Michael and Mindy are working on a project about names. Using a phone book, Michael randomly selected ten people and recorded ho
w many letters their first names had. Then, he found the median number of letters. In all, he took 100 such samples. Mindy did the same with last names. The results are in the box plots below. Which statement is most accurate?
A. About 75% of the time, the median number of letters from the samples of first names was greater than or equal to 5. About the same percentage of the time, the median number of letters from the samples of last names was less than or equal to 5.
B. About 75% of the time, the median number of letters from the samples of first names was less than or equal to 6. About the same percentage of the time, the median number of letters from the samples of last names was greater than or equal to 6.
C. About 50% of the first names that were selected had either 5 or 6 letters. About the same percentage of last names that were selected had either 6 or 7 letters.
D. About 25% of the first names that were selected had fewer than 5 letters, while all of the last names that were selected had at least 5 letters.

Answer:
The total cost is $3,504.63
Step-by-step explanation:
Length of fence = 90 feet
Breadth of fence = 175 feet
Height of fence = 6 feet, 6 inches
1 inch = 0.0833333 feet
6 inches = 6*0.0833333 =0.4999998 feet
So, Height of fence = 6 feet + 0.49 feet =6.49 feet ≈ 6.5 feet
Perimeter =
Cost of erecting the fence is $1.25 per linear foot
So, Cost of erecting the fence in 530 feet =
Total surface area =
The cost of materials is $0.825 per square foot of fence
Cost of material for 3445 sq.feet =
So, total cost = 2842.125+662.5 = 3504.63
Hence The total cost is $3,504.63
