Answer:
I assume you mean...
"What are the roots of the polynomial and their multiplicity..."
x3+2x2+x = x(x2+2x+1) = x(x+1)(x+1) or x(x+1)2
The roots are x = 0, multiplicity 1
x = -1, multiplicity 2
Suppose the student guesses the answers, we shall consider this a binomial probability problem of success. This implies that getting a question right is p=1/5.
The number of questions is n=20 questions.
The mean of binomial distribution is
mean=n*p= 20*1/5=4
b] The standard deviation of a binomial distribution is given by:
σ=√(n*p*(1-p))
=√(20*0.2*0.8)
=1.79~1.8
Answer:
μ=4 ; σ=1.8
Usando proporciones, hay que con 200 pesos mx se pueden comprar 0.0645 yenes.
<h3>¿Qué es una proporción?</h3>
Una proporción es una fracción de la cantidad total, y puede ser encontrada por intermedio de una regla de tres.
En este problema, hay que un yene cuesta $0.17, enquanto $1 = 3100 pesos. Por eso, cada yene es equivalente a 3100 pesos.
Por eso, la <em>regla de tres</em> es:
1 yene - 3100 pesos
x yenes - 200 pesos
Aplicando multiplicación cruzada:
Con 200 pesos mx se pueden comprar 0.0645 yenes.
