What is the median of the data?
eimsori [14]
<span>20, 19, 13, 23, 16, 15, 17, 17, 15, 15, 22, 19

</span>To find the Median, place the numbers in value order<span> and find the </span>middle<span>.
</span>
13, 15, 15, 15, 16, 17, 17, 19, 19, 20, 22, 23

There are 12 numbers and so we don't have just one middle number, we have a pair of middle numbers:


13, 15, 15, 15, 16, (17, 17), 19, 19, 20, 22, 23

<span>To find the value halfway between them, add them together and divide by 2:
</span>
17 + 17 = 34
34 ÷ 2 = 17

So the median is A) 17.

PLEASE HELP ME I WILL MARK BRAINLYEST
Korvikt [17]

                               Question 9:

Given the equations

5x+2y=6;

4x-8y=0

solving the system of the equations

\begin{bmatrix}5x+2y=6\\ 4x-8y=0\end{bmatrix}

\mathrm{Multiply\:}5x+2y=6\mathrm{\:by\:}4\:\mathrm{:}\:\quad \:20x+8y=24

\mathrm{Multiply\:}4x-8y=0\mathrm{\:by\:}5\:\mathrm{:}\:\quad \:20x-40y=0

\begin{bmatrix}20x+8y=24\\ 20x-40y=0\end{bmatrix}

20x-40y=0

-

\underline{20x+8y=24}

-48y=-24

\begin{bmatrix}20x+8y=24\\ -48y=-24\end{bmatrix}

-48y=-24

\frac{-48y}{-48}=\frac{-24}{-48}

y=\frac{1}{2}

y = 0.5 ( 0.5 is the result of rounding 0.5 to the nearest 0.01)

\mathrm{For\:}20x+8y=24\mathrm{\:plug\:in\:}y=\frac{1}{2}

20x+8\cdot \frac{1}{2}=24

20x+4=24

\frac{20x}{20}=\frac{20}{20}

x=1.00 ( 1.00 is the result of rounding 1 to the nearest 0.01 )

So, the solution is:

(x, y) → (1.00, 0.5)

                            Question 10)

Similarly the question 10 can be solved.

Given the equations

5x+2y=9;\:4x-3y=44

solving

\begin{bmatrix}5x+2y=9\\ 4x-3y=44\end{bmatrix}

\mathrm{Multiply\:}5x+2y=9\mathrm{\:by\:}4\:\mathrm{:}\:\quad \:20x+8y=36

\mathrm{Multiply\:}4x-3y=44\mathrm{\:by\:}5\:\mathrm{:}\:\quad \:20x-15y=220

\begin{bmatrix}20x+8y=36\\ 20x-15y=220\end{bmatrix}

20x-15y=220

-

\underline{20x+8y=36}

-23y=184

\begin{bmatrix}20x+8y=36\\ -23y=184\end{bmatrix}

-23y=184

y=-8.00   ( -8.00 Rounded to the nearest 0.01 or  the Hundredths Place )

\mathrm{For\:}20x+8y=36\mathrm{\:plug\:in\:}y=-8

20x+8\left(-8\right)=36

20x=100

x=5.00  ( 5.00 Rounded to the nearest 0.01 or  the Hundredths Place )

So, the solution is:

(x, y) → (5.00, -8.00)

7d – 4d – 3d – 5 = 6d
vazorg [7]

Answer:

d = -\frac{5}{6}

Step-by-step explanation:

7d – 4d – 3d – 5 = 6d

<em>(7d - 4d = 3d)</em>

3d - 3d -5 = 6d

<em>(3d - 3d = 0)</em>

0 - 5 = 6d

-5 = 6d

-5/6 = 6d/6

d = \frac{-5}{6}

Hope this helps ^-^
