Question 1:
For this case we have an equation of the form:
Where,
- <em>k: inverse variation constant. </em>
Then, substituting values we have:
From here, we clear the value of k.
We have then:
Answer:
the constant of inverse variation is:
Question 2:
For this case we have:
Where,
- <em>k: constant of variation. </em>
Then, substituting the value of the constant we have:
We now substitute the value of x:
Answer:
the value of y when x = 4 is:
Answer:
Step-by-step explanation:
The confidence interval for population mean is given by :-
, where is the sample proportion, n is the sample size ,
is the critical z-value.
Given : Significance level :
Sample size : n= 85
Critical value :
Sample proportion:
Now, the 99% confidence level will be :
Hence, the 99% confidence interval estimate of the true proportion of families who own at least one DVD player is
