Please help me with this Ms. Gray studied her students' history test scores and sleeping habits. She found that students who slept less tended to earn lower scores on the test. What conclusion should she make?

There is no correlation between test score and amount of sleep.

There is a correlation between test score and amount of sleep. There is probably also causation. This is because there is a decrease in a student's test score with a decrease in the amount of sleep.

There is a correlation between test score and amount of sleep. There may or may not be causation. Further studies would have to be done to determine this.

the answers are in the images, i received 100% on this assignment. hope this !

p ÷ r = tan(x)

step-by-step explanation:

given that there is a figure below shows a right triangle: a right triangle is shown with hypotenuse equal to q units and the length of the legs equal to p units and r units.

graph is missing so i will create the graph as per given information.

the angle between the legs having lengths p units and q units is y degrees. the angle between the legs having lengths r units and q units is x degrees.

now we need to find about what is p ÷ r equal to.

so we can use trigonometric ratio tan(x)=[altitude]/[base] to find the value of p ÷ r, because p is the altitude and r is the base.

p ÷ r=tan(x)

hence final answer is p ÷ r=tan(x).

if you was gonna solve for a, a is a   < -12
