Here is how to create a <span>conditional frequency table:

"1. It has to be a chart
2. Has to have two variables
3. Has to include the results of the variables"

Picture below:

Hope this helps!

Solve for x and y.<br><br> 4x-3y=16<br> -2x+4y=-2<br><br> DUE 2/7/17!

$\left \{ {{4x-3y=16\:(I)} \atop {-2x+4y=-2\:(II)}} \right.$

<span>Multiply the 2nd equation by (-4). This will eliminate the x's when you add the two new equations together.
</span> $\left \{ {{4x-3y=16\:\:\:\:\:\:\:\:\:\:} \atop {-2x+4y=-2\:*(-4)}} \right.$
$\left \{ {{\diagup\!\!\!\!4x-3y=16} \atop {-\diagup\!\!\!\!4x+8y=-4}} \right.$
--------------------
$5y = 12$
$\boxed{\boxed{y = \frac{12}{5}}}\end{array}}\qquad\quad\checkmark$

Let's replace the value found in the first equation:
$4x-3y=16\:(I)$
$4x-3*( \frac{12}{5}) =16$
$4x - \frac{36}{5} = 16$
least common multiple (5)
$\frac{20x}{\diagup\!\!\!\!5} - \frac{36}{\diagup\!\!\!\!5} = \frac{80}{\diagup\!\!\!\!5}$
$20x - 36 = 80$
$20x = 80 + 36$
$20x = 116$
$x = \frac{116}{20} \frac{\div4}{\div4} \to\: \boxed{\boxed{x = \frac{29}{5} }}\end{array}}\qquad\quad\checkmark$

Find the radius pls. help

MA_775_DIABLO [31]

Good morning,

Answer:

Step-by-step explanation:

V = h × (base area)

= 12 × (π×r²)

then 192π = 12π×r²

Then 192 = 12×r²

Then r² = 192÷12 = 16

Then r = √16 = 4.

rewona [7]

Answer:

Cups of soup to be prepared = 320

Step-by-step explanation:

Using equivalent ratios

2:5 = X:800

X = (800 x 2)/5 = 320 cups

Cups of soup to be prepared = 320

Multiply the following using the vertical method

Svetradugi [14.3K]

Answer:

Option C is correct.

Step-by-step explanation:

We need to multiply the following terms using vertical multiplication method

3x^2-5x+1

x x^2+2x+4

The vertical multiplication is shown in the figure attached.

The result is: 3x^4+x^3+3x^2-18x+4

So, Option C is correct.

Please help me on these! I really don't get it and I have to get them done!

Mandarinka [93]

Hey there :)

All these shapes are known as a rhombus.
The are formula of a rhombus is $\frac{(side1)(side2)}{2}$

1st ) The area is given = 48 in²
The diagonals are 1) 8 in and 8 in = 16 in , 2) x in and x in = 2x in

Apply the formula to find x
$48=\frac{(16)(2x)}{2}$
48 = 16x

Divide by 16 on either side to isolate x
$\frac{48}{16}= \frac{16x}{16}$
3 = x

Check:
Area = $\frac{(8+8)(3+3)}{2}$
= $\frac{96}{2}$
= 48 in²

2nd ) Area is given = 48 ft²
The diagonals are 1) 4 + 4 = 8 ft , 2) x

Apply the formula to find x
48 = $\frac{(8)(x)}{2}$
48 = 4x

Divide by 4 on either side
$\frac{48}{4} = \frac{4x}{4}$
12 = x

Check:
Area = $\frac{(4+4)(12)}{2}$
= $\frac{96}{2}$
= 48 ft²

3rd ) Given diagonals are 19 ft and 38 ft
Area = $\frac{(19)(38)}{2}$
= $\frac{722}{2}$
= 361 ft²
