Answer:
D. x = 0; y = -6
Step-by-step explanation:
There is a vertical asymptote at the value of x that makes the denominator zero. That value is x=0. This is sufficient to choose the correct answer.
When x gets large, the term 1/x nears zero, so the value of y nears -6. This is the horizontal asymptote.
vertical asymptote: x = 0; horizontal asymptote: y = -6
Answer:
We are 95% confident that the true proportion of adults overweight is between 0.644 and 0.672
Step-by-step explanation:
We can begin founding the estimated proportion of people overweight:
We need to find a critical value for the confidence level using the normal standard distribution. We know that 95% is the confidence level, then the significance level would be given by and
. And the critical value would be given by:
The confidence interval for the true population proportion of interest is given by the following formula:
Replacing the data provided we got:
We are 95% confident that the true proportion of adults overweight is between 0.644 and 0.672
