Hello!
Let's substitute the values for each ordered pair into the equation and see which one works.
4(3)-1=6+5
12-1=11
11=11
A is a solution
7=14
B is not a solution.
Therefore, a) only (3,2) is a solution to the equation.
I hope this helps!
122 degrees because supplementary angles are 180 degrees

Step-by-step explanation:
Using the given discrete distribution, it is found that the expected value is of $863.93.
<h3>What is the mean of a discrete distribution?</h3>
The expected value of a discrete distribution is given by the <u>sum of each outcome multiplied by it's respective probability</u>.
In this problem, the distribution of costs is given by:
Hence, the expected value is given by:
E(X) = 0.87 x 986 + 0.13 x 47 = $863.93.
