Answer:
2.31
Step-by-step explanation:
A z-score tells us how many standard deviations above or below the mean a value is.
A z-score of 2.31 means that the score is 2.31 standard deviations above the mean. If the score were negative, it would be below the mean.
Answer:
<em>Farmer Bill sold 120 lb of potatoes</em>
Step-by-step explanation:
Suppose farmer Bill had x lb of potatoes. He sold a quarter to the first person. A quarter is written as (1/4)x. After that, Bill had x-(1/4)x = (3/4)x.
Then he sold 4/9 of what was left to the second person, thus it was left 1-4/9=5/9 of the remaining potatoes. Multiplying both factors:
This is the remaining portion of the potatoes.
Finally, he sold 4/5 of it and the last 10 lb. This means 1 - 4/5 = 1/5 of the remaining is equivalent to 10 lb:
Thus:
x = 120 lb
Farmer Bill sold 120 lb of potatoes
This is false the correct answer is 5.29

¿Como saber si un número es divisible por 6?</h3>
Para que un número sea divisible por 6 debe cumplir dos condiciones.
- Ser par.
- La suma de sus digitos debe ser multiplo de 3.
En este caso tenemos 12,480, que sabemos que es par.
La suma de sus digitos da:
1 + 2 + 4 + 8 + 0 = 15
15 es multiplo de 3.
Entonces este número cumple ambas condiciones, por lo que concluimos que 12,480 es divisible por 6.
