Fourteen runners in a marathon had these race times, in hours,
1 answer:
Answer:
Please find attached the histogram for the marathon runners
Step-by-step explanation:
The given data is presented as follows;
2.21
2.25
2.76
3.1
3.3
3.5
3.6
3.77
3.8
4.23
4.25
4.25
4.6
4.9
From the data, we have;
The frequency or number of runners that run between 0 and 1 hour = 0
The frequency or number of runners that run between 1 and 2 hours = 0
The frequency or number of runners that run between 2 and 3 hours = 3
The frequency or number of runners that run between 3 and 4 hours = 6
The frequency or number of runners that run between 4 and 5 hours = 5
With the above frequencies for the different data ranges, the histogram of the given data is then constructed as attached.

Consider the circle with center X, as shown in the figure.
Draw the diameter of the circle which is parallel to cherd AB, as shown in the figure.
Since the diameter and AB are parallel, then the line segment XC which bisects AB at C, will be perpendicular to AB.
SO triangle XCB is a right triangle. Thus the length of CX, by the Pythagorean theorem is
units.
Answer: 8 units
