Rocío y su hermano Rafael son aficionados al modelismo y tienen una colección de barcos y aviones. Rocío comentó: "Si tuviéramos once barcos más, tendríamos el mismo número de barcos y aviones", a lo que Rafael respondió: "Pero si tuviéramos doce aviones más, tendríamos el doble de aviones que de barcos". ¿Cuántos barcos y aviones tienen Rocío y Rafael?

3,750 deer

step-by-step explanation:

1,500 is 15 times larger than 100

lets make 250 15 times larger.

3750 deer

the answer is two. hope this !

d. 24+-0.114

step-by-step explanation:

the question requires us to calculate the approximate 95% confidence interval for the mean number of ounces of ketchup per bottle in the sample given the following statistics;

sample mean = 24

standard deviation, σ = 0.4

sample size , n = 49

the confidence interval for a population mean is calculated using the formula;

sample mean ± z-score*(σ/sqrt(n))

the z-score associated with a 95% confidence interval, from the standard normal tables, is;

1.96

substituting these values into the formula;

24 ± 1.96*(0.4/7)

= 24 ± 0.112

from the alternatives given, choice d is closest to the above expression;
