Answer:

Step-by-step explanation:

From the answer choices available the answer that is correct is that for day-to-day business data analysis, most firms rely on a large staff of expert statisticians. This is because on a daily basis firms receive large sets of data from all of their business movements, therefore a large staff of highly experienced individuals is needed in order to handle and document all of these numbers carefully so that no mistakes are made. The smallest mistake in the firm's financial accounts can lead to a very costly loss for the company.

Calcula el lado y el área de un poligono regular 12 lados sabiendo que su radio es de 7,727dmy su apotema de 7,464
Vika [28.1K]

Answer:

L=3.999 \: dm

A=183.4581\:dm^{2}

Step-by-step explanation:

La relación del apotema y el lado de un dodecágono regular está dada por la siguiente ecuación:

a_{p}=L\frac{2+\sqrt{3}}{2}

Sabiendo que la apotema es 7.464 el lado sera:

L=\frac{2*a_{p}}{2+\sqrt{3}}

L=\frac{2*7.464}{2+\sqrt{3}}

L=3.999 \: dm

Por otro lado el area de un dodecágono regular esta dada por:

A=6a_{p}L

A=6*7.646*3.999

A=183.4581\:dm^{2}

FIND X IF AB=X+12, BC = x + 12₁ And AC = 14
MissTica

Given that B is a point between point A and C, the numerical value of x is -5.

<h3>What is the numerical value of x?</h3>

An equation is simply a mathematical formula that expresses the equality of two expressions, using the equals sign as a connection between them.

Given the data in the question;

  • B is a point between point A and C
  • Segment AC = 14
  • Segment AB = x + 12
  • Segment BC = x + 12
  • Numerical value of x = ?

Since B is a point between point A and C.

Segment AC = Segment AB + Segment BC

Plug in the given values and solve for the value of x

Segment AC = Segment AB + Segment BC

14 = (x + 12) + (x + 12)

14 = x + 12 + x + 12

14 = 2x + 24

2x = 14 - 24

2x = -10

x = -10/2

x = -5

Given that B is a point between point A and C, the numerical value of x is -5.
