The probability that a comic book reader in a particular city prefers comics published by Company A is 25%. The probability that
Andrew [12]
We know that 70% of all comic book fans are male, and that 40% of Company A fans are male. 

Since 25% of all comic book fans are company A fans: 
0.4 * 0.25 (meaning 40% of 25%) = 0.1, or 10% of all comic book fans are male company A fans. 

What percentage, then, of male comic book fans are company A fans?
0.1 ÷ 0.7 = 0.142
We divide 10%, the percentage of all comic book fans that are male and company A fans, by the percentage of comic book fans that are male, since we are given that the fan is male. 

Answer is 0.14

Answer:

See step by step

Step-by-step explanation:

To find if a function intervals are possible, make sure the points are above the x axis.

The graph is getting positve around x=-3 but it isn't positive yet.

The graph is positve until x=-1

The graph becomes positive again again at x=2 and is positive infinitely forever.

So let set up our interval

We are going to start at -3 since that where it start getting positive, we then going to use the greater than sign since it get positve as we go to the right as of right now. We use the greater than becuase we are not going to include -3 as our solutions.

We then use a less than sign since the answer must be less than -1 becuase around-1 it start getting negative.

It becomes positive again at x=2 so since we going to left to right use the greater than sign becuase we are not including 2.

It infinitely becomes positive so our interval is x must be cause greater than w becuase it can be any interval greater than two.

- 4 > x <  - 1

and

2 < x

The roots or zeroes are the x intercept of the graph,(when y=0, what is the x value.)

The x intercepts are -3 and 2.

Ayuda el tema en concreto es "Métodos de solución de ecuaciones simultáneas"
Mumz [18]

Answer:

<u>x = 3 y y = 2</u>

Step-by-step explanation:

a) Metodo de reduccion:

Para aplicar este metodo debemos multiplcar por 3 la ecuacion 2 y sumarlas.

4x-3y=6

5x+y=17 *3

4x-3y=6

15x+3y=51

-------sumamos las ecuacioens--------

19x=57

x=3

Ahora, remplazamos x en la ecuacion 2.

5(3)+y=17

y=2

b) Igualacion

Debemos despejar x en ambas y luego igualarlas

x=\frac{6+3y}{4}

x=\frac{17-y}{5}

Igualando:

\frac{6+3y}{4}=\frac{17-y}{5}

5(6+3y)=4(17-y)

19y=8

y=2

Ahora, remplazamos y en la ecuacion 2.

5x+2=17

5x=15

x=3

c) Sustitucion

Despejamos x de la primero ecuacion y lo remplazamos en dos.

x=\frac{6+3y}{4}

5\frac{(6+3y)}{4}+y=17

Multiplicamos por 4

5(6+3y)+4y=68

30+15y+4y=68

30+19y=68      

19y=38  

y=2  

Remplazando en 1.

4x-3(2)=6

4x-6=6

4x=12

x=3
