A group of tourists is determining the order in which to visit national landmarks in Washington, DC. The group contains 200 people. Of those people, 150 are adults, and 50 are children. A random sample of tourists in the group is chosen. Surveying the random sample produced a representative sample of the population. Which was most likely true of the representative sample?

Answers

Answer: the representative sample contained more adults than children

Step-by-step explanation:

The options are:

a. The representative sample contained all 200 tourists.

b. The representative sample contained more adults than children.

c. The representative sample contained more children than adults.

d. The representative sample contained an equal number of adults and children.

Number of adults = 150

Number of children = 50

Total = 150 + 50 = 200

Probability of choosing an adult = 150/200 = 0.75

Probability of choosing a child = 50/200 = 0.25

The above shows that the representative sample contained more adults than children. This can be seen in the explanation above as number of adults is thrice that of children.

The area of a door is 3024 square inches. If the length of the door is 48 inches longer than the width of the door, what is the width of the door?​

Answers

Answer:

The width of the door is 36 inches

Step-by-step explanation:

The given parameters are;

The given area of the door = 3024 in.²

The length of the door = 48 + The width of the door

Let W represent the width of the door

Therefore, we have;

The length of the door = 48 + W

The area of the door = The length of the door × The width of the door

∴ By substitution, the area of the door = 3024 = W × (48 + W)

3024 = W × (48 + W) = 48·W + W²

48·W + W² = 3024

∴ 48·W + W² - 3024 = 0

Rearranging, we get;

W² + 48·W - 3024 = 0

By trial and error, we have;

(W + 84)×(W - 36) = 0

Therefore, given that the width of the door is a natural number, we have;

The width of the door, W = 36 inches
