A 3d cardboard box has 6 sides, each of which are rectangles. If you unfold the 3D box, and flatten it out, then you'll be left with 6 rectangles such as what you see in the attachment below. This is one way to unfold the box. This flattened drawing is the net of the 3D rectangular prism. You can think of it as wrapping paper that covers the exterior of the box. There are no gaps or overlapping portions. If you can find the area of each piece of the net, and add up those pieces, that gets you the total area of the net. This is the exactly the surface area of the box.

In the drawing below, I've marked the sides as: top, bottom, left, right, front, back. This way you can see how the 3D box unfolds and how the sides correspond to one another. Other net configurations are possible.

<h3>Given Equation:</h3>

6 - 2n = -4n - 2 - 8

<h3>To Find:</h3>

The value of n.

<h3>Solution:</h3>

6 - 2n = -4n - 2 - 8

or, -2n + 4n = -2 - 8 - 6

or, 2n = -16

or, n = -16/2

or, n = -8

Using a correlation Coefficient calculator, the correlation Coefficient, r for the data = 0.127

The test statistic :

T = r² / √(1 - r²) / (n - 2)

Sample size, n = 10

Hence,

T = 0.127² / √(1 - 0.127²) / (10 - 2)

T = (0.016129 / 0.3506905)

T = 0.3506905

The value of the test statistic to 2 decimal places is 0.35

What does 8.3 × 10^ -5 in standard notation ​
xz_007 [3.2K]

Answer:

0.000083

Step-by-step explanation:

When you multiply by 10^-5, you're really multiplying by 0.00001. This multiplied by 8.3 is 0.000083. It also means that you just move the decimal place in 8.3 to the left five times, where you'll get the same answer.

PLEASE ASAP we need to turn in in 20 mins
satela [25.4K]

Answer:

14 units^2

Step-by-step explanation:

Hey there!

In order to find the area of this triangle, we need to find the base and height of the triangle

the base of the triangle is 7 units long and the height of the triangle is 4 units high

Formula for area of triangle: Base x Height x 1/2

7 x 4 x 1/2 --> 28 x 1/2 --> 14

So, the area of this triangle is 14

Now the question is asking to find the area by forming a parallelogram

All you have to do for this is duplicate that same triangle, and mirror it upside down

Then all you would have to do is find the Base and the Height and multiply them together
