Using variable concepts, it is found that the amounts of time that different surgical procedures take at hospital is continuous.
<h3>What are continuous and discrete variables?</h3>
- Continuous variables: Can assume decimal values.
- Discrete variables: Assume only countable values, such as 0, 1, 2, 3, ...
In this problem, the amounts of time that different surgical procedures take at hospital can be decimal, for example 10.5 minutes, hence it is a continuous variable.

Answer:
killfuyy
Step-by-step explanation:
told you to shoot yourself
Step-by-step explanation:
the rate of change is officially
(f(x2) - f(x1)) / (x2 - x1)
but for a line function (as we have here) this is totally easy : it is the slope of the line.
and that means it is the factor of x.
in our case this is -3/2.
because the slope of a line is the ratio "y coordinate change / x coordinate change". and that is exactly corresponding to the general rate of change definition above.
Answer:
no solution
Step-by-step explanation:
12x − 18y = 27
4x − 6y = 10
Multiply the second equation by -3 so we can eliminate x
-3(4x − 6y) = 10*-3
-12x +18y = -30
Add the first equation to this new equation
12x − 18y = 27
-12x +18y = -30
------------------------
0 = -3
This is not a true equation, so there is no solution
