Answer: 125ft
Step-by-step explanation:
In the model, we have the relation:
2in = 25ft
This means that 2 inches in the model represent 25ft for the actual college campus.
Then, if the building is 10 inches tall in the model, we have:
How many groups of 2 inches we have in 10 inches?
10in/2in = 5
And we know that each one of these 2 inches represent 25ft, then 5 of them are 5 times 25 ft:
The height of the building is 5*25ft = 125ft
the data represents the heights of fourteen basketball players, in inches. 69, 70, 72, 72, 74, 74, 74, 75, 76, 76, 76, 77, 77, 8

If you would like to know the interquartile range of the new set and the interquartile range of the original set, you can do this using the following steps:
<span>The interquartile range is the difference between the third and the first quartiles.
The original set: </span>69, 70, 72, 72, 74, 74, 74, 75, 76, 76, 76, 77, 77, 82
Lower quartile: 72
Upper quartile: 76.25
Interquartile range: upper quartile - lower quartile = 76.25 - 72 = <span>4.25
</span>
The new set: <span>70, 72, 72, 74, 74, 74, 75, 76, 76, 76, 77, 77
</span>Lower quartile: 72.5
Upper quartile: 76
Interquartile range: upper quartile - lower quartile = 76 - 72.5 = 3.5
The correct result would be: T<span>he interquartile range of the new set would be 3.5. The interquartile range of the original set would be more than the new set.</span>

Step-by-step explanation:
Answer:
B. use multipliers -3 and 2
Step-by-step explanation:
If you're solving the system by "addition," multiplying the equations by the chosen numbers needs to result in opposite coefficients for one of the variables.
<h3>Effect of answer choices</h3>
A. The system becomes ...
- 12x -6y = 21
- 12x -12y = 60
No variable has opposite coefficients.
__
B. The system becomes ...
- -12x +6y = -21
- 6x -6y = 30
The y-variable has opposite coefficients. This is a good choice.
__
C. The system becomes ...
No variable has opposite coefficients.
__
D. The system becomes ...
- 4/3x -2/3y = 7/3
- 3x -3y = 15
No variable has opposite coefficients.
__
<em>Additional comment</em>
The simplest "no brainer" solution is to use the coefficients of one of the variables, negating one of them. Multiply each equation by the opposite equation's coefficient. Here, the y-coefficients are -2 and -3, and the multipliers of answer choice B are -3 and 2, consistent with this advice. (The sign of 2 was changed.)
