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
2x+8+ 120= 180
Combine like terms so 8+120=128
2x+8+ 120= 180
2x+128=180
-128=-128 ( to both side)
2x= 52 You divide now
2x/2= 52/2
x= 26
There is your answer :)
Picturing the tent helps, but we can actually solve this question using simple algebra and no knowledge of triangles.
The key is this function:
(b/h) = 2/√3
We want to get h by itself. First, multiply both sides by h:
b = h(2/√3) Now multiply both sides by the reciprical, (√3/2)
(√3/2) b = h
Therefore, the answer is C) h= b(√3/2)
