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:
D
Step-by-step explanation:
point-slope form is y-y1=m(x-x1) . since the slope is 2 and not -2, you can automatically eliminate choices A and C. since the y-value in the point, (1,-1), is -1, you will add it to y because you are subtracting a negative. (- - = +) therefore, the final equation, in point-slope form, is y+1=2(x-1), or answer choice D.
