An astronomer is interested in measuring in light years, the distance from his observatory to a distant star. If the astronomer believes that the values of the measurements are independent and identically distributed random variables with common mean LaTeX: dd (the actual distance) and a common variance of 9 (light years), how many measurements must he make to be 95% sure that his estimated distance is accurate to within + - 1.0 light year?

1. domain(-6,-1,1,5,7);range (-4,-1,2,4)/domain (1,-3,-2); range (-2,5,1)/domain(1,2,3,4,5,6);range(-1,0,1,2,3,6)

2. 1st and 4th are a function because if you draw a line vertically across it will only intersect it once.
