Answer:
Collin mistake is step 1
correct answer 
Step-by-step explanation:
66% of the students are female AND study with Carl,
That means that (66% female) ÷ (80 % of all students) = 82.5% of Carl's yoga students are female.
The probability, therefore of that a randomly selected student of Carl's is female is
D) .83
A segment is only a "midsegment" if it connects midpoints. When labels above and below are 9 and 72, it is clearly not a midsegment. However, because it is parallel to the base, segments above and below on one side are proportional to those in similar positions on the other side.
72/9 = 56/(3x -20)
We can multiply by (3x -20)/8 to get
3x -20 = 7
3x = 27
x = 9
25/37= 0.676 which we must then multiply by 100 to arrive at an answer of 67.6 percent.
