Answer:
D
Step-by-step explanation:
D is the only answer given as a ratio, the rest are not.
Okay so first we would do .15 for 15%. after this step is finished We would multiply .15 to 17.00 getting you 2.25

La probabilidad que se pueden calcular es:
c: Probabilidad de que el chocolate no tenga relleno de piña.
<h3>
¿Como encontrar las probabilidades?</h3>
Sabemos que hay 25 chocolates en total en la caja, tal que:
- 8 son de mora.
- 5 son de piña
- los 12 restantes son de fresa o cereza.
La probabilidad de obtener un tipo particular de sabor se obtiene como el cociente entre el número de chocolates de ese sabor y el total de chocolates.
La probabilidad que se pueden calcular es:
c: Probabilidad de que el chocolate no tenga relleno de piña.
Sabemos que 5 chocolates tienen relleno de piña, entonces 20 no tienen relleno de piña. es decir, la probabilidad es:
P = 20/25 = 4/5

Answer:
68.27%
Step-by-step explanation:
An empirical rule for a normal distribution states that 68.27% of data is within 1 standard deviation () of the mean (), 95.45% of the data is within 2 standard deviations of the mean, and 99.73% of the data is within 3 standard deviations of the mean.
The problem asks for the probability that a battery will last between 6.8 and 9.2 hours considering that =8 and =1.2.
So, if the distribution is normal, the 68.27% of data is within 1, that is between and , replacing the values we have
8-1.2=6.8 and 8+1.2=9.2
So, 68.27% of batteries will last between 6.8 and 9.2 hours
