Given:
The data values are 13, 6, 12, 9, 11, 14, 2, 8, 18, 16, 9, 12, 17, 11, 19, 6, 7, 12, 22, 21, 18, 1, 8, 12, 18.
To find:
The frequency distribution table for given data values by using the class intervals 0-5, 5-10,..., and draw a histogram.
Solution:
The frequency distribution table for given data values is:
Intervals Data values Frequency
0-5 2,1 2
5-10 6,9,8,9,6,7,8 7
10-15 13,12,11,14,12,11,12,12 8
15-20 18,16,17,19,18,18 6
20-25 22,21 2
To draw the histogram, intervals must be represented on the x-axis and frequencies represented on the y-axis as shown below:

Question:
Howard is designing a chair swing ride. The swing ropes are 4 meters long, and in full swing they tilt in an angle of 23°. Howard wants the chairs to be 3.5 meters above the ground in full swing. How tall should the pole of the swing ride be? Round your final answer to the nearest hundredth.
Answer:
7.18 meters
Step-by-step explanation:
Given:
Length of rope, L = 4 m
Angle = 23°
Height of chair, H= 3.5 m
In this question, we are to asked to find the height of the pole of the swing ride.
Let X represent the height of the pole of the swing ride.
Let's first find the length of pole from the top of the swing ride. Thus, we have:
Substituting figures, we have:
Let's make h subject of the formula.
The length of pole from the top of the swing ride is 3.68 meters
To find the height of the pole of the swing ride, we have:
X = h + H
X = 3.68 + 3.5
X = 7.18
Height of the pole of the swing ride is 7.18 meters
