Answer:
4.9 m
Step-by-step explanation:
Resolvemos la pregunta anterior usando la función trigonométrica de seno
sin θ = Opuesto / Hipotenusa
θ = 78 °
Hipotenusa = Longitud de la escalera = 5 m
Opuesto = Distancia sobre el suelo = x
sin 78 = x / 5m
Multiplicar cruzada
x = sin 78 × 5 m
x = 4.8907380037m
Aproximadamente
= 4.9 m
Hey, i dont know what bantu jawab ya guys mean
This is a binomial experiment and you'll use the binomial probability distribution because:
- There are two choices for each birth. Either you get a girl or you get a boy. So there are two outcomes to each trial. This is where the "bi" comes from in "binomial" (bi means 2).
- Each birth is independent of any other birth. The probability of getting a girl is the same for each trial. In this case, the probability is p = 1/2 = 0.5 = 50%
- There are fixed number of trials. In this case, there are 5 births so n = 5 is the number of trials.
Since all of those conditions above are met, this means we have a binomial experiment.
Some textbooks may split up item #2 into two parts, but I chose to place them together since they are similar ideas.
