btw, u r not supposed to ask questions directly from assignments, quizzes, etc.
Step-by-step explanation:
the total distance traveled by a person sitting in the Ferris wheel would be
(if the full ride is 2 revolutions) => 2 ( 2πr) [ 2 times the circumference of the ferris wheel]
therefore,
=> 2 x (2 x 3.14 x 200)
=> 2 x 1256
=> 2512 feet
4.5 feet is 54 inches, and 127cm is 50 inches, so 50+54=104inches
Answer:
B
Step-by-step explanation:
Use SOHCAHTOA.
sinθ = ![\frac{opposite}{hypotenuse}](https://tex.z-dn.net/?f=%5Cfrac%7Bopposite%7D%7Bhypotenuse%7D)
Opposite side length= 12
Hypotenuse length = 37
Find the adjacent side length (b) using the Pythagorean theorem.
![12^2 + b^2 = 37^2](https://tex.z-dn.net/?f=12%5E2%20%2B%20b%5E2%20%3D%2037%5E2)
b = 35
tanθ =
= 12/35
Choice B is the correct answer.

The size of the sample is 23 scientists.
Answer:
Neighborhood Q appears to have a bigger family size
Step-by-step explanation:
Mean = the sum of all data values divided by the total number of data values
Number of families in Neighborhood Q = 9
Mean family size of Neighborhood Q:
= (2 + 5 + 4 + 3 + 2 + 5 + 3 + 6 + 5) ÷ 9
= 35 ÷ 9
= 3.888888...
Number of families in Neighborhood S = 9
Mean family size of Neighborhood S:
= (2 + 3 + 2 + 3 + 7 + 2 + 3 + 3 + 2) ÷ 9
= 27 ÷ 9
= 3
The mean family size of Neighborhood Q is 3.88.. and the mean family size of Neighborhood S is 3. Therefore, Neighborhood Q appears to have a bigger family size as it's average family size is bigger than that of Neighborhood S.
