(05.01)a scale drawing of a living room is shown below. the scale is 1 : 40.

a rectangle is shown. the length of the rectangle is labeled 6 inches. the width of the rectangle is labeled 4 inches.

show your work to determine the area of the room in square feet.

Step-by-step explanation:

we know that

The scale is

That means

1 unit in the drawing represent 40 units in the actual

or

1 inch in the drawing represent 40 inches in the actual

step 1

Find the actual dimensions of the living room

Multiply the dimensions of the living room in the drawing by 40

step 2

Convert inches to feet

Remember that

To convert inches to feet , divide by 12

so

step 3

Find the area in square feet

Multiply the length by the width

Convert to mixed number

solution:

as, mean is defined as sum of all the observations divided by total number of observations.

and , median is mid value of the data whether arranged in ascending order or descending order.

consider, roadsters:

2,3,4,5,6,7,8,9

mean =

also, median= , because number of observations is even, so median is mean of two mid values.

now, coming to bandits

2,3,4,5,6

mean =  

median = 4, as number of observations is odd.

so, roadsters has greater median as well mean than bandits.

→option a is true about the repairs performed on 2 types of cars:

bandits have lower median and mean than roadsters.
