light

the size of the paper

Astudent found the solution below for the given inequality. |x-9|< -4 x-9> 4 and x-9< -4 x> 13 and x< 5 which of the following explains whether the student is correct? -the student is completely correct because the student correctly wrote and solved the compound inequality. -the student is partially correct because only one part of the compound inequality is written correctly. -the student is partially correct because the student should have written the statements using “or” instead of “and.” -the student is completely incorrect because there is no solution to this inequality.
