Step-by-step explanation:
First we must calculate the interquartile range (IQR), using this equation:
Based on the information provided we fill in:
In order to find what the range for the data set is we need to use the Interquartile Rule:
× 
×
× 
Now we plugin in:
Any number below 25.5 is a possible outlier and any number above 77.5 is a possible outlier.
Answer:
Based on the results of the calculations, 25 could be a possible outlier in the data set.
Answer:
<em>Use a variable for the input and write the rule. Then, see if the function rule works for each term in the table by plugging the input into the expression and seeing if it equals the listed output. Substitute the input values in for in the function to see if you get the results in the output column.</em>

Answer: Marc still owes $175
Step-by-step explanation:
Let x represent the cost of the rug.
Marc ordered a rug and gave a deposit of 30% of the cost and will pay the rest when the rug is delivered. This means that the amount of money that he deposited
for the rug is
30/100 × x = 0.3 × x = 0.3x
If the deposit was $75, it means that
0.3x = 75
x = 75/0.3 = 250
The cost of the rug is $250
The amount that Marc still owes would be
250 - 75 = $175
