<h3>Answers: </h3><h3>Q1 = 6</h3><h3>Q3 = 21</h3>

The data is already sorted for us. If it wasn't, then you would have to write the values from smallest to largest.

The median is the middle most value 9 (in slot 4)

The median separates the data into two halves, which I'll call the lower and upper half

lower half  = {4,6,8}

upper half = {13,21,31}

The median of the lower half is 6, and this is the value of Q1.

The median of the upper half is 21. This is the value of Q3

If a five digit number is rounded to the ten thousands place is it possible for the rounded number to be a six digit number.
Bingel [31]
When rounding a number, the digit of the number can be increased up to 1, but the digit won't be decreased. So, it is possible to round a five digit number into six digit number. But to increase the number digit, the number should be rounded up. To be rounded up, a number should have value 5 or more.

Kelly has 7 1/4 yards of rope. She cuts 3 inches off each end of the rope. Kelly will divide the remaining rope into 5 equal pie
lana [24]
If you take 3 inches off each end, that means you will be taking 6 inches off. If you take 6 inches away from 7 1/4 yards ,(7 yards, 9 inches,) you get 7 1/12 yards (7 yards, 3 inches).

(7 1/12) / 5 = 1.426repeating

So each piece of rope will be (Approximately) 1.4 or 1 2/5 yards.


(I think.)
