Answer:
2(x+45)
Step-by-step explanation:
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.
Hi there!
The question here gives us an inequality, and it tells us to solve for x.
![\frac{1}{3} (6x+24)-20 \ \textless \ - \frac{1}{2} (6x-36)](https://tex.z-dn.net/?f=%20%5Cfrac%7B1%7D%7B3%7D%20%286x%2B24%29-20%20%5C%20%5Ctextless%20%5C%20%20-%20%5Cfrac%7B1%7D%7B2%7D%20%286x-36%29)
First, use the distributive property to simplify both sides of the equation.
![2x+8-20\ \textless \ -3x+18](https://tex.z-dn.net/?f=2x%2B8-20%5C%20%5Ctextless%20%5C%20-3x%2B18)
Now, on the left side of the inequality, combine like terms.
![2x-12\ \textless \ -3x+18](https://tex.z-dn.net/?f=2x-12%5C%20%5Ctextless%20%5C%20-3x%2B18)
Add 12 to both sides.
![2x\ \textless \ -3x+30](https://tex.z-dn.net/?f=2x%5C%20%5Ctextless%20%5C%20-3x%2B30)
Add 3x to both sides.
![5x\ \textless \ 30](https://tex.z-dn.net/?f=5x%5C%20%5Ctextless%20%5C%2030)
Divide 5 from both sides.
![x\ \textless \ 6](https://tex.z-dn.net/?f=x%5C%20%5Ctextless%20%5C%206)
Therefore, the solution to the inequality is anything less than 6, or
x < 6. Hope this helped!
Answer:
58+40e−t/2458+40e−t/24
step by step explanation:
Normally, the temperature of a corpse is the temperature of the surrounding environment.
This is done by losing or gaining heat to equilibrate to that of the surrounding.
Let's assume that the final temperature of the corpse is after t hrs.
Then the temperature of the surrounding in degree Fahrenheit is equal to 58+40e−t/2458+40e−t/24
