Answer:
Step-by-step explanation: 6
The mean is the average, add the numbers together and divide by the number of students asked:
Mean = 4 + 15 + 19+ 11 + 6 + 16 + 9 + 15 = 95/8 = 11.875 rounded to the nearest tenth = 11.9
Median is the middle value, list the numbers from smallest to largest:
4, 6, 9, 11, 15, 15, 16, 19
There ia an even number, so find the middle two numbers, add them together and divide by 2:
Median = 11 + 15 = 26 / 2 = 13
Answer:
Area = 24.75 sqr units
Step-by-step explanation:
You will need these formulas:
Midpoint =
Area = b x h
Let us treat CD as the base. Find the length of the base with the distance formula. Use the coordinates for points C & D.
The base is .
The height is the distance between point E and the midpoint of line CD.
Midpoint of CD = = (, )
Use the distance formula to find the height.
Find the area with the two distances that were found.
Area =
Area =
Area = 24.75 sqr units
