Help help im so confused as per usual
Alik [6]

Answer:

Step-by-step explanation:

a. HM = 14

HN = 21

HK = 10.5

Based on intersecting chords theorem,

HK*HJ = HM*HN

10.5*HJ = 14*21 (Substitution)

HJ = 294/10.5

HJ = 28

b. VC = 7.2

VG = 12

Based on tangent-secant theorem, thus:

VD*VC = VG²

VD*7.2 = 12²

VD = 144/7.2

VD = 20

Therefore,

CD = VD - VC

CD = 20 - 7.2

CD = 12.8

the variable z is directly proportional to x. when x is 6, z has the value 18. what is the value of z when x = 10 the variable z
nikklg [1K]
Z\alpha x
Z=kX
When x=6, z=18,
Finding value of z,
18=k*6
k=3
Z=3X
when x=10,
Z=3*10
Z=30

Part B;
Z\alpha  \frac{1}{x}
z=\frac{a}{x}
Where x is a constant of proportionality,
when x=3, z=2
2=\frac{a}{3}
a=3*2
a=6
When x is 13,
Z=\frac{6}{13}

Marina CMI [18]

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

Non-resp. = \frac{250-104}{250} = \frac{146}{250}= 0.584

So we have a non response rate of 58.4 %
