8, 11, 12, 13, 16, 42
Add together and divide by 6 to get the mean.
102/6 = 17
Find the middle of the data for the median.
(12 + 13)/2 = 12.5
The mean is 17, the median is 12.5, and the mean is more affected by the outlier. 17 (the mean) is not a good measure of center.
Answer:25 parts of water to be added in 5 parts of powder .
Step-by-step explanation:
The ratio of powder to water required for a medicine is 1:5
If we have 5 parts of powder
To find : Parts of water to be added
Let x be the parts of water added when there is 5 parts of powder
Therefore we have
Powder 1 5
Water 5 x
Clearly, it is in direct variation
So we have
![\dfrac{1}{5}=\dfrac{5}{x}\\\\\Rightarrow x= 5\times 5 = 25](https://tex.z-dn.net/?f=%5Cdfrac%7B1%7D%7B5%7D%3D%5Cdfrac%7B5%7D%7Bx%7D%5C%5C%5C%5C%5CRightarrow%20%20x%3D%205%5Ctimes%205%20%3D%2025)
Hence, 25 parts of water to be added in 5 parts of powder.
Answer:
120
Interior angles have the same degree or #
Answer:
draw a line like this / through zero than draw another line like this \ through zero
Step-by-step explanation:
Answer:
37 degrees
Step-by-step explanation:
The first thing you have to do is realize all angles in a triangle have to add up to 180 degrees.
So you would make you equation
![2x + 15 + 5x - 2 + 90 = 180](https://tex.z-dn.net/?f=2x%20%20%2B%2015%20%2B%205x%20-%202%20%2B%2090%20%3D%20180)
Then you put all your constants on one side and the X's on the other. So you get
![7x = 77](https://tex.z-dn.net/?f=7x%20%3D%2077)
Then your x =11
To find that angle
![2x + 15](https://tex.z-dn.net/?f=2x%20%2B%2015)
You just plug in 11
![2(11) + 15](https://tex.z-dn.net/?f=2%2811%29%20%2B%2015)
=37
