You use a line of best fit for a set of data to make a prediction about an unknown value. The correlation coefficient for your data set is 0.833. . Can you be confident that your predicted value will be reasonably close to the actual value? Why or why not? Will mark brainliest for ACTUAL ANWSERS. Please, this is the only question left on the entire assignment and I don't understand it at all. I really need this anwser.

hint: which coefficient is a multiple of 360°?

step-by-step explanation:

alright so i think for this one it would to draw it out. this may be hard for me to try and draw, but i will do my best on here:

        r

  /       |     \

notice how it forms 2 triangles inside one bigger triangle.

so if we know the angle spr is the same as psr that is saying the measure of angle p is the same as angle s. this means the big triangle psr is either isosceles or equilateral. in both cases, the triangle is perfectly symmetrical when split down the middle, which is in this case rq. because we know it is perfectly symmetrical on both sides, we know that the two triangles inside the bigger one are equal.
