Answer:
n=106.1≅106
Option A which is 106 is correct
Step-by-step explanation:
In order to find the number of students need to be surveyed to meet the requirements we will use the following formula:

where:
n is the number of students need o be surveyed
Z is the distribution
S is the standard Deviation
E is the error Margin
Now:
S=8 ,E=2, CI= 99% or 0.99
For Z we need to find Alpha/2
Alpha=1-0.99
Alpha=0.01
Alpha/2=0.005 or 0.5%
From the cumulative Standard Distribution Table:
Z at alpha/2 =2.576
n= (2.576^2* 8^2)/2^2
n=106.1≅106
Option A which is 106 is correct
Answer:
The domain is all real numbers except x=6. The function tends to -infinity as x tends to 6- and to plus infinity as x tends to 6+.
