Answer:
Yes, \sqrt{2}(\sqrt{3.5} + 2\sqrt{5} )
Step-by-step explanation:
By roots property, the roots can be re-write as multiplications or division, like this:
![\sqrt[n]{a} . \sqrt[n]{b} =\sqrt[n]{ab}](https://tex.z-dn.net/?f=%5Csqrt%5Bn%5D%7Ba%7D%20.%20%5Csqrt%5Bn%5D%7Bb%7D%20%3D%5Csqrt%5Bn%5D%7Bab%7D)
Here, we can re-write both roots:
and 
Now we have:
And we can take out the common expression:

Answer:
A.) Mean = 237.9
B.) Median = 240
C.) Mode = 199
D.) Midrange = 239.5
Step-by-step explanation:
The given data are :
293 255 264 240 190 295 199 184 293 205 199
The mean = (sum of X) / f
Where frequency f = 11
X = 293 + 255 + 264 + 240 + 190 + 295 + 199 + 184 + 293 + 205 + 199
X = 2617
Substitute X and f into the formula
Mean = 2617/11
Mean = 237.9 approximately
B.) To get the median, you need to first rearrange the data, then pick the middle number.
184 190 199 199 205 240 255 264 293 293 295
The median = 240
C.) The mode is the highest frequency. That is the most occuring number
Mode = the two most occuring numbers are 199 and 293
D.) Range = highest number - lowest number
But midrange = (highest number + lowest number ) ÷ 2
Highest number = 295
Lowest number = 184
Substitute into the formula
Midrange = (295 + 184)/2
Midrange = 479/2
Midrange = 239.5
