B. If you divide 8 into 25, you come up with 3.125.
A conditional statement is:
if p, then q.
so.... in the sentence...
-All dogs is the hypothesis
-Have tails is the conclusion.
The answer is:
A) if an animal is a dog, then it has a tail.
All the angles in a triangle equal 180 degrees so 128 + (5x+10) + 9x = 180
Group the like values to get 138 + 14x = 180
Subtract 138 from 180 to get 14x = 42
Divide 42 by 14 to get x = 3
Therefore x = 3
Consider such events:
A - selected student is freshmen
B - selected student is girl
- selected student is freshman is girl
- choosen girl is freshmen.
Use formula 
.
From the table you can see that girls that are freshmen are 4 from all 30 people, then 
. There are 18 girls, then 
. Substitute into the formula:
.
Answer: 
.
20/5=4 so 5x4 which means 2x4=8 so x is 8 hopes this helps
