Concept explainers
To find: the mean, median, and mode of the given data.

Answer to Problem 13.1.5EP
The mean is
The median is
The mode is no mode.
Explanation of Solution
Given:
Populations (thousands) | ||||||
Population:
Consider the below data.
Find the mean, median, mode.
Mean:
Mean is sum of data points divided by the number of data points.
Here number of data points is
Hence, the mean is
Median:
Median is the middle number of the data ordered from lowest to greatest.
Data in increasing order is:
Here middle number is
Hence, the median is
Mode:
Mode is the number of numbers that occur more often.
No data point that occurs more often.
Hence, the mode is no mode.
Conclusion:
Hence, the mean is

- 2. The duration of the ride is 15 min. (a) How many times does the last passenger who boarded the ride make a complete loop on the Ferris wheel? (b) What is the position of that passenger when the ride ends?arrow_forward3. A scientist recorded the movement of a pendulum for 10 s. The scientist began recording when the pendulum was at its resting position. The pendulum then moved right (positive displacement) and left (negative displacement) several times. The pendulum took 4 s to swing to the right and the left and then return to its resting position. The pendulum's furthest distance to either side was 6 in. Graph the function that represents the pendulum's displacement as a function of time. Answer: f(t) (a) Write an equation to represent the displacement of the pendulum as a function of time.

Passengers must wait for their cage to be manually cranked into the lowest position in order to exit the ride. Sine function model: h = −82.5 cos (3πt) + 97.5 where h is the height of the last passenger above the ground measured in feet and t is the time of operation of the ride in minutes. (a) What is the height of the last passenger at the moment of the power outage? Verify your answer by evaluating the sine function model. (b) Will the last passenger to board the ride need to wait in order to exit the ride? Explain.arrow_forward
- The Colossus Ferris wheel debuted at the 1984 New Orleans World's Fair. The ride is 180 ft tall, and passengers board the ride at an initial height of 15 ft above the ground. The height above ground, h, of a passenger on the ride is a periodic function of time, t. The graph displays the height above ground of the last passenger to board over the course of the 15 min ride.
