Here are the steps on how I did it.
Answer:
1) (-50) <(-25) < (-10) < 10 < 25
2) 150 in^2
Step-by-step explanation:
For the first question we list the numbers according to their sign(start from negative)
For the second question we multiply height with width to find the area of the rectangle.
The range is the difference betweem the largest and smallest NUMBERS in the whole piece of data. The IQR is the difference between the largest and smallest QUARTILES. For example, if you had the data 1,2,3,4,5: 5-1=4 would be the range and...(4-2)=2 would be the IQR. Hope this helped! :)
It would be called an ecological model.
