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:
13.75 hours
Step-by-step explanation:
First, find how many km the driver can travel:
11(35)
= 385
Then, divide this by 28 to find how many hours the driver can travel:
385/28
= 13.75
So, the driver can travel 13.75 hours
Answer:
22 tickets
Step-by-step explanation:
I assume you're asking about question 2
To find a fraction of a whole number you divide by the bottom number and multiply by the top number. If 2/3 are kids tickets then 1/3 are adult tickets so you divide by 3 and multiply by 1
The correlation coefficient of the data given in the table, using a calculator, is of 0.35
<h3>How to find the correlation coefficient of a data-set using a calculator?</h3>
To find the coefficient, we need to insert the points (x,y) in the calculator.
In this problem, we have that:
- The values of x are: 90, 95, 80, 84, 75, 80.
- The values of y are: 80, 90, 90, 95, 75, 85.
Using a calculator, the coefficient is of 0.35.
