Answer:
the range of the given data set is 5/8
Step-by-step explanation:
Range is the difference between the largest value in a number set minus the smallest value in a number set.
In this case, the largest value is 1 1/4 and the smallest is 5/8
We simply just subtract those 2 numbers to find the range.
- 1 1/4 - 5/8
- Find the common denominator
- 1 2/8 - 5/8
- Make the first fraction an improper fraction
- 10/8 - 5/8
- 5/8

Answer: Period = 13.15 s
Solution:
The period of a pendulum is the time of pendulum takes to swing back and forth.
Function
Where,
L is length of pendulum in feet
T is time of pendulum in seconds
We have to calculate the time of pendulum whose length is 140 feet.
So, we substitute L=140 into formula
and to solve for t
We get t,
s
Period = 13.15 s
