Answer:
The system will be found to be inconsistent or dependent.
Step-by-step explanation:
The matrix A will have no inverse for two different reasons:
- The system is inconsistent
- The system is dependent
In the latter case, the Gauss-Jordan method will find a set of parametric equations for a solution. In the former case, there is no solution.
The outcome will depend on the reason why there is no inverse.
The statement that is true is C
Answer:
1.8 or 9/5
Step-by-step explanation:
4
÷ 
Change into improper fractions
÷
Flip the second fraction and then multiply

=
18/10 is 1.8 as a decimal and 9/5 simplified
Answer:
She is an undergraduate because more undergraduates are enrolled
Step-by-step explanation:
From the question, we understand that:
Undergraduate > Graduate
<em>This represents the base rate</em>
So, when taking a guess using the base rate, your guess will be that: the woman is an undergraduate.
The reason for this is that you know that there are more undergraduates than graduates enrolled in the course.
The solution is 
.
Solution:
Given expression:
To solve this inequality.
Subtract on both sides of the inequality.
Switch the sides.
The solution is .
Now, graph the solution.
The solution of the graph is attached below.
