Answer:
1. 2
2. 6
3. 2
4. 3
5. 1
6. 1
Step-by-step explanation:
First put the data in order from smallest to largest
2,2,2,3,3,6
The minimum is 2
The maximum is 6
The median is 2,2,2 ,3,3,6 is between the 2 and 3 (2+3)/2 = 2.5
The 1st quartile is 2,2,2 is the middle number = 2
The third quartile is 3,3,6 is the middle number is 3
The interquartile range is 3-2 =1
The mean average deviation is
First find the mean: ( 2+2+2+3+3+6)/6 =18/6 = 3
Then find how far each point is from the mean
(3-2) + (3-2) + (3-2) + (3-3) + (3-3) + (6-3) = 6
Divide this by the number of data points
6/6 =1
Answer:
Height = 5 ft
Short base = 10 ft
Long base = 14 ft
Step-by-step explanation:
Let h = height, a = short base, b = long base.
From the question,
a = 2h
b = a + 4 = 2h + 4
The area of the trapezoid is given by
. Thus,







or 
or 
We discard the negative value of h since it is a measurement and cannot be negative.
