I'm not too sure but i think:
A
_ r = x
Y
Answer:
a. 
.
b. 
Step-by-step explanation:
By the definition, the expected value of a random variable X with probability mass function p is given by 
where the sum runs over all the posible values of X. Given a function g, the random variable Y=g(X) is defined. Note that the function g induces a probability mass function P' given by P'(Y=k) = P(X=g^{-1}(k)) when the function g is bijective.
a. Note that for 1/3ln(2)+1/6ln(5) by choosing the function g(x) = ln(x) the expression coincides with E(g(x)), because if Y = g(x) then E(Y) = P'(Y=1)*ln(1)+P'(Y=2)*ln(2)+P'(Y=5)*ln(5) = P(X=1)*ln(1)+P(X=2)*ln(2)+P(X=5)*ln(5).
b. On the same fashion, the function g(x) = xe^{xt} fullfills the expression of E[g(X)]
Answer: dont know sorry
Step-by-step explanation:
Respuesta:
416
Explicación paso a paso:
El Área de la habitación:
Largo * ancho
Longitud = 15 pies
Ancho = 12 pies
Área de la habitación = Largo * Ancho
Área de la habitación = 15 pies * 12 pies
Área de la habitación = 180 pies²
Conversión del área de la habitación en patio²
Dividir el área en pies² por 9
180 pies² ÷ 9 = 20 yardas²
Costo de la alfombra por yarda cuadrada = 20.80
Costo total de la alfombra = 20.80 * 20 = 416
Answer: 582.7526
Step-by-step explanation:
p =3,14
r =13,4:2=6.7
r^2=44.89
SA= 3,14*44.89+3,14*6,7*21= 582,7526
