Answer:
58.0
Step-by-step explanation:
Given the data:
56 65 62 53 68 58 65 52 56
Reorderd data: 52, 53, 56, 56, 58, 62, 65, 65, 68
Median = 1/2(n + 1) th term
n = sample size = 9
Hence,
Median = 1/2(9 + 1)th term
Median = 1/2(10)th term
Median = 5th term
5th term in the reordered data = 58
Hence, median age is 58

Answer:
35/3 ft = 11 2/3 ft
Step-by-step explanation:
We make a table of the lengths of the sides in descending order of side length. Each line contains two corresponding sides.
Quadrilateral Quadrilateral
ABCD EFGH
Side 1 20 ft ?
Side 2 18 ft ?
Side 3 14 ft 6 ft
Side 4 ? 5 ft
The line corresponding to side 3 is the only line that has the lengths of both corresponding sides.
The ratio of the length of sides in ABCD to EFGH is 14/6 = 7/3.
To find the length of the 4th sides of ABCD, we multiply the length of the 4th side of EFGH by the ratio.
7/3 * 5 ft = 35/3 ft = 11 2/3 ft
