Answer:
3.2 height
Step-by-step explanation:
54-31.6=22.4
15-8=7
22.4/7=3.2
The histogram of the distribution plotted on the y - axis and the interval for the length of time on the x - axis is attached below.
<h3>How to denote the histogram?</h3>
The first bar denotes the length of time between 0 and 10 having a frequency of 8. The second bar denoted the interval between 10 and 15 with a frequency of 15
The third bar denoted the interval between 15 and 20 with a frequency of 10. The fourth bar denoted the interval between 20 and 30 with a frequency of 11
Therefore, the histogram of the distribution is attached below.

Answer:
The number of palindromes is
when n is even and
when n is odd
Step-by-step explanation:
From the question we are told that
The length of the string is 
Generally palindrome is evaluated by considering the first part of a string
When the the length of the string is an even number then
it means that the first part of the string is 
Hence the number of bit strings of length n that are palindromes is evaluated as

But When the the length of the string is an odd number then
it means that the first part of the string is 
Hence the number of bit strings of length n that are palindromes is evaluated as

Generally each bit could be either 0 or 1
Hence the number of palindromes is
when n is even and
when n is odd
