The length of fourth side is: 8a-2

Step-by-step explanation:

Given

Perimeter = P = 39a-7

Side1 = s_1 =9a\\Side2=s_2=5a+1\\Side3=s_3=17a-6\\Side4=?

The perimeter is given by:

P = s_1+s_2+s_3+s_4\\39a-7 =9a+5a+1+17a-6+s_4\\39a-7=31a-5+s_4\\s_4=39a-31a-7+5\\s_4=8a-2

The length of fourth side is: 8a-2

Keywords: Perimeter, trapezoid

Un curso esta formado por 12 mujeres y 15 hombres ¿cual es la probabilidad de que las personas en el cargo de presidente y visep
riadik2000 [5.3K]

Answer:

P = (12/27)*(11/26) = 0.188

Step-by-step explanation:

Si todos tienen la misma probabilidad de estar en cargo de presidente y vicepresidente, entonces:

La probabilidad de que una mujer sea presidente, es igual al cociente entre el número de mujeres y el número total de personas:

p = 12/27

Ahora queremos calcular lo mismo para vicepresidente, y el cálculo es exactamente igual, con la diferencia de que en esta situación, ya hay una mujer en el cargo de presidente, entonces hay 11 mujeres que pueden ser vicepresidente, y un total de: (11 + 15 = 26 personas)

Entonces ahora la probabilidad es:

q = 11/26

La probabilidad conjunta (es decir, la probabilidad de que ambos eventos pasen) es igual al producto de las probabilidades individuales.

P = (12/27)*(11/26) = 0.188

Find (f+g)(x).
kaheart [24]

Answer:

(f+g)(x)  = x^3 - 3x + 2

Step-by-step explanation:

Find  (f+g)(x) by adding together f(x) = -3x + 2   and  g(x) = x^3:

  (f+g)(x) = -3x + 2 + x^3, or, in standard form,

(f+g)(x)  = x^3 - 3x + 2
