In the given question, there are several information's of immense importance and worth taking a look. based on these information's, the answer to the question can be easily determined.The length that has to be divided into 26 equal parts is 20 yards and 8 inches.Firstly we have to change the yard into inches and then we can divide the total inches into 26 equal parts.
We know
1 yard = 36 inches
20 yards = 720 inches
Then the total length that has to be divided = (720 + 8) inches
= 728 inches
Now we have to divide the 728 inches into 26 equal parts.
Length of each section = (728/26) inches
= 28 inches.
So each of the 26 parts will have a length of 28 inches.
You multiply the numerator and denominator of 3/4 with 3 and multiply 1/3 with 4 on the bottom and top and after you get 36/144 you simplify it and you get 1/4 so thats your answer

Step-by-step explanation:
Answer:
(a) The sample variance is 16.51
(a) The sample standard deviation is 4.06
Step-by-step explanation:
Given
Solving (a); The sample variance.
First, calculate the class midpoints.
This is the mean of the intervals.
i.e.
So, the table becomes:
Next, calculate the mean
Next, the sample variance is:
So, we have:
The sample standard deviation is:
76.3 rounded to the nearest whole number is 76
