If events x and y are independent, what must be true? check all that apply.
p(yx) = 0
p(xy) = 0
p(y|x) = p(y)
op(yx) = p(x)
p(x|y) = p(y)
o p(x|y) = p(x)

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).

d. corresponding side lengths in similar triangles are proportional in length.
