Answer:
Qualitative variable.
See explanation below.
Step-by-step explanation:
In research we have two types of variables: the quantitative and the qualitative variables.
- A quantitative variable is a variable that is a number, for example: age, height, number of years of school. These type of variables are only numbers.
- A qualitative variable is a variable that is not a number but rather a category of data. For example: your name, your gender, your favorite food. All these examples are not numbers but categories.
In this example we are asked about our favorite city, we can see that the possible answers for this question are: Dallas, Seattle, Washington, Paris, etc.. these are not numbers so therefore this is an example of qualitative variable.
I think the answer of 1.62 / 0.27 is 6.

Answer:
(−4, −8), because the point satisfies both equations
Step-by-step explanation:
Line A
y = x - 4
Line B
y = 3x + 4
If we equate those 2 equations
x - 4 = 3x + 4
2x = -8
x = -4
y = -8

Answer:
58. 2 real roots; see attached for a graph
59. -6, 3
Step-by-step explanation:
58. A graphing calculator graphs this easily. The graph is shown in the attachment. There are 2 x-intercepts, hence 2 real roots.
__
59. The x-intercepts are (-6, 0) and (3, 0), so the x-values x=-6 and x=3 satisfy the equation y = 0.
