Answer:

Step-by-step explanation:

The interquartile range is the difference between the upper quartile and the lower quartile.

The first step is to find the median which is the middle value of the data set arranged in ascending order.

10, 11, 12, 15, 17, 19, 22, 24, 29, 33, 38

↑ ↑median ↑

The lower quartile is the middle value to the left of the median.

The upper quartile is the middle value to the right of the median.

The lower quartile = 12 and the upper quartile = 29

Interquartile range = 29 - 12 = 17

3x + 1 = 2x – 3 Why can't you add 3x with 2x? And what should you do for the first step

Tamiku [17]

Answer:

You can’t add 3x with 2x because to get term to the other side of the equal sign, you need to do the inverse (opposite) of the number. Since 3x is positive (basically with a + in the front) you SUBTRACT 3x for it to get to the other side. Which will get u -1x or just -x.
