Answer:
its number 6
Step-by-step explanation:
For margin of error to be a maximum of 3:
3 = z*(SD / sqrt(n)), where z is the z-score, SD is the standard deviation and n is the sample size.
z = 1.96 for a 95% confidence interval, and we are given SD = 15.
3 = 1.96*15/sqrt(n)
sqrt(n) = 9.8
n = 96.04 ~ 96 commercials.

Answer:
Franco comió 8/3 de pizza.
Fabián comió 5/6 de pizza.
Queremos saber quien comió más.
Entonces básicamente queremos ver cuál número es más grande, 8/3 o 5/6,
Podemos reescribir el primero como:
8/3 = (2 + 3 + 3)/3 = 2/3 + 3/3 + 3/3 = 2/3 + 1 + 1
= 2 + 2/3
En cambio, para el número 5/6, el numerador es menor que el denominador, entonces sabemos que:
5/6 < 1
Claramente podemos ver que 8/3 > 5/6
Entonces podemos concluir que Franco comió más.
Answer:
62 days
Step-by-step explanation:
Given that she reads 9 pages everyday before falling asleep. Then, on day one, she would read 9m pages.
On day 2, she would read another 9 pages, making 18 pages after 2 days. If she will finish the book in x days then
x = 550/9
=61 1/9 days
Converting the 1/9 into a day then, she will finish the book in 62 days, reading just a page on the 62nd day.
