The percentage of people under the age of 18 was 23.5% in New York City, 25.8% in Chicago, and 26% in Los Angeles.

Hatshy [7]

Answer:

0.0158 = 1.58% probability that all of them are under 18.

Step-by-step explanation:

Probability of independent events:

If three events, A, B and C are independent, the probability of all happening is the multiplication of the probabilities of each happening, that is:

$P(A \cap B \cap C) = P(A)P(B)P(C)$

The percentage of people under the age of 18 was 23.5% in New York City, 25.8% in Chicago, and 26% in Los Angeles.

This means that $P(A) = 0.235, P(B) = 0.258, P(C) = 0.26$

If one person is selected from each city, what is the probability that all of them are under 18?

Since the three people are independent:

$P(A \cap B \cap C) = 0.235*0.258*0.26 = 0.0158$

0.0158 = 1.58% probability that all of them are under 18.

If log(base4)x=2.5 and log(base Y)125=-3/2, find the numerical value of x/y, in simplest form.

Naya [18.7K]

X = (2^2)^(2.5)
x = 2^(2 * 2.5) 
x = 2^5 
x = 32
y^(-3/2) = 125
y^(-3) = 125^2 
y^(-3) = (5^3)^2 
y^(-3) = (5^2)^3 
y^(-3) = 25^3 
y = 25^(-1) 
y = 1/25 

x/y => 
32 / (1/25) => 
32 * 25 => 
800 is the simplest form of above
