What is the mean for the set of data shown below
27,32,14,19,24,26,22,32,29
2 answers:
The are 9 pieces of data in the set so we have:
(27+32+14+19+24+26+22+32+29)/9 = 25
25 is the mean of the set of data.
The mean of the data set is 25.
You can calculate the mean of a data set by adding all the values together, and then dividing that sum by the number of values.
27+32+14+19+24+26+22+32+29=225
225÷9=25

Answer: altitude: 5 cm
Explanation:
![\sf \dfrac{1}{2} ( a + b) h = Area \ of \ trapezium](https://tex.z-dn.net/?f=%5Csf%20%5Cdfrac%7B1%7D%7B2%7D%20%20%28%20a%20%2B%20b%29%20h%20%3D%20Area%20%5C%20of%20%5C%20trapezium)
[ <u>a and b are bases, h is the altitude</u> ]
Here given:
Solve for altitude:
![\sf \rightarrow \sf \dfrac{1}{2} ( 6 + 8) h = 35 \ \ \ \Rightarrow \ \ \ \dfrac{1}{2} ( 14) h = 35 \ \ \ \ \Rightarrow \ \ \ \ 7 h = 35 \ \ \ \ \Rightarrow \ \ h = \dfrac{35}{7} \ = \ 5](https://tex.z-dn.net/?f=%5Csf%20%5Crightarrow%20%5Csf%20%5Cdfrac%7B1%7D%7B2%7D%20%20%28%206%20%2B%208%29%20h%20%3D%2035%20%20%5C%20%5C%20%20%5C%20%20%5CRightarrow%20%20%5C%20%5C%20%5C%20%5Cdfrac%7B1%7D%7B2%7D%20%20%28%2014%29%20h%20%3D%2035%20%5C%20%5C%20%5C%20%5C%20%5CRightarrow%20%20%20%5C%20%5C%20%5C%20%20%5C%207%20h%20%3D%2035%20%5C%20%5C%20%5C%20%5C%20%20%5CRightarrow%20%5C%20%5C%20%20%20h%20%3D%20%5Cdfrac%7B35%7D%7B7%7D%20%5C%20%20%20%3D%20%20%5C%20%205)
I can’t see it but if I had to say it would be D.
