Answer:
Use the difference in sample means (500 − 529) in a hypothesis test for a difference in two population means (or treatment effect).
Hmm...
that would be 1/8 or 0.125%
<span>give a thx if you liked the answer!</span>
Since the ratio is 4:9 your trying to find the sum. What I mean is that if it's 4 to 9, whats 20+9? =29. Do the same for 4. 20+4= 24. Now you find the difference in order to find how much does Byron have compared to Jonathan. So 29-24= 5
Coordinates will show the vertices of the triangle, and using the vertices, calculate length of the sides of the triangle.With the side length you can now calculate the angles of the triangle.
Step-by-step explanation:
The coordinates of the triangle can be plotted on a graph tool to give you the exact shape.Then using the coordinates that represent vertices for the triangle, apply the distance formula; 
This gives the length of the sides of the triangle.With the side length values, you can apply the cosine rule : c²=a²+b²-2ab cos c to find the angles in the triangle.
