La matemática financiera experimentó grandes avances con la creación de la banca y los negocios creados por los emprendedores. E

ste tipo de matemática se puede encontrar en las transacciones que realizan los concesionarios de carros, como en el siguiente caso: el costo anual (C de operación) de un automóvil nuevo es C= f + cm; f es el costo fijo (depreciación, seguros, impuestos), c es el costo de operación por kilómetro y m es el número de kilómetros recorridos. El costo total por 15000 Km es de 3000 USD, y el costo por 20000 Km es 3500 USD. Encuentra el costo fijo y el costo por kilómetro.

Answer:

c = \frac{1}{10}

f= 1500

Step-by-step explanation:

Tenemos la siguiente ecuación

C = f+cm

Tenemos los siguientes valores para m=15000, c = 3000 y para m = 20000, c=3500. Es decir, tenemos las siguientes ecuaciones

3000=f+c15000, 3500=f+c20000

Si restamos la segunda ecuación de la primera, tenemos que

3500-3000 = f-f+(20000c-15000c)

Luego

500 = 5000c

Entonces c = \frac{500}{5000} = \frac{1}{10}

Si tomamos la primera ecuación, tenemos que 3000-\frac{15000}{10} = f. Es decir,

3000-1500 = f = 1500

Esta solución, al plantear 2 ecuaciones y dos incógnitas, plantea un sistema dos por dos.

DATA ANALYSIS AND STATISTICSProbabilities involving two rolls of a dieAn ordinary (falr) die is a cube with the numbers 1 throug
Zepler [3.9K]

Solution

The table below is the required sample space of the to fair die

From the above table

The sample space contain 36 outcomes

Event A: The sum is greater than 9

we will look at the table and count all the elements that are greater than 9

There are 6 elements (they are 10, 10, 10, 11, 11, 12 from the table)

The probability for event A will be

\begin{gathered} p(A)=\frac{\text{required outcome}}{\text{total outcome}} \\ p(A)=\frac{6}{36} \\ p(A)=\frac{1}{6} \end{gathered}

P(A) = 1/6

Event B: The sum is an even number.

We will look at the table and count the number of elements that are even

There are 18 elements (notice that there are 3 even number on each of the 6 rows of the table)

The probability for event B will be

\begin{gathered} p(B)=\frac{\text{required outcome}}{\text{total outcome}} \\ p(B)=\frac{18}{36} \\ p(B)=\frac{1}{2} \end{gathered}

p(B) = 1/2

The sum of 3 consecutive odd numbers is 177. What is the value of the smallest number in the sequence
riadik2000 [5.3K]

Ok this is a very question that can solved very easily. So we know that there three numbers, and they are consecutive, this means that they are all one bigger than the number before so for example 1,2, and 3 or 20, 21, and 22. These numbers are called consecutive. Now let's just pretend that the answer to this question is the variable "x". Now x is the smallest number in all the three numbers.

Using our knowledge of consecutive numbers we can say that the next to numbers will be one more than the number before so:

(x+1) and (x+2)

So we have our three numbers: x , x+1 , and x+2. Now let's set these numbers equal to 177.

177 = x + x + 1 + x + 2 → Combine like terms.

177 = 3x + 3 → Subtract 3 from both sides.

174 = 3x → Divide both sides by 3

58 = x

So that means that our first and smallest number is going to be 58 our second number will be +1 so 59 and our third number will be +2 so 60.

So the three numbers will be 58, 59, and 60.

Hope this helped.
