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.

Let,
- Mass of the steel be 108x
- Mass of the copper be 7x
- Then, Total mass = 108x + 7x = 115x
Given,
- Total mass of the coin = 230 mg
That means,
⇛ Total mass of the coin = 230 mg
⇛ 115x = 230 mg
⇛ x = 230 mg/115
⇛ x = 2 mg
Then,
- Mass of the steel = 108(2) = 216 mg
- Mass of the copper = 7(2) = 14 mg
☁️ ANSWER - 14 mg (Mass of copper)

Answer:
x=6
Step-by-step explanation:
Take -2 and add it to 10 and get 12. So then the equation is 2x=12. Divide 2 by 12 and get x=6.
Answer:
x = 6
Step-by-step explanation:
First, we need to cross multiply on both sides, which gives us:
9 * (5x - 6) = 27 * (2 + x)
45x - 54 = 54 + 27x
Now, we want to isolate x on either side.
We can substract 54 from both sides:
(45x - 54 = 54 + 27x) - 54
45x - 108 = 27x
We then subtract 45 from both sides:
(45x - 108 = 27x) - 45
-108 = -18x
Finally, we divide both sides by -18:
(-108 = -18x) / -18
6 = x
