Suppose iq scores were obtained for 20 randomly selected sets of twins. the 20 pairs of measurements yield x overbarequals99.23, y overbarequals98.1, requals0.917, p-valueequals0.000, and modifyingabove y with caret equals negative 1.76 plus 1.01 x, where x represents the iq score of the twin born first. find the best predicted value of modifyingabove y with caret given that the twin born first has an iq of 103? use a significance level of 0.05.

answer:

c) the x-coordinate of the center of the circle increases by 3

the answer is c 150

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.

8 < i think

hope this !
