The distribution is considered the mean in the problem

Step-by-step explanation:

$124.84 - $19.75 = $105.09

If you can consider what the mean is in math: How to Find the Mean. The mean is the average of the numbers. It is easy to calculate: add up all the numbers, then divide by how many numbers there are. In other words it is the sum divided by the count.

Answer:

1372 cm^3

Step-by-step explanation:

To find the volume, you need to multiply height, length and width. In this question they are all given to us, so we just need to do the following:

volume = height*length*width

= 9 1/3cm*21cm*7cm (note that 9 1/3 could be simplified to 28/3)

= 1372 cm^3

We put ^3 at the end to show that it's a volume/3D.

I hope you can understand this :)

Answer: 1372

Step-by-step explanation:

Volume= length x width x height

Length= 21 cm

Width= 7 cm

Height= 9 1/3 cm

Multiply

21 x 7 x 9 1/3

147 x 9 1/3

* Note you can NEVER multiply mixed numbers like 9 1/3, so we have to make them improper.*

9 1/3 = 28/3

147 x 28/3= 4116/3

4116/3= 1372

Answer:

10976

Step-by-step explanation:

First lets start off by finding out how many cats there are (not kittens).

There were 7 girls, with 7 bags each, which contained 7 cats.

That turns into 7^3 or 7 * 7 * 7

7^3 = 343 cats

343 cats * 4 legs = 1372 legs (keep this for later).

Now you must find out how many kittens there are.

343 cats with 7 kittens each = 343 * 7

2401 kittens * 4 legs = 9604 legs

Now you must bring in the legs of the cats and kittens and add them together.

1372 legs (cats) + 9604 legs (kittens) = 10976 legs (total)

Step-by-step explanation:

Given:

1. Square stickers that were 3/4 in long

2. The spine is 10 and 1/2 in long

If she laid the stickers side by side without gaps or overlaps so the number of sticker to cover the length of the spine:

10 :  ≈13  

She needs 13 stickers cover the length of the spin

Answer:

what the top answer is

Step-by-step explanation:

The lengths of sides BC, DE, and EC in triangle DEC are given as \(4\) feet, \(1.8 feet,\) and 0.8 foot, respectively. The length of side \(AB\) is approximately \(3.36\) feet.

Part A:

To draw triangles  \(ABC\) and  \(DEC\) separately, follow the steps below:

Draw a straight line segment DE with length  \(1.8\) feet.

From point D, draw a line segment DC perpendicular to DE with length 4 feet.

Connect point E and point C with a straight line segment EC.

From point B, draw a line segment BE perpendicular to BC with length 0.8 foot.

Draw a straight line segment BC that intersects line segment DC at point A.

Connect point A and point B with a straight line segment AB.

The lengths of sides BC, DE, and EC in triangle DEC are given as \(4\) feet, \(1.8 feet,\) and 0.8 foot, respectively.

Part B:

Since triangles  \(ABC\) and \(DEC\) are similar, their corresponding sides are proportional. Let x be the length of side AB. Then we have:

\(AB/DE = BC/EC\)

Substituting the given values, we get:

\(x/1.8 = BC/0.8\)

Solving for BC, we get:

\(BC = 0.8x/1.8\)

Since BC and EC are the two legs of a right triangle DEC, we can use the Pythagorean theorem to find BC:

\(BC^2 + EC^2 = DE^2\)

Substituting the given values, we get:

\((0.8x/1.8)^2 + 4^2 = 1.8^2\)

Solving for x, we get:

\(x = 1.8 * (sqrt(1.8^2 - 4^2)) / 0.8\)

\(x \approx 3.36 feet\)

Therefore, the length of side \(AB\) is approximately \(3.36\)  feet.

Answer:

16b^4-9

Step-by-step explanation:

Factoring gives us 16b^4+12b^2-12^2-9. Simplifying gives us the answer which is 16b^4-9

Answer:

\(16b^4-9\)

Step-by-step explanation:

When multiplying binomials, we can use a method called FOIL (First-Outside-Inside-Last).

For \((t_1+t_2)(t_3+t_4)\), let:

\(t_1\implies \text{First Term},\\t_2\implies \text{Second Term},\\t_3\implies \text{Third Term},\\t_4\implies \text{Fourth Term}\)

In the FOIL method, the steps go:

\(\text{\textbf{F}irst: Multiply the first and third terms (first term of each binomial)},\\\text{\textbf{O}utside: Multiply the first and fourth terms},\\\text{\textbf{I}nside: Multiply the second and third terms},\\\text{\textbf{L}ast: Multiply the second and fourth terms (last term of each binomial) }\)

Given \((4b^2+3)(4b^2-3)\), we have:

\(\text{First: }4b^2\cdot 4b^2,\\\text{Outside: }4b^2\cdot -3,\\\text{Inside: }3\cdot 4b^2,\\\text{Last: }3\cdot -3,\\\rightarrow 16b^4-12b^2+12b^2-9\)

Combine like terms:

\(\boxed{16b^4-9}\)

Answer:

Step-by-step explanation:

The surface area of the figure is the total of the areas of the two triangular bases and the three rectangular faces.

  SA = 2(1/2)(8 cm)(6 cm) + (17 cm)(6 cm + 8 cm  + 10 cm)

  = 48 cm² + 408 cm²

  SA = 456 cm²

__

The volume is the product of the area of the triangular base and the length of the prism.

  V = (1/2)(8 cm)(6 cm)×(17 cm) = (24 cm²)(17 cm)

  V = 408 cm³

Step-by-step explanation:  

The angle measures of J and L are given as follows:

m < J = m < L = 65º.

To obtain the angle measures, we must considering that the sum of the measures of the internal angles of a triangle is of 180º.

The internal angles for this problem are given as follows:

Angles J and L are congruent, meaning that they have the same measure, which is obtained as follows:

50 + x + x = 180

2x = 130

x = 65º.
