The tangent plane equation of tangent plane is
z = x - 6y -1
This is further explained below.
What is the equation of the tangent plane to the surface z=ln(x-6y) at the point(7,1,0)?
Generally, Given surface is z = ln(x − 6y) ,
Given point is = (7, 1, 0)
partially differentiating with respect to x
== >zx = [1/(x - 6y)] (1) = 1/(x - 6y)
zx (7 , 1 , 0) = 1/(7 - 6(1)) = 1
Partially differentiating with respect to y
zy = [1/(x - 6y)] (-6)
zy = -6/(x - 6y)
zy(7 , 1 , 0) = -6/(7 - 6(1)) = -6
Equation of tangent plane is z - = zx(x -
) + zy(y -
)
z - 0 = 1(x - 7) + (-6)(y - 1)
z = x - 7 -6y + 6
z = x - 6y -1
In conclusion, equation of tangent plane is z = x - 6y -1

Answer:
For this case the population is described as:
All the college students
And the political have a list of 3456 undergraduates at her college for the sampling frame.
The sample would be the 104 students who return the survey.
Is important to notice that since he know the information about her college she can apply inference about the parameter of interest just at her college and not about all the possible students of college.
Step-by-step explanation:
For this case the population is described as:
All the college students
And the political have a list of 3456 undergraduates at her college for the sampling frame.
The sample would be the 104 students who return the survey.
Is important to notice that since he know the information about her college she can apply inference about the parameter of interest just at her college and not about all the possible students of college.
For this case we can also find the non reponse rate since we know that the total of questionnaires are 250 and she got back just 104 answered
So we have a non response rate of 58.4 %
