Answer:
Method A.
Step-by-step explanation:
For solving this question we need to find out the z-scores for both methods,
Since, the z-score formula is,
![z=\frac{x-\mu}{\sigma}](https://tex.z-dn.net/?f=z%3D%5Cfrac%7Bx-%5Cmu%7D%7B%5Csigma%7D)
Where,
is mean,
is standard deviation,
Given,
For method A,
![\mu = 33](https://tex.z-dn.net/?f=%5Cmu%20%3D%2033)
![\sigma=8](https://tex.z-dn.net/?f=%5Csigma%3D8)
Thus, the z score for 34 is,
![z_1=\frac{34-33}{8}=0.125](https://tex.z-dn.net/?f=z_1%3D%5Cfrac%7B34-33%7D%7B8%7D%3D0.125)
While, for method B,
![\mu = 37](https://tex.z-dn.net/?f=%5Cmu%20%3D%2037)
![\sigma = 4](https://tex.z-dn.net/?f=%5Csigma%20%3D%204)
Thus, the z score for 34 is,
,
Since, ![z_1 > z_2](https://tex.z-dn.net/?f=z_1%20%3E%20z_2)
Hence, method A is preferred if the procedure must be completed within 34 minutes.
Answer:
A.
Step-by-step explanation:
X^2-5x+4
using "X" method you get out -4 and -1. (which make -5)
then plug that back in and you get:
(x-4) (x-1)=0
x=4
x=1
