The answer would be 6.25. 
Here's why:

Put all the numbers in order from least to greatest. 

Then find where the middle is.. once you've placed them in order it should be 14.5.
(I draw a line down the middle of the number) 

You have two separate halves now. 

Find the middle of the two halves, but since you have 4 numbers on each side you'll have to add two of the numbers together on each side and divide by two to get the number in the middle.

For the half on the least numbers side you'll add 11 and 11.5. This equals 22.5 then divide by 2 and this gives you 11.25.

For the half on the greater side you'd add 17 and 18. This equal 35 then divide by 2 and this gives you 17.5. 

The last step is to subtract 11.25 from 17.5 and this will give you the IQR. 

6.25

Courtney walks 1 mph slower than Brandi does. In the time that it takes Brandi to walk 6.5 mi, Courtney walks 5 mi. Find the spe
posledela

Answer:

Courtney's walking speed = 3.33mph

Brandi's walking speed = 4.33 mph

Step-by-step explanation:

Let x = Courtney's walking speed

then

(x + 1) = Brandi's walking speed

:

Time = Distance/speed

Brandi walks 6.5 mi time = Courtney walks 5 mi time

6.5/x + 1 = 5/x

Cross multiply

6.5x= 5(x+1)

6.5x= 5x + 5

6.5x - 5x = 5

1.5x = 5

x = 5/1.5

x = 3.33 mph is Courtney's walking speed

Note that:

(x + 1) = Brandi's walking speed

3.33mph + 1 = 4.33mph

Therefore,

Courtney's walking speed = 3.33mph

Brandi's walking speed = 4.33 mph

What is the area of the polygons by composition
sergeinik [125]
The rectangle has the dimensions 4 x 3. 
The measure of 6 ft is the triangle plus the square's length. 
The rectangle's length is 3. 
To find the triangle's width, solve this: 3 + x = 6 
Subtract 3 from each side to get x = 3. 
The dimensions of the triangle is 3 x 4. 
The area will be half of 3 x 4, so 12 / 2 or 6. 
The rectangle's area is 12 because its dimensions are 3 x 4. 
12 + 6 = 18 feet total. 

Hope this helps!

You can fold your paper on one, two, or more folds, but only on the folds we've already made. You can't make any new folds.
