The median of Sample 1 is 83.5 and median of Sample 2 is 82.5.
Statistics is the discipline that concerns the collection, organization, analysis, interpretation, and presentation of data.
A random sample (Sample 1) from grades 9 and 10 showed scores of:
84, 50, 99, 83, 50, 78, 88, 85, 77, and 96.
Ascending order: 50, 50, 77, 78, 83, 84, 85, 88, 96, 99
The sample has an even number of scores, so the median is the average of the two middle scores:
(83 + 84)/2
= 83.5
Therefore, the median of Sample 1 is 83.5.
For sample 2, the data set is 57, 62, 86, 82, 74, 78, 96, 90, 97, and 83.
Ascending order of scores: 57, 62, 74, 78, 82, 83, 86, 90, 96, 97
The sample has an even number of scores,
so the median is the average of the two middle scores: (82 + 83)/2
= 82.5
Hence, the median of Sample 1 is 83.5 and median of Sample 2 is 82.5.

Step-by-step explanation:
There is no other answer. It is only 24
Hope it helps :)
The total of interior angles of a polygon is found using the formula 180 x (n-2) where n is the number of sides.
The above figure has 7 sides, so the total of the interior angles is: 180 x (7-2) = 180 x 5 = 900 degrees.
Find X:
Total all angles: 2x+4x+4x+4x+4x+2x+10x = 900
30x = 900
X = 900/30
x = 30
Angle A = 2x = 2*30 = 60 degrees
The answer is A.
C. 84*
