Answer:



Step-by-step explanation:
The given probabilities are:


Their sum is 
The probabilities that will complete the model should add up to
so that the sum of all probabilities is 1.





Given:
The given system of equations is:


To find:
The solution to this system of equations by graphing.
Solution:
We have,


The table of values for first equation is:
x y
0 1
1 -1
Plot the points (0,1) and (1,-1) on a coordinate plane and connect them a straight line.
The table of values for second equation is:
x y
0 -4
2 -3
Plot the points (0,-4) and (2,-3) on a coordinate plane and connect them a straight line.
The graphs of given equations are shown in the below figure.
From the below figure, it is clear that the lines intersect each other at point (2,-3). So, the solution of the given system of equations is (2,-3).
Therefore, the solution to this system of equations is:
x-coordinate: 2
y-coordinate: -3
Answer:
<h3>The volume is 144.</h3>
Step-by-step explanation:
Volume of a rectangular solid = l × w × h
where
l is the length
w is the width
h is the height
From the question
l = 12 feet
w = 3 feet
h = 4 feet
Volume = 12 × 3 × 4
= 144 feet
Hope this helps you.
