The variable z is inversely proportional to x. When x is 19, z has the value 0.10526315789474. What is the value of z when x= 28
telo118 [61]

When two variables are inversely proportional the relation between them can be written as:

z=\frac{k}{x}

Here, k is the constant of proportionality and is always equal to the product of the two variables. So using the given values of z and x, we can find k first.

k=zx\\ \\  k=0.10526315789474(19)\\ \\  k=2

The constant of proportionality for the given inverse proportion comes out to be 2. Using the value of k in the equation, we get:

z=\frac{2}{x}

We have to find the value of z when x=28. So replacing x by 28, we get:

z=\frac{2}{28}\\  \\  z=0.07142857143

Thus, rounding of to nearest thousand the value of z comes out to be 0.071 if x is equal to 28.

Reporting cheating What proportion of students are willing to report cheating by other students? A student project put this ques
KonstantinChe [14]

Answer:

0.1105

Step-by-step explanation:

We know that question about reporting a cheating is asked to 172 students.

So the sample size would be n=172.

Out of 172 undergraduate students only 19 students answered "yes". It means that only 19 out of 172 students are willing to report cheating and so x=19.

According to definition of proportion

proportion=number of favorable outcome/total number of outcome

p=x/n

we are given that x=19 and n=172 so,

p=19/172=0.1105.

Hence according to given data 11.05% of students are wiling to report cheating by other students.
