We have that an inverse variation in a function is given by:
We must find the value of the constant k.
To do this, we substitute the values of x1 = 12, y1 = 15.
We have then:
Clearing k we have:
Substituting the value of k we have that the inverse variation is:
For y2 = 3 we have:
Clearing x2 we have:

Answer:
Answer: 90% confidence interval would be
Step-by-step explanation:
Since we have given that
n₁ = 50
Number of metal tagged penguins survived = 10
So,
n₂ = 50
Number of electronic tagged penguins = 18
So,
So, at 90% confidence interval, z = 1.28
So, interval would be
Hence, 90% confidence interval would be
