Answer:
y = 3x - 2
Step-by-step explanation:
<em>use y = mx + b</em>
y = -2
x = 0
m (slope) = 3
b (y-intercept) = -2, <em><u>since the point (0,-2) passes through the y a</u></em>xis.
<em>put is as slope-intercept form:</em>
y = 3x - 2
Answer:
Option C. Quantitative, because numerical values, found by either measuring or counting, are used to describe the data.
Step-by-step explanation:
We are given the following in the question:
Variable: Final exam scores (from 0 to 100) for graduating high school seniors.
The following variable is a quantitative variable.
Quantitative variable:
- Their values are expressed in numerical.
- They are either measured or counted.
- Descriptive terms are not used to describe them.
- They can either be continuous or discrete.
Since final scores have numerical values and are counted, they are quantitative variables.
Option C. Quantitative, because numerical values, found by either measuring or counting, are used to describe the data.
Level of measurement:
A score of zero means no true existence for score. That is true zero exist.
Thus, it is ratio because difference between the values in data can be compared meaningful and they have a true zero.
Answer:
A = -12, B = 9 and C = .2
Step-by-step explanation:
So it just looks like we need to use algebra to move everything around to get it in the form Ax + By = C
So, let's start with 9y = 12x + 0.2. From standard form we have all terms wth variables on one side, so let's do that. the right sie has both a variable term and non variable term, so let's get rid of the variable term. The variable term is 12x, so to get rid of it you subtract 12x from both sides.
9y = 12x + 0.2
9y - 12x = 0.2
To make it exactly in standard form just rarrnge.
-12x + 9y = 0.2
So now we have A = -12, B = 9 and C = .2
