Hi,
For this question, your answer would 40%.
All you had to was divide 160 by 400.
All probability chances equal 1.
So, subtract 1 and 7/11 to get your answer
The answer is 4/11.
Hope this helped!
The relation is between the x- values and y-values of the ordered pairs. The set of all x-values is called the domain and the set of all y-values is called the range
Answer:
<h2>A = 16.5 square units</h2>
Step-by-step explanation:
It's the right triangle.
The formula of an area of a right triangle:
Look at the picture.
We have
Substitute:
Answer:
x=−3 and y=7
Step-by-step explanation Solve: 7x+2y=−7for x:
7x+2y=−7
7x+2y+−2y=−7+−2y(Add -2y to both sides)
7x=−2y−7
