Answer:
a) Circumference of Ferris wheel.
b) 
c) 628 feet
Step-by-step explanation:
We are given the following in question:
Diameter of Ferris Wheel = 200 feet
a) Distance around Ferris wheel
The distance around Ferris wheel is given by the circumference of Ferris wheel.
b) Formula to calculate circumference

where d is the diameter of he wheel.
c) Distance traveled in one rotation
This will be given by the circumference of the Ferris wheel.

Thus, the distance traveled in one rotation is 628 feet.
Answer:
The confidence interval is 6.6<μ<6.8.
Step-by-step explanation:
We have:
Number of observations = 601
Mean = 6.7
Standard deviation σ = 1.5
The z-score for a 95% confidence interval is 1.96.
The limits of the confidence interval can be calculated as

The confidence interval is 6.6<μ<6.8.
Answer:
b = 87°
Step-by-step explanation:
In order to answer this question, we need to utilise an important angle fact which is <em>angles in a quadrilateral add up to 360° </em>
Using the information we can set up an equation to find the value of b
→ Form equation
63 + 140 + 70 + b = 360
→ Simplify
273 + b = 360
→ Minus 273 from both sides isolate b
b = 87°
