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

-x + 4y when x = -4/5 and y = 1/3
Usimov [2.4K]

we have the expression

-x+4y

Evaluate for x=-4/5 and y=1/3

substitute the values of x and y in the given expression

\begin{gathered} -(-\frac{4}{5})+4(\frac{1}{3}) \\ \frac{4}{5}+\frac{4}{3} \\ \frac{3\cdot4+5\cdot4}{15} \\ \frac{32}{15} \end{gathered}

the answer is 32/15

Why does (-4 1/2)^2 = 20.25? Thank you please hurry!
AnnZ [28]

Answer:

See below.

Step-by-step explanation:

Squaring a number means to multiply the number by itself.

For example, 3^2 means 3 * 3.

8^2 means 8 * 8.

(-6)^2 means (-6) * (-6).

In each case above, you see that the number that is squared is multiplied by itself.

In this case, (-4.5)^2, squaring the number -4.5, means multiply the number -4.5 by the number -4.5

(-4.5)^2 = (-4.5) * (-4.5)

Now we need to actually multiply -4.5 by -4.5

When you multiply a negative number by a negative number, the result is positive, so the product of -4.5 and -4.5 is a positive number. To find that number, you multiply 4.5 by 4.5

4.5 * 4.5 = 20.25

Therefore, (-4.5)^2 = 20.25
