For the first event
P=3/(5+3)=3/8=0.375
Total became 2 red and 5 blue .... 7 total
For the second event
P=2/(5+2)=2/7= 0.2857
The unlabeled part of the right angle is complementary to 68 degrees, so 22 degrees. y is supplementary to 78 degrees, so 102 degrees. z as the third angle in the small triangle is 180 less than the sum of the other two,
z = 180 - 22 - 102
Answer: 56 degrees
The answer to #1 is D.
The answers to #2 is B,C,D,F.. I'm not sure what the remainder of G says..
select two points on the line, and plug into this formula y2-y1 over x2-x1
A is the mid point ==> AL = AB = 2AB
6x-17=2(2x+3) => 6x -17 = 4x +6 => 2x = 23 =>x=23/2
then just plug x into LB and AB
