A pharmaceutical company interviews 12 people for eight openings in the research department of the company. 7 of the 12 people a
viva [34]

Answer:

(a) 495, (b) 210

Step-by-step explanation:

Total number of persons = 12

number of openings = 8

number of women = 7

number of men = 12 - 7 = 5

(a) Number of ways to select the 8 persons

C_{8}^{12}\textrm{}\\\\= \frac{12!}{8!\times 4!}\\\\=495

(b) Three are men

So, 3 men and 5 women

The number of ways are

C_{3}^{5}\textrm{} \times C_{5}^{7}\textrm{}\\\\= \frac{5!}{3!\times 2!}\times \frac{7!}{5!\times 2!}\\\\=210

Se desea construir una letra "ene" mayúscula de tal manera que sus segmentos paralelos midan 25 cm y el
Anna71 [15]

Answer:

La distancia en línea recta que separa los segmentos paralelos es 60cm.

Step-by-step explanation:

Esta pregunta se puede resolver usando el <em>teorema de Pitágoras</em>:

\\ c^2 = a^2 + b^2 [1]

Es decir, en <em>triángulos rectágulos</em>, el cuadrado de la hipotenusa es igual a la suma de los cuadrados de los catetos de dicho triángulo. Un triángulo es rectángulo cuando el ángulo que forman sus dos catetos es recto o de 90 grados sexagesimales.

Es importante notar que la letra N tiene dos lados paralelos y el lado oblicuo (o inclinado) une ambos lados paralelos. Pues bien, la letra N puede formar dos triángulos iguales. Escojamos uno de ellos para obtener la respuesta, es decir, <em>la distancia en línea recta que separa los segmentos paralelos</em> (segmentos verticales de la N)

El <em>lado oblicuo</em> (inclinado) es la <em>hipotenusa de ese triángulo </em>(es decir, c)<em>. </em>De los catetos, uno está representado por uno de los <em>segmentos paralelos</em> (verticales) de la N (digamos que es b), y, el otro cateto, es la <em>distancia horizontal</em> que une ambos segmentos verticales (digamos que es a).

Si unimos el segmento inferior del <em>cateto b</em> con el extremo inferior de la <em>hipotenusa</em>, se forma el <em>cateto </em><em>a</em>. Este <em>cateto a</em> forma un ángulo recto con el cateto b y, por lo tanto, forma un triángulo recto. Los lados de un triángulo recto pueden resolverse usando el <em>teorema de Pitágoras</em>, descrito en [1].

Usando [1] y despejando a, tenemos:

\\ c^2 = a^2 + b^2

Restamos \\ b^2 de ambos lados de la igualdad:

\\ c^2 - b^2 = a^2 + b^2 - b^2

\\ c^2 - b^2 = a^2 + 0

\\ c^2 - b^2 = a^2

Luego

\\ a^2 = c^2 - b^2

Extrayendo la <em>raíz cuadrada</em> en cada lado de la igualdad:

\\ \sqrt{a^2} = \sqrt{c^2 - b^2}

Entonces

\\ a = \sqrt{c^2 - b^2}

Asimismo, tenemos que \\ c = 65cm y \\ b = 25cm

Entonces,

\\ a = \sqrt{65^2 - 25^2}

\\ a = \sqrt{4225 - 625}

\\ a = \sqrt{3600}

\\ a = 60cm

De esta manera, el valor de a, o <em>la distancia en línea recta que separa los segmentos paralelos</em>, es 60cm.

Podemos comprobar el resultado anterior haciendo uso del mismo <em>teorema de Pitágoras</em>:

\\ 65^2 = 60^2 + 25^2

\\ 4225 = 3600 + 625

\\ 4225 = 4225

En la figura anexa se aprecia gráficamente lo anteriormente explicado.

Studies have shown that 400 people attend a high school basketball game when the admission price is
Talja [164]

Answer:

Let x=number of $0.25 increases, so the equation for revenue=price*number of tickets or people) becomes

Revenue=($3.00+$0.25x)(400-20x)

where ($3.00+$0.25x) :increase in price

and

(400-10x) : decrease in number of people

Expanding Revenue

Revenue[R]=1200-60x+100x-5x²:1200+40x-5x²

Taking the derivative of R and set it equal to 0:

R'=0+40-10x=40-10x

we have

R'=0

40-10x=0

x=40/10

x=4

So the ticket price is $3.00+$0.25*4=$4

The number of people will attend is 400-20*4=$320

<u>At </u><u>$</u><u>3</u><u>2</u><u>0</u><u> ticket price will the revenue be maximized</u><u>.</u><u />
