Answer:
y=361
Step-by-step explanation:
187^2-174^2 = 4693
4693/13 = 361
13 x 361 = 4693
To solve this problem you must apply the proccedure shown below:
1- By definition, the formula for calculate the i<span>nterquartile range is
I</span><span>nterquartile range=Q3-Q1
Where Q1 is the lower quartile and Q3 is the upper quartile.
2-Keeping this on mind, you have:
</span>Interquartile range=Q3-Q1
<span>
Q3=245
Q1=201
</span>Interquartile range=245-201
Interquartile range=44
<span>
Therefore, the answer is: 44
