The newest invention of the 6.431x staff is a three-sided die. on any roll of this die, the result is 1 with probability 1/2, 2 with probability 1/4, and 3 with probability 1/4. consider a sequence of six independent rolls of this die. find the probability that exactly two of the rolls result in a 3.

answer:

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

step-by-step explanation:

points a and b are equidistant from the desired line, so the line you find by using them will go through point r.

using points other than a and b will give the desired line only if they are equidistant from r. if they are randomly located, the perpendicular line you create will not necessarily go through point r, hence will not be a solution to the problem.

i think its 7.6

if so your welcome

im super bad at school but u for some reason need to have points to ask questions and you get points by answering so thats all im doing sorry for t r o l l i n g
