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

Brut [27]

Answer:

C = 78 pi cm

Letting pi = 3.14

C = 244.92 cm

Letting pi =  pi button

C = 245.044227 cm

Step-by-step explanation:

We want to find the circumference

C = pi *d

C = pi *78

C = 78 pi cm

Letting pi = 3.14

C = 244.92 cm

Letting pi =  pi button

C = 245.044227 cm

Which function transforms the graph of y= x^2 so that it is first shifted down 4 units and its then reflected across the y- axis
GaryK [48]

Answer:

Option C. y= ( -x)^2 -4

Step-by-step explanation:

If we have a function f(x) = ax ^ 2 and we want to transform it into a function g(x) that is equal to f(x) displaced c units down on the y-axis, then we must do:

g(x) = f(x) -c

In this case we want to move the function 4 units down, then:

g(x) = f(x) -4\\\\g(x) = x ^ 2 -4

Finally, to reflect the function on the y-axis. must do y = g(-x)

Then we have the following function:

g(-x) = (-x) ^ 2 -4\\\\y = (-x) ^ 2 -4

The answer is option C
