Check the picture below.
we know that AL is an angle bisector, so the angle at A gets cuts into two equal halves, we also know the angle at B is 30°, so the triangle ABC is really a 30-60-90 triangle, meaning the angle at A is really a 60° angle, cut in two halves gives us 30° and 30° as you see in the picture.
if the angles at A and B, inside the triangle ABL, are equal, twin angles are only made in an isosceles by twin sides, that means that AL = BL.
Looking at the triangle ALC, we can see is also another 30-60-90 triangle, and we can just use the 30-60-90 rule to get x=CL.
•y-intercept is 20
•y-intercept represents how many glass bottles you need to earn $1.00 if you have 0 aluminum cans
•x-intercept is 50
•x-intercept represents how many aluminum cans you need to earn $1.00 if you have 0 glass bottles
I think its 1.012(500 - 100) = 400* 1.012 = 404.80 dollars
The Population mean is 3.3 and the Sample mean is 3.6, 3.6-3.3 is 0.3
The answer should be the second one
