Answer:
thats easy its 52 but you have to -
Step-by-step explanation:
Which stem-and-leaf plot represents the data 80, 81, 91, 92, 66, 55, 54, 30, 55, 79, 78?
const2013 [10]
Convert the given data into ascending order.
30,54,55,55,66,78,79,80,81,91,92
Here the minimum value is 30 and maximum is 92.
Total counts=11
Now plot the data.
Stem | Leaf
3 | 0
5 | 4 5 5
6 | 6
7 | 8 9
8 | 0 1
9 | 1 2
This is the required stem leaf plot.
Answer:
or ![37\dfrac{1}{2}^{\circ}](https://tex.z-dn.net/?f=37%5Cdfrac%7B1%7D%7B2%7D%5E%7B%5Ccirc%7D)
Step-by-step explanation:
Given : The temperature of the liquid changed by
over
minutes.
We can write ![[tex]82\dfrac{1}{2}=\dfrac{82\times2+1}{2}=\dfrac{165}{2}](https://tex.z-dn.net/?f=%5Btex%5D82%5Cdfrac%7B1%7D%7B2%7D%3D%5Cdfrac%7B82%5Ctimes2%2B1%7D%7B2%7D%3D%5Cdfrac%7B165%7D%7B2%7D)
![2\dfrac{1}{5}=\dfrac{11}{5}](https://tex.z-dn.net/?f=2%5Cdfrac%7B1%7D%7B5%7D%3D%5Cdfrac%7B11%7D%7B5%7D)
Now, the statement becomes ,
The temperature of the liquid changed by
over
minutes.
i.e. temperature changed in
minutes = ![-\dfrac{165}{2}^{\circ}C](https://tex.z-dn.net/?f=-%5Cdfrac%7B165%7D%7B2%7D%5E%7B%5Ccirc%7DC)
Now, by Unitary method,
The temperature changed in 1 minute = ![\dfrac{165}{2}\times\dfrac{5}{11}^{\circ}C](https://tex.z-dn.net/?f=%5Cdfrac%7B165%7D%7B2%7D%5Ctimes%5Cdfrac%7B5%7D%7B11%7D%5E%7B%5Ccirc%7DC)
⇒ The temperature changed in 1 minute =
or ![37\dfrac{1}{2}^{\circ}](https://tex.z-dn.net/?f=37%5Cdfrac%7B1%7D%7B2%7D%5E%7B%5Ccirc%7D)
Well, assuming that you need to round to the nearest whole number, what is six closer to? 0, or 10? The answer is 10. Therefore, you would round up to 33. Hope this helps!
