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.

Area of trapezoid = (B1 + B2)h/2

B1 = 15 in. + 4 in. + 6 in. = 25 in.
B2 = 15 in.
h = 7 in.

Area = (25 in. + 15 in.)(7 in.)/2 = 140 in.^2

MODELING REAL LIFE The height of the house is 26 feet. What is the height x of each story?T61tThe height x of each story isfeet
lozanna [386]

The total height of the building in the picture has been shown as

x + x + 6

That is, the first two storys have been shown as x feet each and the total height is 26 feet.

That means the two x are actually 20 feet, (if you deduct the 6 feet given)

Total height = x + x + 6

26 = x + x + 6

26 = 2x + 6

Subtract 6 from both sides of the equation

26 - 6 = 2x + 6 - 6

20 = 2x

Divide both sides of the equation by 2 and you now have,

20/2 = 2x/2

10 = x

Therefore, te height of each story is 10 feet!
