Let x represent the number of red marbles, then blue marbles are represented by x + 31
red + blue = 225
x + x + 31 = 225
2x + 31 = 225
2x = 194
x = 97
Blue: x + 31 = 97 + 31 = 128
Answer: 128 blue marbles

Answer:
The IQR is given by:

If we want to find any possible outliers we can use the following formulas for the limits:


And if we find the lower limt we got:


So then the left boundary for this case would be 3 days
Step-by-step explanation:
For this case we have the following 5 number summary from the data of 144 values:
Minimum: 9 days
Q1: 18 days
Median: 21 days
Q3: 28 days
Maximum: 56 days
The IQR is given by:

If we want to find any possible outliers we can use the following formulas for the limits:


And if we find the lower limt we got:


So then the left boundary for this case would be 3 days
This is infinite since the sequence can go on forever. The sequence increases by 1b every time and the end number is increased 1 every time as well.
