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! :)
Do you have a picture of the graph, I cant help u with out it. :)

<h3>3
Answers:</h3>
- Coefficient is -8
- Terms are 15 and -8x
- Constant is 15
Explanation:
The coefficient is the number just to the left of the variable. So that's why -8 is the coefficient for -8x. This is the variable term while 15 is the constant (it has no variable multiplied with it). The two terms are 15 and -8x since we can write 15-8x as 15+(-8x). Terms are separated by a plus sign.
Step-by-step explanation:
Sale price
= Marked down by 10% from selling price
= 90% of selling price
= 0.9 * $600
= $540.
Sale price - Cost price
= $540 - $450 = $90.
The markup from cost to sale is $90.
