Can someone help me with algebraic method

Mathematics
1 answer:
Lina20 [59]3 years ago

Answer:

<em>x = -8; y = 0</em>

Step-by-step explanation:

x + 2y = -8

3x - 4y = -24

We will use the substitution method.

Solve the first equation for x.

x = -8 - 2y

Replace x of the second equation with <em>-8 - 2y</em>, and solve for y.

3<em>x</em> - 4y = -24

3<em>(-8 - 2y)</em> - 4y = -24

-24 - 6y - 4y = -24

-24 - 10y = -24

-10y = 0

y = 0

Now we substitute 0 for y in the first original equation and solve for x.

x + 2y = -8

x + 2(0) = -8

x + 0 = -8

x = -8

Solution: x = -8; y = 0

Which choice below is a boxplot for the following distribution? 67, 66, 64, 62, 60, 56, 54, 50, 46, 42, 41, 40, 40, 38, 35, 21,
luda_lava [24]

Answer:

Option E - Box plot E

Step-by-step explanation:

Given : Data,

67, 66, 64, 62, 60, 56, 54, 50, 46, 42, 41, 40, 40, 38, 35, 21, 19

To find : Which choice below is a boxplot for the following distribution?

Solution :

Step 1- Arranging the data from lowest to highest,

{19,21,35,38,40,40,41,42,46,50,54,56,60,62,64,66,67}  

Step 2 - Find the median of the data  

As the data is odd numbers so the median is \frac{n+1}{2} th term.

\frac{n+1}{2}=\frac{17+1}{2}=9th term.

9th term is 46

∴ Q_2=46  

Step 3 - To find Upper quartile and lower quartile  

Lower quartile data set is the median of the upper terms from median

{19,21,35,38,40,40,41,42}

Median of the set is M=\frac{38+40}{2}=39

∴ Q_1=39  

Upper quartile data set is the median of the lower terms from median

{ 50,54,56,60,62,64,66,67}

Median of the set is M=\frac{60+62}{2}=61

∴ Q_3=61  

We have plot the box plot attached below.

Our box plot is matched with Box plot E.

Therefore, Option E is correct.
