20 sixth graders were asked: How many potted plants are in your home. Draw a histogram to represent the data, which is shown bel
ow. 0,1,2,2,3,4,4,5,5,6,6,6,6,7,7,8,8,9,11,12
1 answer:
Answer:
The histogram is attached below.
Step-by-step explanation:
The data for the number of potted plants every 20 sixth grader has in their home is:
S = {0, 1, 2, 2, 3, 4, 4, 5, 5, 6, 6, 6, 6, 7, 7, 8, 8, 9, 11, 12}
Form the frequency distribution of the data as follows:
<em>X</em> : 0 1 2 3 4 5 6 7 8 9 10 11 12
<em>Frequency</em>: 1 1 2 1 2 2 4 2 2 1 0 1 1
The histogram is attached below.
The mode of the data is, 6.
Since it has the highest frequency.

Hello,
r=5(1+cos t)
r'=5(-sin t)
r²+r'²= 25[(1+cos t)²+(-sin t)²]=50(1-cos t)=50 sin² (t/2)
Between 0 and π, sin x>0 ==>|sin x|=sin x
![l= 2*5* \int\limits^{\pi}_0{sin( \frac{t}{2} )} \, dt= 5[-cos (t/2)]_0^{\pi}\\\\ =5(0+1)=5](https://tex.z-dn.net/?f=l%3D%202%2A5%2A%20%5Cint%5Climits%5E%7B%5Cpi%7D_0%7Bsin%28%20%5Cfrac%7Bt%7D%7B2%7D%20%29%7D%20%5C%2C%20dt%3D%205%5B-cos%20%28t%2F2%29%5D_0%5E%7B%5Cpi%7D%5C%5C%5C%5C%0A%3D5%280%2B1%29%3D5)
Here is the method but i may have make some mistakes.
