When adding or subtracting with powers, the terms that combine always have exactly the same variables with exactly the same powers. Because the variables are the same (x) and the powers are the same (there are no exponents, so the exponents must be 1), you can add the variables.

Romashka-Z-Leto [24]

Answer:

The Interquartile range is 10.

Step-by-step explanation:

First, we will need to find the mean, the mean of this sequence is 16, you will now need to find quartile 1 and quartile 3. Quartile 1 is 13, and quartile 3 is 23. Lastly, subtract Quartile 3 and Quartile 1 will be the answer.

So, 23-13=10

The Answer will be 10, the interquartile range is 10.

Hope this helps!
