6 0

Step-by-step explanation:

The data is already in ascending order.

The lower half of the data (120, 140, 160)

has the median 140.

180 is the median of the entire data.

The upper half of the data (200, 220, 240)

has the median 220.

Interquartile Range = 220 - 140 = 80.

Ginnie plans to paint a wall. She measures its height and width. She finds that she needs enough paint to cover 8 square meters.

SOVA2 [1]

Answer:

The 8 square meters represent the product of the height by the width of the wall and therefore, its area.

Step-by-step explanation:

Ginnie is going to paint a wall and measures the height and the width, the walls are usually in the form of a rectangle or square. To find the area of both we need to multiply the height by the width (in the case of the square both are the same) and this will give us the total amount of paint that we need to paint the wall.

In this example, Ginnie finds that she needs enough paint to cover 8 square meters, therefore, these 8 square meters represent the product of the height by the width (that we don't know but it doesn't matter) of the wall and therefore, its area.

On the number line if you are at positive 8 and add -8 you will lose 8 and get zero! Hope this helps!
