Answer:

the probability of having a widow peak and attached earlobe = 0.6667*0.66667 = 0.4445 = 44.5%

Step-by-step explanation:

Martha = widow's peak + attached earlobes.

Martha's dad = straight hairline + unattached earlobes.

Martha husband =straight hairline+ widow's peak + attached earlobes

what is the probability that Martha child will have a widow's peak + attached earlobes?

since,

Martha + Martha husband =straight hairline+ widow's peak + attached earlobes

the probability of the child having widow peak is 2/3 = 0.6667

the probability of the child having attached earlobes is 2/3 = 0.66667

the probability of having both = 0.6667*0.66667 = 0.4445

Cual es el tiempo que debe transcurrir para que un préstamo de $ 160.000 genere un interés de $ 15.000 a una tasa del 5,5% de in
Vera_Pavlovna [14]

Answer:

2 años.

Step-by-step explanation:

De la pregunta anterior, se obtuvieron los siguientes datos:

Principal (P) = $ 160,000

Intereses (I) = $ 15,000

Tasa (R) = 5,5%

Tiempo (T) =?

Así, podemos obtener el tiempo que tarda el préstamo de $ 160.000 en generar un interés de $ 15.000 a una tasa de interés simple del 5,5% de la siguiente manera:

I = PRT / 100

15000 = 160000 × T × 5.5 / 100

15000 = 880000 × T / 100

15000 = 8800 × T

Dividir ambos lados por 8800

T = 15000/8800

T = 1,7

T ≈ 2 años

Por lo tanto, tomará aproximadamente 2 años.
